【００５９】
また、平行移動させる量（Ｘ_S，Ｙ_S）は、次の式で得られる。
Ｘ_S ＝ Ｌ_p1＊ｃｏｓ（θ_p1−φｓ）
Ｙ_S ＝ Ｌ_p1＊ｓｉｎ（θ_p1−φｓ）
【００６０】
そして、Ｑ₁〜Ｑ_tのすべてを、次の式により、ＸＹ座標系の座標データ（Ｘ，Ｙ_i）に変換する（ステップＴ４）。
Ｘ_i＝Ｌ_i＊ｃｏｓ（θ_i−φｓ）−Ｘ_S （ｉ＝１〜ｔ）
Ｙ_i＝Ｌ_i＊ｓｉｎ（θ_i−φｓ）−Ｙ_S （ｉ＝１〜ｔ）
【００６１】
（ステップＴ５〜８）
つぎに、ＸＹ座標系に変換された各測定点Ｑ_i（Ｘ_i，Ｙ_i）が、部屋の上・下・左・右のいづれの辺の上にあるかどうか判断し、更に、Ｑ₁〜Ｑ_tの各測定点が、部屋の上下左右の辺の上の、何番目の間中測定箇所・小間中測定箇所を測定したものかを判定する（ステップＴ５〜８）。
【００６２】
すなわち、各測定点Ｑ_iのインデックス値iと、隅の点Ｑ_p1，Ｑ_p2，Ｑ_p3，Ｑ_p4のインデックス値Ｐ１，Ｐ２，Ｐ３，Ｐ４とを比較し、Ｐ１≦i≦ Ｐ２ の場合は、部屋の上の辺と判断し、Ｐ２≦i≦Ｐ３の場合は、部屋の右の辺と判断し、Ｐ３≦i≦Ｐ４の場合は、部屋の下の辺と判断し、Ｐ４≦i≦Ｐ１の場合は、部屋の左の辺と判断する。
【００６３】
そして、図１６に示すように、上の辺の間中・小間中測定箇所をＨＵ₁〜ＨＵ_nx、右の辺の間中・小間中測定箇所をＨＲ₁〜ＨＲ_ny、下の辺の間中・小間中測定箇所をＨＤ₁〜ＨＤ_nx、左の辺の間中・小間中測定箇所をＨＬ₁〜ＨＬ_nyと設定し、Ｑ₁〜Ｑ_tの各測定点が、上の辺、右の辺、下の辺、左の辺の各間中・小間中測定箇所のどれに当てはまるかを調べる（ｎｘは部屋の横方向の小間中測定箇所数、ｎｙは縦方向の小間中測定箇所数で、ＨＵ、ＨＲ、ＨＤ、ＨＬの参照インデックスが奇数であれば間中測定箇所、偶数であれば小間中測定箇所になる）。
【００６４】
部屋の上の辺にある測定点Ｑ_i（Ｘ_i，Ｙ_i）が、ＨＵ₁〜ＨＵ_nxのいづれに該当するかを判定するには、まず、対象とする測定点Ｑ_iが位置する辺の両端点（隅の点）Ｑ_p1（Ｘ_p1，Ｙ_p1）とＱ_p2（Ｘ_p2，Ｙ_p2）のデータから、各小間中測定箇所の間隔Ｗを次の式によって定義する。
Ｗ＝（Ｘ_p2−Ｘ_p1）／（ｎｘ−１）
【００６５】
そして、次の式を満たすｊの値を参照インデックスとするＨＵｊをＱ_iに対応する測定箇所と判定する。
Ｘ_p1＋Ｗ＊（ｊ−１）−Ｗ／２≦Ｘ_i＜Ｘ_p1＋Ｗ＊（ｊ−１）＋Ｗ／２
【００６６】
右の辺、下の辺、左の辺についても同様の処理を行い、こうして、全ての測定点Ｑｉが、部屋のどの辺の上の、何番目の間中・小間中測定箇所に当てはまるのか（ＨＵ、ＨＲ、ＨＤ、ＨＬのいづれの参照インデックスに対応するのか）を特定する。
【００６７】
また、実際に測定した測定点のなかに、間中測定の測定箇所のいずれかに対応する測定点がない場合は、その対応する測定点のない間中測定の測定箇所のデータを、その付近で実測されたデータから補間する。この場合の補間の手順は次のとおりである。
【００６８】
例えば、図１７に示すように、部屋の上の辺の間中測定の測定箇所ＨＵ_iのデータ（ＸＵ_i，ＹＵ_i）を補間によって求める場合、ＨＵ_i（ＸＵ_i，ＹＵ_i）が本来持つべきＸ座標値ＸＵ_iは、部屋の隅の点Ｑ_p1（Ｘ_p1，Ｙ_p1）とＱ_p2（Ｘ_p2，Ｙ_p2）のデータを基に、次の式によって定義される。
【数２】

【００６９】
このＸＵ_iに最も近いＸ座標値を持つ測定箇所を、部屋の上の辺の実際の測定点の中から、ＸＵ_iよりＸ座標値が小さい側と大きい側と双方で検索し、それら２測定点をそれぞれ、Ｑ_sn（Ｘ_sn，Ｙ_sn），Ｑ_sm（Ｘ_sm，Ｙ_sm）とすると、補間される点ＨＵ_iのＹ座標値ＹＵ_iは次の式による直線補間で求まる。
【数３】

【００７０】
（ステップＴ９）
このようにして、最低限「間中測定」に相当する測定箇所ＨＵ₁〜ＨＵ_nx，ＨＲ₁〜ＨＲ_ny，ＨＤ₁〜ＨＤ_nx，ＨＬ₁〜ＨＬ_nyの寸法表示とされたＸＹ座標データは、次いで、畳を製造する際の部屋の寸法の表し方である、部屋の基準寸法からの偏差で表すため、偏差寸法に変換する（ステップＴ９）。
【００７１】
部屋の基準寸法（Ｓ_x，Ｓ_y）は、ステップＳ３、４で入力した畳の基準サイズ「（五八、三六、本間）」と「部屋の大きさ（畳数）」から、次の式で計算される。
（部屋の横方向基準寸法Ｓ_x）＝Ｕ_s＊Ｍ_x
（部屋の縦方向基準寸法Ｓ_y）＝Ｕ_s＊Ｍ_y
【００７２】
ここで、Ｕ_sは、畳一枚の基準サイズ（五八＝５８００厘、三六＝６０００厘、本間＝６３００厘）であり、Ｍ_xおよびＭ_yは、横方向および縦方向に畳の並ぶ枚数である。
【００７３】
例えば、畳の基準サイズが「五八」で、部屋の大きさ（畳数）が「６畳」である場合、上記式によって計算される部屋の基準寸法は次のとおりである。
Ｓ_x＝５８００＊２＝１１６００厘
Ｓ_y＝５８００＊１．５＝８７００厘
【００７４】
こうして計算した部屋の基準寸法に対し、上記ＨＵ₁〜ＨＵ_nx，ＨＲ₁〜ＨＲ_ny，ＨＤ₁〜ＨＤ_nx，ＨＬ₁〜ＨＬ_nyのＸＹ座標データを、部屋の基準寸法を表す四角形より外にはみ出す寸法を正の寸法（＋）で、内に入り込む寸法を負の寸法（−）で表現した偏差寸法に変換する。すなわち、部屋の上辺の上の測定箇所ＨＵ_i（Ｘ_Ui，Ｙ_Ui）の場合、（−Ｙ_Ui）が偏差による寸法を表し、部屋の右辺の上の測定点ＨＲ_i（Ｘ_Ri，Ｙ_Ri）の場合、（Ｘ_Ri−Ｓ_x）が偏差による寸法を表し、部屋の下辺の上の測定点ＨＤ_i（Ｘ_Di，Ｙ_Di）の場合、（Ｙ_Di−Ｓ_y）が偏差による寸法を表し、部屋の左辺の上の測定点ＨＬｉ（Ｘ_Li，Ｙ_Li）の場合 （−Ｘ_Li）が偏差による寸法を表すよう変換する。図１８は、こうして偏差寸法に変換した部屋の寸法の一例を示している（この図の例は、「五八」基準で６畳の部屋の場合の寸法例である。図で、一点鎖線で表現されているのは、「五八」基準で６畳の部屋の場合の基準寸法を表す四角形である。）。
【００７５】
（ステップＴ１０）
つぎに、中柱の寸法および位置を計算する（ステップＴ１０）。その手順は次のとおりである。
【００７６】
測定したままの測定データＰ₁〜Ｐ_Sから、測定時にステップＳ１９で「中柱の測定」として記憶された４箇所（１つの中柱測定で４箇所の測定を行う）の測定点を探し出し、それらの測定点を、図１９に示すように、Ｐ_g1，Ｐ_g2，Ｐ_g3，Ｐ_g4とする。
【００７７】
そして、中柱の陰になって実際には測定できない壁側の隅２点Ｖ_g1，Ｖ_g4の座標を、Ｐ_g1〜Ｐ_g4から計算する。そのため、図２０に示すように、Ｐ_g1とＰ_g4を通る直線に対し、Ｐ_g2から垂直に直線を下ろして、その交点をＶ_g1とし、Ｐ_g1とＰ_g4を通る直線に対し、Ｐ_g3から垂直に直線を下ろして、その交点をＶ_g4とする。こうして疑似的に中柱の壁側の隅２点を決定し、Ｖ_g1（Ｌ_g1，θ_g1），Ｖ_g4（Ｌ_g4，θ_g4）の座標（Ｌ_g1，θ_g1），（Ｌ_g4，θ_g4）を計算する。
【００７８】
また、こうして得られた中柱の座標から、図２１に示すように２点間の距離を求める幾何学的な方法により、中柱の四辺の寸法ｗ₁、ｗ₂、ｗ₃、ｗ₄と、その中柱が位置する辺の片側の端をなす部屋の隅を基準点とした位置Ｆを計算する。
【００７９】
（ステップＴ１１）
つぎに、隅柱の寸法を計算する（ステップＴ１１）。その手順は次のとおりである。
【００８０】
測定したままの測定データＰ₁〜Ｐ_Sから、測定時にステップ１８で「隅柱の測定」として記憶された３箇所（１つの隅柱測定で３箇所の測定を行う）の測定データを探し出し、それらの測定点を、図２２に示すように、Ｐ_h1，Ｐ_h2，Ｐ_h3とする。
【００８１】
そして、ステップＴ１に関し図１３を参照して説明したのと同じ手法で、図２３に示すように、部屋の隅に相当する点Ｖ_hpを仮想的に設定する。そして、その座標を計算する。
【００８２】
そして、図２４に示すように、この仮想的な隅の点Ｖ_hpとＰ_h1とをつなぐ直線Ｌ_h1と、Ｖ_hpとＰ_h3とをつなぐ直線Ｌ_h3のそれぞれに対し、Ｐ_h2から垂線を下ろして、交点をそれぞれＶ_h1，Ｖ_h3とする。こうして疑似的に隅柱の壁側の隅２点を決定し、Ｖ_h1（Ｌ_h1，θ_h1），Ｖ_h3（Ｌ_h3，θ_h3）の座標（Ｌ_h1，θ_h1），（Ｌ_h3，θ_h3）を計算する。
【００８３】
また、こうして得られたＶ_hp，Ｖ_h1，Ｖ_h3，Ｐ_h2の計４点の座標から、図２５に示すように、２点間の距離を得る幾何学的な方法により、隅柱寸法ｗ₁、ｗ₂、ｗ₃、ｗ₄を算出する。
【００８４】
（第２の実施の形態）
第２の実施の形態は、請求項１〜５、７および９〜１１、特に請求項７に係る部屋の寸法表記のための測定及び計算方法である。
【００８５】
先の第１の実施の形態が、１部屋分の全ての測定点を測定した後で、４隅の測定点の判別を行うものであったのに対し、この第２の実施の形態は、各測定点の測定時に隅の測定となる点を判別し、隅の測定点であることを記憶する（請求項７）点に特徴がある。
【００８６】
図６〜８のフローチャートはこの第２の実施の形態の場合も同様である。以下、これらフローチャートに基づいて、第２の実施の形態における測定及び計算の手順の要点を説明する。
【００８７】
（スタート〜ステップＳ５）
まず、部屋のほぼ中央に測定装置本体Ａを設置する。
【００８８】
そして、電源を入れ、リモコン装置の確認キーによってリニア・エンコーダを基準長さにセットし（ステップＳ１）、リニア・エンコーダ３のカウンタ値をクリアし（ステップＳ２）、次いで、リモコン装置から、「畳の基準サイズ」を入力し（ステップＳ３）、「部屋の大きさ（畳数）」を入力し（ステップＳ４）、「現場名」「部屋番号」「畳の種類」などの付加的な情報を入力する（ステップＳ５）。
【００８９】
（ステップＳ６〜２３）
そして、まず最初の測定点に探触子（測定子）を当てて、リモコン装置を操作して測定し、次に、例えばその右側に次の測定点を任意に定めて、探触子を当てて測定を行い、同様に部屋の右回りに順次測定点を定めて、部屋の４隅に相当する測定点を必ず含むよう部屋の周囲一周の任意の測定点を測定する。その際、ＣＰＵ１は、リモコン装置から新たなキー入力があったかどうかを見て（ステップＳ６）、新たなキー入力があったときに次に進み、まず、その入力が「運転」キーかどうかを見る（ステップＳ７）。そして、今回のキー入力が「運転キー」かどうかで別の処理に進み、また、「運転」キーでないときは、「取消」キーかどうかを見て（ステップＳ８）、「取消」キーでなければ、「隅柱」キーかどうか（ステップＳ９）、「中柱」キーかどうか（ステップＳ１０）によって別の処理に進む。
【００９０】
キー入力が「隅柱」キーのときの処理は、第１の実施の形態で説明したものと同様で、隅柱測定モードにセットする（ステップＳ１８）。
【００９１】
また、キー入力が「中柱」キーのときは、やはり第１の実施の形態で説明したものと同様で、中柱測定モードにセットする（ステップＳ１９）。
【００９２】
また、キー入力が「取消」キーであるときは、直前に測定した１箇所のデータを削除する（ステップＳ１７）。
【００９３】
そして、「完了」キーが入力されたかどうかを判定し（ステップＳ１１）、「完了」キーが入力されたのでなければ、測定継続ということで、測定装置本体Ａが回転し測定動作を行っている途中（測定中）かどうかを判定し（ステップＳ１２）、測定中であれば、探触子から赤外線の再放射による応答信号が有ったかどうかを見て（ステップＳ１３）、応答信号が有ったときに測定装置本体Ａの回転を停止させる（ステップＳ１４）。そして、リニア・エンコーダ３およびロータリー・エンコーダ２から長さデータおよび角度データを読み取り（ステップＳ１５）、それらを順次新たな測定点のデータとして記憶させる（ステップＳ１６）。そして、ステップＳ６へ戻って、右回りの次の測定点を同様に測定するが、上記ステップＳ１６では、連続する３箇所の測定点Ｐ_k-2，Ｐ_k-1，Ｐ_kを測定した時点で、Ｐ_k-2とＰ_k-1を通る直線と、Ｐ_k-1とＰ_kを通る直線との、２直線のなす角度ωを計算して、このωの値により、ω＞＋４５度の場合、測定点Ｐ_k-1は部屋の隅の点と判定し、ω≦＋４５度の場合、Ｐ_k-1は部屋の辺の上の点であると判定し、測定点Ｐ_k-1が部屋の隅の点であるかどうかを、Ｐ_k-1の「長さデータ」「角度データ」とともに記憶させる。
【００９４】
中柱および隅柱の測定は、第１の実施の形態の場合と同様の操作によって行う。
【００９５】
そして、部屋の周囲全体の測定箇所を測定したら、リモコンで「完了」スイッチを操作して、１部屋分の測定を完了する。「完了」スイッチが押されると、ＣＰＵ１は、一部屋の測定完了の処理を行う（ステップＳ２３）。
【００９６】
そして、「部屋の大きさ（畳数）」を入力するステップ（ステップＳ４）に戻って、同様に次の部屋の測定を行い、測定すべき各部屋の全てについて同様の操作を繰り返し、各部屋ごとに測定データを記憶する。
【００９７】
また、キー入力が「運転」キーのときは、測定装置本体Ａが回転して測定動作を行っている途中（測定中）かどうかを見て（ステップＳ２０）、測定中であれば、一旦回転を停止して測定状態を解除する（ステップＳ２１）し、測定中でないとき、つまり測定解除の状態のときに回転を開始させ、測定状態に設定する（ステップＳ２２）。
【００９８】
（ステップＳ２４〜３０）
測定結果の表示あるいは印刷を行う場合は、リモコン装置の「印刷」キーあるいは「通信」キーを押すと、ＣＰＵ１は、「印刷」キーが押されたか「通信」キーが押されたかによって、プリンター印刷かパソコン送信かを判別する（ステップＳ２４）。そして、プリンター印刷の場合は、データを印刷する部屋を選択して（ステップＳ２５）、その部屋の測定データをＸＹ座標データに変換し、さらに基準寸法からの偏差寸法に変換するための処理を行い（ステップＳ２６）、その結果をプリンターに出力して印刷する（ステップＳ２７）。また、パソコン送信の場合は、パソコンへ送信する部屋を選択して（ステップＳ２８）、その部屋の測定データをＸＹ座標データに変換し、さらに基準寸法からの偏差寸法に変換するための処理を行い（ステップＳ２９）、その結果をパソコンに送信する（ステップＳ３０）。
【００９９】
なお、この場合も、ＸＹ座標表現に変換し、さらに標準的な部屋の形状である基準寸法からの偏差に変換した部屋の寸法を上記ステップＳ２７あるいはステップＳ３０でプリンターあるいはパソコンに出力し、表示・印刷するときに、実際に測定された箇所の寸法をそのまま表示・印刷することも可能であり、間中測定あるいは小間中測定の測定箇所の寸法を偏差寸法の形で表示・印刷することも可能である。そして、直線補間により追加された寸法を強調するため、反転表示（あるいは印刷）やカッコ付き寸法表示（あるいは印刷）などの手段でアクセントを付けることも可能である。
【０１００】
（ステップＴ１）
「長さデータ」と「角度データ」の極座標で表現された部屋ごとの測定データを、ＸＹ座標データに変換し、さらに基準寸法からの偏差寸法に変換するための処理（ステップＳ２６、ステップＳ２９）は、次の手順で行う。
【０１０１】
まず、１部屋分の測定データを抽出し、４隅の測定点を判別する（ステップＴ１）。ただし、この第２の実施の形態では、測定時に部屋の隅に当たる測定点かどうかを判別しながら各測定点を記憶しているので、隅柱がない場合、部屋の４隅の点Ｑ_p1，Ｑ_p2，Ｑ_p3，Ｑ_p4は既に特定できている。また、隅柱がある場合は、１部屋分の測定点Ｐ₁，Ｐ₂，・・・Ｐ_Sから隅柱の出張り側の角の測定点Ｐ_jと中柱の出張り側の両方の角の測定点のデータを除外し、それら測定点を、部屋を隅柱および中柱の無い四角形として扱うための測定点Ｑ₁，Ｑ₂，・・・Ｑ_tへと置き換える。その際、隅柱の位置に、第１の実施の形態と同様、仮想的な部屋の隅の点Ｑ_kを設定する。
【０１０２】
（ステップＴ２）
つぎに、測定点全体を回転させ、かつ、平行移動させることにより、Ｑ_p1がＸＹ座標の原点に、Ｑ_p2が正側のＸ座標軸上になるように、極座標系からＸＹ座標系（Ｘの正が水平右方向、Ｙの正が垂直下方向）へ変換するため、部屋の隅の２点Ｑ_p1とＱ_p2を探す（ステップＴ２）。
【０１０３】
（ステップＴ３〜８）
そして、第１の実施の形態と同様、ＸＹ座標への変換の為の変換パラメータとして、回転させるべき角度φｓと、平行移動させる量（Ｘ_S，Ｙ_S）を計算して（ステップＴ３）、Ｑ₁〜Ｑ_tのすべてを、ＸＹ座標系の座標データ（Ｘ_i，Ｙ_i）に変換し（ステップＴ４）、次いで、ＸＹ座標系に変換された各測定点Ｑ_i（Ｘ_i，Ｙ_i）が、部屋の上・下・左・右のいづれの辺の上にあるかどうか判断し、更に、Ｑ₁〜Ｑ_tの各測定点が、部屋の上下左右の辺の上の、何番目の間中測定箇所・小間中測定箇所を測定したものかを判定する（ステップＴ５〜８）。
【０１０４】
また、対応する測定点のない間中測定の測定箇所のデータは、補間によって求める。
【０１０５】
（ステップＴ９）
こうして、最低限「間中測定」に相当する測定箇所ＨＵ₁〜ＨＵ_nx，ＨＲ₁〜ＨＲ_ny，ＨＤ₁〜ＨＤ_nx，ＨＬ₁〜ＨＬ_nyについてＸＹ座標に変換したデータを、第１の実施の形態と同様、部屋の基準寸法からの偏差寸法に変換する（ステップＴ９）。
【０１０６】
（ステップＴ１０、１１）
つぎに、第１の実施の形態と同様の手順で、中柱の寸法および位置を計算し（ステップＴ１０）、隅柱の寸法を計算する（ステップＴ１１）。
【０１０７】
（第３の実施の形態）
第３の実施の形態は、請求項１および８〜１１、特に請求項８に係る部屋の寸法表記のための測定及び計算方法である。
【０１０８】
第１および第２の実施の形態では、隅柱・中柱を測定するときに、測定する直前にリモコンで「隅柱測定」「中柱測定」スイッチを押して、当該測定装置に隅柱・中柱の存在を入力していたのに対し、この第３の発明の形態は、「隅柱測定」「中柱測定」スイッチをリモコンから入力しなくても、測定点の幾何学的な位置関係から、隅柱・中柱の存在を自動的に認識できる構成（請求項８）としたものである。
【０１０９】
この第３の実施の形態における測定及び計算の手順を図２６および図２７のフローチャート（メインルーチン）と、図２８および図２９のフローチャート（サブルーチン）に基づき、また、図３０〜３５の説明図を参照して説明する。なお、以下の説明におけるステップＥ１〜２７は、図２６および図２７のフローチャートにおける各ステップを、また、ステップＰ１〜２１は、図２８および図２９のフローチャートにおける各ステップを指す。
【０１１０】
（スタート〜ステップＥ５）
まず、部屋のほぼ中央に測定装置本体Ａを設置する。
【０１１１】
そして、電源を入れ、リモコン装置の確認キーによってリニア・エンコーダを基準長さにセットし（ステップＥ１）、リニア・エンコーダ３のカウンタ値をクリアし（ステップＥ２）、次いで、リモコン装置から、「畳の基準サイズ」を入力し（ステップＥ３）、「部屋の大きさ（畳数）」を入力し（ステップＥ４）、「現場名」「部屋番号」「畳の種類」などの付加的な情報を入力する（ステップＥ５）。
【０１１２】
（ステップＥ６〜２０）
そして、一部屋の測定準備ということで、初期設定をし（ステップＥ６）、まず最初の測定点に探触子（測定子）を当てて、リモコン装置を操作して測定し、次に、例えばその右側に次の測定点を任意に定めて、探触子を当てて測定を行い、同様に部屋の右回りに順次測定点を定めて、部屋の４隅に相当する測定点を必ず含むよう部屋の周囲一周の任意の測定点を測定する。その際、ＣＰＵ１は、リモコン装置から新たなキー入力があったかどうかを見て（ステップＥ７）、新たなキー入力があったときに次に進み、まず、その入力が「運転」キーかどうかを見る（ステップＥ８）。そして、今回のキー入力が「運転キー」かどうかで別の処理に進み、また、「運転」キーでないときは、「取消」キーかどうかを見て（ステップＥ９）、「取消」キーでなければ、「完了」キーかどうかの判定（ステップＥ１０）に進む。
【０１１３】
また、キー入力が「取消」キーであるときは、直前に測定した１箇所のデータを削除する（ステップＥ１６）。
【０１１４】
「完了」キーが入力されたかどうかの判定（ステップＥ１０）に進み、「完了」キーが入力されたのでなければ、測定継続ということで、測定装置本体Ａが回転し測定動作を行っている途中（測定中）かどうかを判定し（ステップＥ１１）、測定中であれば、探触子から赤外線の再放射による応答信号が有ったかどうかを見て（ステップＥ１２）、応答信号が有ったときに測定装置本体の回転を停止させる（ステップＥ１３）。そして、リニア・エンコーダ３およびロータリー・エンコーダ２から長さデータおよび角度データを読み取り（ステップＥ１４）、それらを順次新たな測定点のデータとして記憶させる（ステップＥ１５）。そして、ステップＥ７へ戻って、右回りの次の測定点を同様に測定する。
【０１１５】
隅柱の測定をする必要が発生した場合は、第１および第２の実施の形態とは異なり、「隅柱」キーを押すことによって隅柱を測定できる状態にすることなく、単に、図９に示すように隅柱の周囲３箇所を測定する。また、中柱の測定をする必要が発生した場合は、単に、図１０に示すように中柱の周囲４箇所を測定する。
【０１１６】
そして、部屋の周囲全体の測定箇所を測定したら、リモコンで「完了」スイッチを操作して、１部屋分の測定を完了する。「完了」スイッチが押されると、ＣＰＵ１は、一部屋の測定完了の処理を行う（ステップＥ２０）。
【０１１６】
そして、「部屋の大きさ（畳数）」を入力するステップ（ステップＥ４）に戻って、同様に次の部屋の測定を行い、測定すべき各部屋の全てについて同様の操作を繰り返し、各部屋ごとに測定データを記憶する。
【０１１７】
また、キー入力が「運転」キーのときは、測定装置本体Ａが回転して測定動作を行っている途中（測定中）かどうかを見て（ステップＥ１７）、測定中であれば、一旦回転を停止して測定状態を解除する（ステップＥ１８）し、測定中でないとき、つまり測定解除の状態のときに回転を開始させ、測定状態に設定する（ステップＥ１９）。
【０１１８】
（ステップＥ２０〜２７）
測定結果の表示あるいは印刷を行う場合は、リモコン装置の「印刷」キーあるいは「通信」キーを押すと、ＣＰＵ１は、「印刷」キーが押されたか「通信」キーが押されたかによって、プリンター印刷かパソコン送信かを判別する（ステップＥ２１）。そして、プリンター印刷の場合は、データを印刷する部屋を選択して（ステップＥ２２）、その部屋の測定データをＸＹ座標データに変換し、さらに基準寸法からの偏差寸法に変換するための処理を行い（ステップＥ２３）、その結果をプリンターに出力して印刷する（ステップＥ２４）。また、パソコン送信の場合は、パソコンへ送信する部屋を選択して（ステップＥ２５）、その部屋の測定データをＸＹ座標データに変換し、さらに基準寸法からの偏差寸法に変換するための処理を行い（ステップＥ２６）、その結果をパソコンに送信する（ステップＥ２７）。
【０１１９】
なお、この場合も、ＸＹ座標表現に変換し、さらに標準的な部屋の形状である基準寸法からの偏差に変換した部屋の寸法を上記ステップＥ２４あるいはステップＥ２７でプリンターあるいはパソコンに出力し、表示・印刷するときに、実際に測定された箇所の寸法をそのまま表示・印刷することも可能であり、間中測定あるいは小間中測定の測定箇所の寸法を偏差寸法の形で表示・印刷することも可能である。そして、直線補間により追加された寸法を強調するため、反転表示（あるいは印刷）やカッコ付き寸法表示（あるいは印刷）などの手段でアクセントを付けることも可能である。
【０１２０】
（ステップＰ１）
「長さデータ」と「角度データ」の極座標で表現された部屋ごとの測定データを、ＸＹ座標データに変換し、さらに基準寸法からの偏差寸法に変換するための処理（ステップＥ２３、ステップＥ２６）は、次の手順で行う。
【０１２１】
この第３の実施の形態は、「長さデータ」「角度データ」からなる極座標データをＸＹ座標変換する前に、隅柱・中柱の測定点を特定するための処理を行うもので、スタートすると、まず、一部屋分の測定データを抽出する（ステップＰ１）。
【０１２２】
（ステップＰ２）
そして、まず、各測定点を部屋の直線部分と非直線部分（部屋の隅、隅柱、中柱を含む）とに切り分ける処理を行うため、まず、最初の測定点Ｐ_k（ｋ＝１）を特定する（ステップＰ２）。
【０１２３】
（ステップＰ３）
そして、その最初の測定点Ｐ_k（ｋ＝１）から始め、任意の測定点Ｐ_kについて、その前後の測定点Ｐ_k-1（最後の測定点）とＰ_k+1（例えば右回り場合の右隣）の測定データから、測定点Ｐ_kにおける部屋の曲がり具合ω_k（Ｐ_k-1とＰ_kとを結ぶ直線と、Ｐ_kとＰ_k+1とを結ぶ直線とがなす角度）を計算し、このω_kが、所定のしきい値αに対して、−α＜ω_k＜αを満たすかどうかによって、図３０の（ａ）に示すように、測定点Ｐｋが部屋の直線部分の測定点であるか、図３０の（ｂ）に示すように、非直線部分の測定点かを判定する（ステップＰ３）。
【０１２４】
−α＜ω_k＜αを満たす場合、Ｐ_kは直線部分の測定点（ωｋは０度付近）である。通常、部屋の直線部分の歪み具合は、図３１に示すように、半間（半畳の畳の１辺の長さ：およそ三尺＝９０９ｍｍ）の距離で、五分（およそ１５ｍｍ）以下の歪みであることが殆どであることからすれば、αをおよそ１度に設定することで、直線部分か非直線部分かの判断ができる。しかし、実際には、少し歪みが大きい場合でも確実な判定を行うために、やや余裕をとって、αを３〜１０度くらいに設定する。
【０１２５】
（ステップＰ４）
そして、ω_kが、−α＜ω_k＜αを満たす場合は、その測定点Ｐ_kを直線上の点と判定し、記憶させる（ステップＰ４）。
【０１２６】
（ステップＰ５）
また、ω_kが、−α＜ω_k＜αを満たさない場合は、その測定点Ｐ_kは非直線部分の点ということで、更に、部屋の隅の点かあるいは隅柱・中柱の測定点かを判定するため、まず、測定順の次の測定点Ｐ_k+1における曲がり具合の角度ω_k+1と−αとの大小関係を見る（ステップＰ５）。
【０１２７】
（ステップＰ６）
そして、ω_k+1＞−αの場合は、図３２に示すように、Ｐ_kは部屋の隅の点であると判定し、記憶させる（ステップＰ６）。
【０１２８】
（ステップＰ７）
また、ω_k+1≦−αの場合は、図３３に示すように、Ｐ_kは隅柱または中柱の第１測定点であるということで、更に、隅柱の測定点か、それとも中柱の測定点かを調べるために、測定順の更に次の測定点Ｐ_k+2における曲がり具合の角度ω_k+2の値を見る（ステップＰ７）。
【０１２９】
（ステップＰ８）
そして、ω_k+2≧０の場合は、図３４に示すように、Ｐ_kを隅柱の第１測定点と判定し、また、Ｐ_k+1を第２測定点、Ｐ_k+2を第３測定点とする（ステップＰ８）。

（ステップＰ９）
また、ω_k+2＜０の場合は、図３５に示すように、Ｐ_kを中柱の第１測定点と判定し、また、Ｐ_k+1を第２測定点、Ｐ_k+2を第３測定点、Ｐ_k+3を第４測定点とする（ステップＰ９）。
【０１３１】
（ステップＰ１０）
こうして、あるｋについて測定が終わると、全ての測定点Ｐ₁，Ｐ₂，・・Ｐ_Sについて、同じ方法で、順次、各測定点について、部屋の直線上の点か、非直線部分の「部屋の隅」か「隅柱」か「中柱」かを特定するため、ｋに１を足す（ステップＰ１０）。
【０１３２】
（ステップＰ１１）
そして、測定点全てのｋについて測定点を特定したかどうかを見て（ステップＰ１１）、まだ特定していない測定点がある場合は、上記処理を繰り返す。
【０１３３】
（ステップＰ１２）
全ての測定点の特定が終了すると、ＸＹ変換の処理に入る。
【０１３４】
この第３の実施の形態の場合、「部屋の隅」、「隅柱」、「中柱」の測定点の特定は既にできている。そして、隅柱がない場合の、部屋の４隅の点Ｑ_p1，Ｑ_p2，Ｑ_p3，Ｑ_p4は特定できている。また、隅柱がある場合は、１部屋分の測定点Ｐ₁，Ｐ₂，・・・Ｐ_Sから隅柱の出張り側の角の測定点Ｐ_jと中柱の出張り側の両方の角の測定点のデータを除外し、それら測定点を、部屋を隅柱および中柱の無い四角形として扱うための測定点Ｑ₁，Ｑ₂，・・・Ｑ_tへと置き換える。その際、隅柱の位置に、第１の実施の形態と同様、仮想的な部屋の隅の点Ｑ_kを設定する。
【０１３５】
そこで、まず、測定点全体を回転させ、かつ、平行移動させることにより、Ｑ_p1がＸＹ座標の原点に、Ｑ_p2が正側のＸ座標軸上になるように、極座標系からＸＹ座標系（Ｘの正が水平右方向、Ｙの正が垂直下方向）へ変換するため、部屋の隅の２点Ｑ_p1とＱ_p2を探す（ステップＰ１２）。
【０１３６】
（ステップＰ１３〜１８）
そして、第１の実施の形態と同様、ＸＹ座標への変換の為の変換パラメータとして、回転させるべき角度φｓと、平行移動させる量（Ｘ_S，Ｙ_S）を計算して（ステップＰ１３）、Ｑ₁〜Ｑ_tのすべてを、ＸＹ座標系の座標データ（Ｘ_i，Ｙ_i）に変換し（ステップＰ１４）、次いで、ＸＹ座標系に変換された各測定点Ｑ_i（Ｘ_i，Ｙ_i）が、部屋の上・下・左・右のいづれの辺の上にあるかどうか判断し、更に、Ｑ₁〜Ｑ_tの各測定点が、部屋の上下左右の辺の上の、何番目の間中測定箇所・小間中測定箇所を測定したものかを判定する（ステップＰ１５〜１８）。
【０１３７】
また、対応する測定点のない間中測定の測定箇所のデータは、補間によって求める。
【０１３８】
（ステップＰ１９）
こうして、最低限「間中測定」に相当する測定箇所ＨＵ₁〜ＨＵ_nx，ＨＲ₁〜ＨＲ_ny，ＨＤ₁〜ＨＤ_nx，ＨＬ₁〜ＨＬ_nyについてＸＹ座標に変換したデータを、第１の実施の形態と同様、部屋の基準寸法からの偏差寸法に変換する（ステップＰ１９）。
【０１３９】
（ステップＰ２０、２１）
つぎに、第１の実施の形態と同様の手順で、中柱の寸法および位置を計算し（ステップＰ２０）、隅柱の寸法を計算する（ステップＰ２１）。
【０１４０】
（第４の実施の形態）
第１〜３の実施の形態では、測定した部屋の寸法を、全て、「間中測定位置」と「小間中測定位置」での寸法で表しているが、この第４の実施の形態では、測定点を「間中測定位置」「小間中測定位置」に振り分けるのではなく、測定した点のＸＹ座標上における座標値（Ｘ_n，Ｙ_n）のまま（単位は任意）表示・印刷する。
【０１４１】
すなわち、図３６に示すように、部屋の周囲一周について４隅を含む任意の測定点を測定する。そして、各測定点の長さデータと角度データからなる極座標データを、４隅の測定点の一つがＸＹ座標の原点となり隣接する他の２隅の測定点がＸ軸上およびＹ軸上に重なるＸＹ座標データに変換し、そのＸＹ座標データの形で部屋の寸法を表記する。
【０１４２】
この方法によれば、部屋の各辺のなかでも特に歪みの大きいところ（歪みの凹凸の頂点と谷点）と部屋の４隅を測るだけでも、部屋の大凡正確な形状を測定することができる。
【０１４３】
（第５の実施の形態）
第１〜４の実施の形態では、各測定点の測定する順序は、最初の測定点から順に時計回りあるいは反時計回りに測定するというものであったのに対し、この第５の実施の形態では、部屋の４隅の点を含んでさえいれば（隅柱がある場合は、仮想的な隅の点を設定することで可）、各測定点の測定する順序は基本的に問わないものである。この場合、１部屋分の全ての測定点を測定した後、各測定点の角度データの値を見て、測定点を昇順（時計回りあるいは反時計回りの順）に並べ替える。その際、角度データが３５９度から０度の間の変化も昇順と見なすような取り扱いを行う。そうすることで、時計回りあるいは反時計回りに測定したのと同等になる。
【０１４４】
（第６の実施の形態）
第１〜５の実施の形態では、測定から寸法の変換・表示・印刷までのすべてを、寸法測定装置で行っていたのに対し、この第６の実施の形態では、各測定点の測定だけを寸法測定装置によって行い、測定した各測定点の長さデータと角度データを極座標形式のまま、パソコンなどの外部の計算処理機器に送信・入力し、その外部の計算処理機器で、ＸＹ変換や偏差への変換を行い、表示・印刷を行う。
【０１４５】
【発明の効果】
本発明によれば、間中測定とか小間中測定とかの定められた測定箇所および測定箇所数にとらわれずに、任意の測定点の長さデータと角度データを測定することにより、部屋の寸法を計算し表記することができ、中柱や隅柱が出張っている部屋の寸法も容易に測定でき、また、測定した長さデータと角度データからなる極座標データを、部屋の基準寸法に対し回転方向のずれのないＸＹ座標系のデータに容易に変換できる。

BACKGROUND OF THE INVENTION
  The present invention measures and calculates to measure the dimensions of a room when cutting tatami mats, carpets, etc. according to the shape of the room, and to indicate the dimensions for cutting by numerical control, etc.MethodIn particular, from the length data and angle data of the measurement points around the room measured with reference to a predetermined position near the center of a substantially rectangular room, the room dimensions are calculated and converted into data suitable for cutting. Measurement and calculation for notationMethodAbout.
[0002]
[Prior art]
  When laying tatami mats and carpets in a room, measure the actual dimensions of the room, and in the case of tatami mats, assign them to 6 or 8 tatami mats and cut them. In such a case, for example, in the case of a tatami mat, the dimensions of the room to be measured are Gohachi (5 x 8 x 2 x 9), 36 (6 x 3 x), Honma (6 x 3 x 3 x 1). Usually, it is expressed as a deviation from the standard size of the room determined by the standard size of one tatami mat and the number of tatami mats (5 minutes).
[0003]
  And, as a measurement method for expressing the room dimensions by deviation from the reference dimensions, the room dimensions are usually taken by “measuring measurement” where the number of measurement points is small and the measurement time is short. In particular, in a place where distortion is particularly large in a sill around the area, a method of measuring the size more finely by “measuring booth” is generally used.
[0004]
  In the intermediate measurement, for example, in the case of a room with 4 tatami mats, the specified measurement points are set at 12 places including 4 corners, and in the case of 6 tatami mats, including 14 corners, and the data measured at these measurement points is used. Based on this, the deviation from the standard dimension of the room is calculated, and the dimension that protrudes outside the square representing the standard dimension is represented by a positive dimension (+), and the dimension that enters the interior is represented by a negative dimension (−). In the booth measurement, set the specified measurement points at 24 points including 4 corners in the case of 4 tatami mats and 28 points including 4 corners in the case of 6 tatami mats, and based on the data measured at these measurement points. Also, the deviation from the standard dimension of the room is calculated and expressed in the same way with positive and negative dimensions.
[0005]
  Then, anyone can accurately measure the dimensions of the room in order to express the dimensions of the room by deviation from the standard dimensions, without any experience or skill, and with a measuring device that is convenient to carry. Therefore, as described in, for example, Japanese Patent Laid-Open No. 9-304068, a base, a turntable rotatably mounted on the base, and a mount on the turntable A rotary encoder that detects the rotation angle of the turntable with respect to the base, and a linear that is placed on the turntable and winds a wire or tape, and detects the length of the drawn wire or tape. -An encoder, a laser light source mounted on the turntable and emitting a laser beam in the direction of the turntable, and a sharp tip connected to the tip of a wire or tape Probe, a response device that re-emits the beam when receiving a laser beam, and aligns the tip of the probe with the reference point to be measured that exists in the pointing direction. An inventor of the present invention has been proposed for a room size measuring device including a storage device for storing angle data and length data when a light beam is re-emitted from the device.
[0006]
  A conventional dimension measuring method using the dimension measuring apparatus described in Japanese Patent Application Laid-Open No. 9-304068 is as follows. That is, as shown in FIGS. 1A and 1B, when a measuring apparatus main body is installed in the center of a room and the room is measured, for example, clockwise (clockwise), the laser beam is first emitted. The visible laser beam radiation direction is set slightly to the left of the first measurement point, and the initial setting conditions such as the standard size of the tatami mat (58, 36, Honma) and the room size (number of tatami mats) input. According to the input initial setting conditions, 12 locations for 4 tatami mats, 14 locations for 6 tatami mats, 14 locations for 6 tatami mats, 24 locations for 4 tatami mats and 28 locations for 6 tatami mats, depending on the initial setting conditions entered. The measurement location and the number of measurement points are set in. And after pulling out the wire from the linear encoder and aligning the tip of the probe with the first measurement point, operate the remote control device to control the motor and rotate the turntable to the right at a low speed, At the moment when the laser beam emitted from the laser light source on the turntable crosses the probe and the laser beam is incident on the optical sensor of the responding device, infrared light is re-radiated from the LED in the incident direction, and the re-radiated infrared light is rotated. The count values of the first and second up / down counters are stored in the RAM as the angle data and the length data of the first measurement point at the moment when the optical sensor of the base receives light. Next, align the tip of the probe with the second measurement point next to the right, rotate the rotating table to the right, and the laser beam emitted from the laser light source of the rotating table crosses the probe. The infrared rays are re-emitted in the incident direction from the LED at the moment when the laser beam is incident on the optical sensor of the response device, and the first and second up- The count values of the down counter are stored in the RAM as angle data and length data of the second measurement point, respectively. Similarly, the tip of the probe is sequentially aligned with the measurement point on the right, and the angle data and length data for each measurement point are stored in the RAM. When the data on the number of measurement points under the initially set conditions is stored in the RAM, the measurement for one room is completed. And polar coordinate data consisting of these length data and angle data is transmitted to an external calculation processing device such as a personal computer by a signal processing circuit incorporated in a dimension measuring device, and converted into an XY coordinate system, The XY coordinate data is converted into a deviation size from the standard size of the room determined by the standard size and the number of tatami mats. Then, it is displayed or printed by a display device or a small printer attached to the dimension measuring device, or is displayed or printed by a display device or printer connected to an external calculation processing device such as a personal computer.
[0007]
[Problems to be solved by the invention]
  As described above, in the conventional room dimension measurement by the dimension measuring apparatus disclosed in Japanese Patent Laid-Open No. 9-304068, etc., initial setting conditions such as the standard size of the tatami mat and the size of the room (the number of tatami mats) are input. Thus, for example, 12 points are measured in the middle and half space measurement, and 24 points are also set in the booth, and the number of points to be measured (number of measurement points) is set in advance. And it is necessary to measure the measurement points according to the setting, and for example, it is not possible to cope with a measurement method in which the booth measurement is partially performed with the setting of the booth measurement. In other words, as is generally done in the past, the overall dimensions of the room are taken with medium measurements while the number of measurement points is small and the measurement time is short. It is not possible to use a method of taking a fine size. In the conventional method using the dimension measuring apparatus, an error occurs if an attempt is made to make a partial booth measurement with the intermediate measurement setting. In addition, it is inefficient to use the whole room for booth measurement because the number of measurement points increases.
[0008]
  Moreover, in the actual measurement site of a room, there is a possibility that obstacles such as other interior construction tools and materials are placed, and in such a case, there may be a part that cannot be measured partially. Even in such a case, if the measurement location is determined in advance as in the past, skip the location that cannot be measured and move to the next measurement location, or measure the measurement location in the booth next to the measurement location. In some cases, the entire room cannot be measured.
[0009]
  In addition, the conventional measurement above, where the measurement location is determined in advanceMethodThen, as shown in FIG. 2, the position hidden behind the middle pillar and the corner of the room in which the corner pillar is located cannot be measured. Therefore, the dimension measurement of the room having the corner pillar or the middle pillar cannot be performed.
[0010]
  In addition, as described above, the dimension measuring apparatus has a measuring apparatus main body installed in the center of the room and measures the room clockwise, for example, first, the radiation direction of the visible laser beam emitted from the laser beam. It is possible to perform an ambiguous operation such as “nearly the center” or “a little to the left”, such as turning the point slightly to the left of the first measurement point. Because of the specifications, the correspondence between the two-dimensional coordinate system that the measuring device itself has and the two-dimensional coordinate system that indicates the shape of the room are not constant, so length data and angle The calculation method for converting the polar coordinate system composed of data into the XY coordinate system and further converting it into a dimensional representation by deviation from the standard dimension of the room becomes complicated. In other words, the room shape image consisting of the polar coordinate data of the measurement points expressed in length and angle is shifted in the rotation direction with respect to the square representing the reference dimension of the room because the origin of the angle is not determined. Since the polar coordinate data is simply converted into the XY coordinate system under the same conditions, the standard dimensional notation in the tatami mat industryMethodHowever, troublesome calculation is required for conversion to the dimension notation due to deviation from the standard dimension of the room.
[0011]
  Therefore, by measuring the length data and angle data of any measurement point without being restricted by the measurement points and the number of measurement points, such as intermediate measurement or booth measurement, the dimensions of the room are calculated and expressed. It is possible to measure the dimensions of the room where the middle and corner pillars are on a business trip, and the polar coordinate data consisting of the measured length data and angle data can be shifted in the rotational direction relative to the reference dimensions of the room. It is an issue to enable easy conversion to data in a non-XY coordinate system.
[0012]
[Means for Solving the Problems]
  The room is usually rectangular and has four corners and four straight sides. If this is used, it is possible to specify four measurement points corresponding to the corners of the room even if random points including four corners around the room are measured at random. If the point can be specified, it is possible to know the two-dimensional positional relationship such as on which side of the square the other measurement points are located and how far away from the corner.
[0013]
  For this reason, a signal processing circuit such as a microcomputer having a mechanism for accurately measuring and storing length data and angle data as described in JP-A-9-304068, and calculating and processing the measured data is provided. Any measurement location, not a predetermined measurement location, on the premise of using a dimensional measurement device that is configured to transmit or send data to an external calculation processing device such as a personal computer. The geometric positional relationship between the length data and the angle data in the two-dimensional plane is judged by a signal processing circuit such as a microcomputer incorporated in the measuring apparatus or by an external calculation processing device such as a personal computer. Or, if necessary, a person can input additional information to help It is possible to calculate the legal information.
[0014]
  Further, in the measurement of the middle column and the corner column, it is possible to artificially derive the dimensions of the corner column and the middle column that are originally intended to be measured by measuring a place that can be used instead of the place that cannot be measured.
[0015]
  Specifically, the measurement points at the four corners of the room are always included for the entire circumference of the room, and when the length data and the angle data are measured at other measurement points, the number of measurement points is S. , Each measurement point P₁, P₂, P_Three, ... P_SThe three measurement points P where the values of the angle data are adjacent to each other_n-1, P_nAnd P_{n + 1}Pay attention to. Then, assuming that the shape of the room is almost a square as a whole, as shown in FIG._n-1And P_nA straight line passing through and measurement point P_nAnd P_{n + 1}If the straight line passing through is almost perpendicular, the measurement point P_nCan be determined to be a measurement point at the corner of the room, while the measurement point P is measured as shown in FIG._n-1, P_nAnd P_{n + 1}Are aligned on substantially the same straight line, the measurement point P_nCan be determined to be the measurement points of the straight part of the room. Thus, all measurement points P in one room_nBy this method, all the measurement points at the four corners of the room can be determined.
[0016]
  If the four measurement points of the room can be discriminated by this method, the measurement points at the four corners are changed to P as shown in FIG._a, P_b, P_c, P_dAnd the four sides of the room are L_ab, L_bc, L_cd, L_daAs (P_a-P_bThe side formed by L_ab, P_b-P_cThe side formed by L_bc, P_c-P_dThe side formed by L_cd, P_d-P_aThe side formed by L_daAnd other measurement points P_iIt can be easily determined from the magnitude relationship of the “angle data” whether the measurement point is on the side of the side, and the measurement point P with respect to the measurement points at the two corners forming both ends of the side._iCan know where is and how distorted
[0017]
  In addition, when there is a middle pillar or corner pillar, if the laser beam from the measuring device main body does not hit or the wire is bent and the probe cannot be directed toward the measuring device main body, Instead, measure the neighborhood as a measurement point and calculate the position (coordinate) of the corner that cannot be measured or the shadow behind the column itself to be measured, and the size and position of the corner column or center column that you want to measure. Can be calculated.
[0018]
  Also, if the measurement points at the four corners can be specified, the angle coordinate is added to the polar coordinate data composed of the length data and the angle data, and the shape image of the room is rotated as a whole,XY coordinate notationIt is possible to convert to an XY coordinate system that can be easily converted into a dimensional notation.
[0019]
  Therefore, the present invention proposes means for solving the above problems as follows.
[0020]
  That is, in the invention according to claim 1, the dimensions of the room are calculated from the length data and the angle data in the two-dimensional plane of the measurement points at a plurality of surrounding positions measured with reference to a predetermined position in the vicinity of the center of the substantially rectangular room. Indexing,XY coordinate notationMeasurements and calculations for conversion to dimensional notation byMethodIn this case, the length data and the angle data at arbitrary measurement points including four corners around the circumference of the room are measured, and the data are stored in a memory. The angle formed by the two straight lines connecting the measurement point at the center of the measurement point and the measurement points on both sides is calculated to discriminate the measurement points at the four corners, and the polar coordinate data composed of the length data and the angle data is calculated as described above. One of the measurement points at the four corners becomes the origin of the XY coordinates, and one of the measurement points at the other two corners adjacent to each other is converted into XY coordinate data that overlaps the X axis or the Y axis.XY coordinate notationThe XY coordinate data is converted into a deviation dimension from the reference dimension of the room at each prescribed measurement location in association with the prescribed measurement location for the above. In this case, the measurement points at the four corners can be determined based on the length data and the angle data of arbitrary measurement points. When the four corners are specified, polar coordinate data consisting of length data and angle data of all measurement points around the circumference of the room is converted into XY coordinates where one corner of the room overlaps the origin and two sides almost overlap the coordinate axis. The system can be converted in accordance with the rotation direction, and the XY coordinate data is associated with specified measurement points such as intermediate and booth measurements, and the standard dimensions of the room at each specified measurement point It becomes easy to convert to a deviation dimension from.
[0021]
  The invention according to claim 2 is the measurement and calculation for the dimension notation according to claim 1.MethodIn this case, when the central pillar is on a business trip around the room, the measurement points of the central pillar are the four points of both the corners on the projecting side of the central pillar and the measurable positions near both the corners on the wall side. After inputting that it is a measurement point of the middle pillar, measure the length data and angle data of those measurement points, and store the length data and angle data, and at the same time, the measurement points are the measurement of the middle pillar This is to memorize that it is a point, and thereby data necessary for measuring the middle pillar can be obtained.
[0022]
  The invention according to claim 3 is the measurement and calculation for the dimension notation of the room according to claim 1.MethodIn the case where the corner pillar is in a business trip to the corner of the room, three points of the corner on the projecting side of the corner pillar and the measurable position close to both corners on the wall side are the measurement points of the corner pillar, After entering the measurement points of the corner column, measure the length data and angle data of those measurement points and store the length data and angle data. At the same time, the measurement points are the measurement points of the corner column. A certain thing is made to memorize | store in a memory, and the data required for a corner pillar measurement are obtained by this.
[0023]
  The invention according to claim 4 is the measurement and calculation for the dimension notation of the room according to claim 1.MethodWhen the center pillar is traveling around the room, the measurement points at the four corners are discriminated by excluding the data of the measurement points at both corners on the projecting side of the center pillar. When the middle pillar is on a business trip, the measurement points at both corners on the projecting side of the middle pillar are excluded in this manner, thereby facilitating the determination of the measurement points at the four corners of the substantially rectangular room. .
[0024]
  The invention according to claim 5 is the measurement and calculation for the dimension notation of the room according to claim 1.MethodIn this case, when a corner pillar is on a business trip at the corner of the room, the determination of the measurement points at the four corners excludes the measurement point data of the corner on the projecting side of the corner pillar, and From the data of a plurality of measurement points sandwiching the measurement points, a point that becomes the corner of the room at the position of the corner pillar is virtually set as data, and the four points are measured by including the virtually set points as measurement points. The point is discriminated. When the corner pillar is on a business trip, it excludes the data of the measurement points of the corners on the projecting side of the corner pillars in this way, and from the data of a plurality of measurement points sandwiching the corner measurement points of the corner pillars, It is possible to determine the measurement points at the four corners of the substantially quadrangular room by virtually setting the points at the corners of the columns at the column positions as data.
[0025]
  The invention according to claim 6 is the measurement and calculation for the dimension notation of the room according to claim 1.MethodIn this case, after measuring all the measurement points for one room, the measurement points at the four corners are discriminated. The determination of the measurement points at the four corners can be performed after measuring all the measurement points for one room in this way.
[0026]
  The invention according to claim 7 is the measurement and calculation for the dimension notation of the room according to claim 1.MethodThe measurement point which becomes the corner of the room at the time of measurement of each measurement point is determined, and the measurement point of the corner is stored. The determination of the measurement points at the four corners can be sequentially performed when measuring each measurement point in this way.

The polar coordinate data composed of data is converted into XY coordinate data in which one of the measurement points at the four corners is the origin of the XY coordinates and one of the other two measurement points at the adjacent corners is overlapped on the X axis or the Y axis.

DETAILED DESCRIPTION OF THE INVENTION
  The present invention is carried out, for example, using the room dimension measuring apparatus disclosed in Japanese Patent Laid-Open No. 9-304068 proposed by the inventors of the present invention. The dimension measuring device includes a base, a turntable that is rotatably mounted on the base, a rotary encoder that is placed on the turntable and detects a rotation angle of the turntable with respect to the base, A linear encoder that detects the length of the wire or tape that has been pulled out and is placed on the turntable and detects the length of the drawn wire or tape, etc., and is placed on the turntable and lasers in the direction of the turntable A laser light source that emits a light beam, a probe having a sharp tip coupled to the tip of a wire or a tape, and a response device that is provided on the probe and re-radiates the light beam when receiving the laser beam And a storage device for storing the angle data and the length data when the tip of the probe is aligned with the reference point to be measured existing in the pointing direction and the light beam is re-radiated from the response device.
[0032]
  Further, the dimension measuring apparatus incorporates a signal processing circuit shown in FIG. In FIG. 5, 1 is a microcomputer (CPU) that controls the entire apparatus, 2 is the rotary encoder that detects angle data, 3 is the linear encoder that detects length data, and 4 is the rotary encoder 2. 2 is a rotary encoder / counter that counts two-phase pulses generated from the linear encoder 3, and 5 is a linear encoder / counter that counts two-phase pulses generated from the linear encoder 3, and 6 is a ROM that stores a processing program. Is a RAM as the storage device for temporarily storing data, and 8 is an SIO for exchanging data with an external device 9 such as a personal computer or a printer.
[0033]
  As a basic operation when measuring the dimensions of a room using this dimension measuring device, first install the measuring device body in the center of the room and measure the room clockwise (clockwise), for example (counterclockwise) First, the radiation direction of the visible laser beam emitted from the laser beam is directed slightly to the left of the first measurement point, and the standard size of the tatami mat (58, 36, Enter the initial setting conditions such as the size of the room and the size of the room (number of tatami mats). Then, pull out the wire from the linear encoder, align the tip of the probe with the measurement point, operate the remote control device, control the motor to rotate the turntable to the right at a low speed, and turn the laser on the turntable. At the moment when the laser beam emitted from the light source crosses the probe and the laser beam enters the optical sensor of the responding device, the infrared rays are re-radiated from the LEDs in the incident direction, and the re-radiated infrared rays are emitted from the optical sensor of the turntable. The operation of storing the count values of the first and second up / down counters in the RAM as angle data and length data at the moment when the light is received is sequentially performed for each measurement point. After the measurement for one room is completed, polar coordinate data consisting of length data and angle data is transmitted to a signal processing circuit incorporated in the dimension measuring device or to an external calculation processing device such as a personal computer. The XY coordinate system is further converted from the XY coordinate data to the deviation dimension from the standard dimension of the room determined by the standard size and the number of tatami mats, and the display device or small printer attached to the dimension measuring device is used. Display or print, or display or print with a display device or printer connected to an external computer such as a personal computer.
[0034]
  Hereinafter, each example of the embodiment will be sequentially described with reference to the drawings.
[0035]
  (First embodiment)
  The first embodiment includes claims 1 to 6 and 9 to11Measurements and calculations for dimensioning such roomsMethodIt is.
[0036]
  The measurement and calculation procedures in the first embodiment will be described based on the flowcharts (main routine) of FIGS. 6 and 7 and the flowchart (subroutine) of FIG. 8 and with reference to the explanatory diagrams of FIGS. To do. Note that steps S1 to 30 in the following description refer to the steps in the flowcharts of FIGS. 6 and 7, and steps T1 to T10 indicate the steps in the flowchart of FIG.
[0037]
  (Start-Step S5)
  First, the measuring apparatus main body A is installed in the approximate center of the room.
[0038]
  Then, the linear encoder is set to the reference length by turning on the power and attaching the probe to a predetermined position of the measuring device A (step S1), and pressing the confirmation key on the remote control device to 3 is cleared (step S2), and then the "standard size of tatami mat" is input from the remote control device (step S3), and the "room size (number of tatami mats)" is input (step S4). Additional information such as “site name”, “room number”, and “tatami mat type” is input (step S5).
[0039]
  (Steps S6-23)
  First, place the probe (measuring element) on the first measurement point, operate the remote control device to measure, and then, for example, arbitrarily set the next measurement point on the right side and apply the probe. In the same way, the measurement points are sequentially determined clockwise around the room, and arbitrary measurement points around the room are measured so as to always include the measurement points corresponding to the four corners of the room. The CPU 1 checks whether or not there is a new key input from the remote control device (step S6), and proceeds to the next step when there is a new key input. First, the CPU 1 checks whether or not the input is the “RUN” key (step S6). S7). Then, depending on whether or not the current key input is the “driving key”, the process proceeds to different processing as described later. If it is not the “driving” key, it is determined whether or not it is the “cancel” key (step S8). If it is not the “Cancel” key, the process proceeds to another process as will be described later depending on whether the key is a “corner pillar” key (step S9) and whether it is a “middle pillar” key (step S10).
[0040]
  In other words, in this embodiment, when it is necessary to measure the corner column while measuring the room clockwise, the “corner column measurement” switch (“corner column” key) is operated by the remote control device. Then, after making the corner column ready for measurement, three locations around the corner column are continuously measured as shown in FIG. When the “length data” and the “angle data” are stored in the internal memory (RAM 7), the fact that the measurement point is the measurement point of the “corner column” is also stored. Therefore, when the key input is the “corner column” key, a process of inputting that the measurement point of the corner column is measured (set to the corner column measurement mode) is performed (step S18).
[0041]
  If you need to measure the middle column while measuring the room clockwise, you can measure the middle column by operating the “Middle column measurement” switch (“Middle column” key) with the remote control device. After being in the state, as shown in FIG. 10, four locations around the middle pillar are continuously measured. Then, when “length data” and “angle data” are stored in the internal memory, it is also stored at the same time that the measurement point is the measurement point of “middle pillar”. Therefore, when the key input is the “middle column” key, a process of inputting the measurement point of the middle column (set to the middle column measurement mode) is performed before the measurement (step S19).
[0042]
  If the key input is a “cancel” key, the data at the one place measured immediately before is deleted (step S17).
[0043]
  Then, after measuring the measurement points around the entire room, the “complete” switch (“complete” key) is operated with the remote control device to complete the measurement for one room. Is determined (step S11), and if the “complete” key is not input, the measurement is continued and the measurement apparatus main body A is rotating and performing a measurement operation (during measurement). Whether the response signal due to the re-radiation of infrared rays from the probe is present (step S13), and if there is a response signal, the measuring device main body The rotation of A is stopped (step S14), the length data and the angle data are read from the linear encoder 3 and the rotary encoder 2 (step S15), and these are sequentially measured as new measurements. It is stored as the data (step S16).
[0044]
  When the current key input is the “RUN” key, it is checked whether the measuring device main body A is rotating and performing a measurement operation (during measurement) (step S20). Is stopped and the measurement state is released (step S21). When measurement is not being performed, that is, when the measurement is released, rotation is started and the measurement state is set (step S22).
[0045]
  When the measurement points around the entire room are measured, the “complete” switch is operated with the remote controller to complete the measurement for one room. When the “complete” switch is pressed, the CPU 1 performs measurement completion processing for one room (step S23).
[0046]
  And it returns to the step (step S4) which inputs "the size of a room (the number of tatami mats)", measures the next room similarly, repeats the same operation about all the rooms which should be measured, Measurement data is stored for each.
[0047]
  When the key input is the “RUN” key, it is checked whether the measuring apparatus main body A is rotating and performing a measurement operation (during measurement) (step S20). Stop and release the measurement state (step S21). When measurement is not in progress, that is, when the measurement is released, rotation is started and the measurement state is set (step S22).
[0048]
  (Steps S24-30)
  When displaying or printing the measurement result, the “print” key or “communication” key of the remote control device is pressed. Then, the CPU 1 determines whether it is printer printing or PC transmission depending on whether the “print” key is pressed or the “communication” key is pressed (step S24). In the case of printer printing, a room for printing data is selected (step S25), and the measurement data of the room is converted into XY coordinate data, and further, a process for converting into a deviation dimension from the reference dimension is performed. (Step S26), the result is output to the printer and printed (step S27). In the case of transmission to a personal computer, a room to be transmitted to the personal computer is selected (step S28), and the measurement data of the room is converted into XY coordinate data, and further processing for converting into a deviation dimension from the reference dimension is performed. (Step S29), the result is transmitted to the personal computer (Step S30).
[0049]
  Note that the room dimensions converted into the XY coordinate representation and further converted into deviations from the standard dimensions, which are standard room shapes, are output to the printer or personal computer in step S27 or S30 and displayed / printed. It is also possible to display and print the dimension of the actually measured part as it is. However, in general, the dimensions of the measurement points for the intermediate measurement or the booth measurement are displayed in the form of deviation dimensions, including the measurement points by linear interpolation described with reference to FIG. ·Print. In addition, if there is a dimension added by linear interpolation, an accent can be given by means such as reverse display (or printing) or dimension display with parentheses (or printing) in order to emphasize this.
[0050]
  (Step T1)
  The process of converting the measurement data for each room expressed in polar coordinates of “length data” and “angle data” in step S26 and step S29 into XY coordinate data, and further converting it into a deviation dimension from the reference dimension, Follow the steps below.
[0051]
  First, measurement data for one room is extracted, and measurement points at four corners of the room are determined (step T1 in the flowchart of FIG. 8). In this case, the number of measurement points for one room is S, and each measurement point is P as shown in FIG.₁, P₂, ... P_SAnd the last measurement point P_SAnd the first measurement point P₁Handle as if they are connected in a ring. First, the measurement point P for one room₁, P₂, ... P_SMeasuring point P of the corner on the protruding side of the corner post_j(P in the example of FIG. 11₉) And the measuring points of the corners on the projecting side of the middle pillar (P in the example of FIG. 11)₁₃And P₁₄) And the measurement points Q for treating the room as a quadrangle without corner pillars and center pillars as shown in FIG.₁, Q₂, ... Q_t(T represents the measurement point when treated as a quadrangle without a corner column and a center column, and Q_tAnd Q₁Are handled as if they are connected in a ring).
[0052]
  At that time, the measuring point P of the corner column corner_jInstead of the point Q that becomes the corner of the room_kIs set virtually, and as shown in FIG._jMeasurement point P next to the left (measurement order is one before)_j-1And its measurement point P_j-1The measurement point P at the corner which is the farthest measurement point on the same side as the side where the_j0A straight line passing through L_j1And the measurement point P of the corner of the corner column_jMeasurement point P to the right of (measurement order is one ahead)_{j + 1}And its measurement point P_{j + 1}The measurement point P at the corner which is the farthest measurement point on the same side as the side where the_jmA straight line passing through L_j2As those two straight lines L_j1And L_j2The intersection of Q as the corner point of the virtual room_kSet to. And P_j-1Length data L which is the coordinate data of_j-1And angle data θ_j-1And P_j0Length data L which is the coordinate data of_j0And angle data θ_j0And P_{j + 1}Length data L which is the coordinate data of_{j + 1}And angle data θ_{j + 1}And P_jmLength data L which is the coordinate data of_jmAnd angle data θ_jmFrom the geometrical method of finding the intersection of two straight lines, Q_kLength data L which is the coordinate data of_kAnd angle data θ_kCalculate
[0053]
  And the measurement point Q expressed by a square without a corner pillar and a center pillar₁~ Q_tQ₁Search in order from, measuring points Q corresponding to the four corners of the room_p1~ Q_p4Q to determine₁~ Q_tEach of the three measurement points Q in which the angle data values are adjacent and arranged in the order of measurement._k-1, Q_k, Q_{k + 1}About Q_k-1And Q_kA straight line passing through and Q_kAnd Q_{k + 1}The angle ω made by the straight line passing through_k(This ω_kAs shown in FIG._k-1To Q_kThe extension line going to_kTo Q_{k + 1}The straight line toward is the angle formed with the reference line, and the clockwise (right) rotation is expressed as a positive angle). Q_tAnd Q₁Are handled as if they are connected in a ring, Q_t, Q₁, Q₂Is considered to satisfy the condition of three measurement points in which the values of the angle data are adjacent and arranged in the order of measurement.
[0054]
  By the way, since the room is almost square, the angle ω between the two straight lines is_kIs limited to “near 0 degrees” or “near right angle (90 degrees)”. Therefore, for example, as shown in FIG._k> Q for +45 degrees_kIs the corner point of the room, as shown in FIG._k≤ +45 degrees, Q_kCan be determined to be a point on the side of the room, and the measurement point Q_kIt can be easily determined whether or not is a measurement point representing the “corner of the room”.
[0055]
  Therefore, first, k = 1 (Q_k= Q₁)_kQ according to the judgment formula_kIs the measurement point of “the corner of the room”, k is sequentially added (+1), and as shown in FIG._p1And continue to identify the “points in the corners of the room”_p2~ Q_p4And
[0056]
  (Step T2)
  Next, by rotating and translating the entire measurement point, Q_p1Is the origin of the XY coordinates, Q_p22 points Q at the corner of the room to convert from the polar coordinate system to the XY coordinate system (X positive is horizontal right direction and Y positive is vertical downward direction) so that is on the positive X coordinate axis_p1And Q_p2Is searched (step T2 in the flowchart of FIG. 8).
[0057]
  (Step T3)
  And the angle to rotate as a conversion parameter for conversion to XY coordinates
φs and the amount of translation (X_S, Y_S) Is calculated (step T3).
[0058]
  In this case, the angle φs to be rotated is Q_p1Length data is L_p1, The angle data is θ_p1Q_p2Length data is L_p2, The angle data is θ_p2Is obtained by the following equation.
[Expression 1]

[0059]
  Also, the amount of translation (X_S, Y_S) Is obtained by the following equation.
  X_S = L_p1* Cos (θ_p1-Φs)
  Y_S = L_p1* Sin (θ_p1-Φs)
[0060]
  And Q₁~ Q_tAre coordinate data (X, Y) in the XY coordinate system by the following formula:_i(Step T4).
  X_i= L_i* Cos (θ_i−φs) −X_S  (I = 1 to t)
  Y_i= L_i* Sin (θ_i-Φs) -Y_S  (I = 1 to t)
[0061]
  (Steps T5-8)
  Next, each measurement point Q converted to the XY coordinate system._i(X_i, Y_i) Is on the top, bottom, left or right side of the room, and Q₁~ Q_tIt is determined how many measurement points are measured at the measurement points and booth measurement points on the top, bottom, left and right sides of the room (steps T5 to T8).
[0062]
  That is, each measurement point Q_iIndex value i and corner point Q_p1, Q_p2, Q_p3, Q_p4The index values P1, P2, P3, and P4 are compared, and if P1 ≦ i ≦ P2, it is determined as the upper side of the room, and if P2 ≦ i ≦ P3, it is determined as the right side of the room. In the case of P3 ≦ i ≦ P4, the lower side of the room is determined. In the case of P4 ≦ i ≦ P1, the left side of the room is determined.
[0063]
  Then, as shown in FIG.₁~ HU_nx, HR in the middle and booth between the right side₁~ HR_ny, HD between the measurement points in the middle and booth between the lower sides₁~ HD_nx, HL in the middle and booth between the left side₁~ HL_nyAnd set Q₁~ Q_tTo determine which of the measurement points in the middle, booth, and middle of each of the upper, right, lower, and left sides (nx is the number of measurements in the booth in the horizontal direction of the room) , Ny is the number of measurement points in the booth in the vertical direction. If the reference index of HU, HR, HD, HL is an odd number, it is an intermediate measurement point, and if it is an even number, it is a booth medium measurement point).
[0064]
  Measuring point Q on the upper side of the room_i(X_i, Y_i) But HU₁~ HU_nxIn order to determine which of the following, first, the target measurement point Q_iBoth end points (corner points) Q of the side where is located_p1(X_p1, Y_p1) And Q_p2(X_p2, Y_p2), The interval W between the measurement points in each booth is defined by the following equation.
  W = (X_p2-X_p1) / (Nx-1)
[0065]
  Then, HUj having a value of j satisfying the following expression as a reference index is defined as Q_iIt is determined that the measurement location corresponds to.
  X_p1+ W * (j−1) −W / 2 ≦ X_i<X_p1+ W * (j-1) + W / 2
[0066]
  The same processing is performed for the right side, the lower side, and the left side, and in this way, on which side of the room, what number of middle / booth measurement points apply ( Which reference index of HU, HR, HD, and HL is supported) is specified.
[0067]
  In addition, if there is no measurement point corresponding to any of the measurement points of the intermediate measurement among the measurement points actually measured, the data of the measurement point of the intermediate measurement without the corresponding measurement point is Is interpolated from the data actually measured in. The interpolation procedure in this case is as follows.
[0068]
  For example, as shown in FIG. 17, the measurement location HU for measurement between the upper sides of the room._iData (XU_i, YU_i) By interpolation, HU_i(XU_i, YU_iX coordinate value XU_iIs the point Q in the corner of the room_p1(X_p1, Y_p1) And Q_p2(X_p2, Y_p2) Based on the following data:
[Expression 2]

[0069]
  This XU_iFrom the actual measurement points on the upper side of the room_iSearch on both the smaller and larger X-coordinate values,_sn(X_sn, Y_sn), Q_sm(X_sm, Y_sm), The point HU to be interpolated_iY coordinate value YU of_iIs obtained by linear interpolation according to the following equation.
[Equation 3]

[0070]
  (Step T9)
  In this way, at least the measurement location HU corresponding to “intermediate measurement”₁~ HU_nx, HR₁~ HR_ny, HD₁~ HD_nx, HL₁~ HL_nyThen, the XY coordinate data having the dimension display is converted to a deviation dimension in order to represent it by a deviation from the room reference dimension, which is a way of expressing the room dimension when the tatami mat is manufactured (step T9).
[0071]
  Standard dimensions of the room (S_x, S_y) Is calculated by the following formula from the standard size of tatami mats “(58, 36, Honma)” and “room size (number of tatami mats)” input in steps S3 and S4.
  (Horizontal dimension S of the room_x) = U_s* M_x
  (Room vertical dimension S_y) = U_s* M_y
[0072]
  Where U_sIs the standard size of one tatami mat (58 = 5800 厘, 36 = 6000 厘, Honma = 6300 厘), M_xAnd M_yIs the number of tatami mats arranged in the horizontal and vertical directions.
[0073]
  For example, when the standard size of the tatami mat is “58” and the size of the room (the number of tatami mats) is “6 tatami”, the standard size of the room calculated by the above formula is as follows.
  S_x= 5800 * 2 = 11600 厘
  S_y= 5800 * 1.5 = 8700 厘
[0074]
  The above-mentioned HU with respect to the calculated standard room dimensions₁~ HU_nx, HR₁~ HR_ny, HD₁~ HD_nx, HL₁~ HL_nyXY coordinate data is converted into a deviation dimension expressed as a positive dimension (+) for a dimension that protrudes outside the square representing the standard dimension of the room, and a negative dimension (-) for a dimension that enters the room. That is, the measurement location HU on the upper side of the room_i(X_Ui, Y_Ui), (-Y_Ui) Represents the dimension due to deviation, and the measurement point HR on the right side of the room_i(X_Ri, Y_Ri), (X_Ri-S_x) Represents the dimension due to deviation, and the measurement point HD above the lower side of the room_i(X_Di, Y_Di), (Y_Di-S_y) Represents the dimension due to deviation, and the measurement point HLi (X on the left side of the room)_Li, Y_Li) (-X_Li) To represent the dimension due to deviation. FIG. 18 shows an example of the dimension of the room thus converted into the deviation dimension (the example of this figure is an example of the dimension in the case of a 6 tatami room based on the “eighty-eighth” standard. What is expressed is a quadrangle that represents the standard dimensions for a 6-tatami room on a “go-eight” basis.)
[0075]
  (Step T10)
  Next, the dimension and position of the middle pillar are calculated (step T10). The procedure is as follows.
[0076]
  Measurement data P as measured₁~ P_SFrom the four measurement points stored as “medium column measurement” in step S19 at the time of measurement (four measurement points are measured by one center column measurement), these measurement points are shown in FIG. And P_g1, P_g2, P_g3, P_g4And
[0077]
  And two corner points V on the wall side that cannot be measured in the shade of the middle pillar_g1, V_g4The coordinates of P_g1~ P_g4Calculate from Therefore, as shown in FIG._g1And P_g4P for a straight line passing through_g2Draw a straight line vertically from_g1And P_g1And P_g4P for a straight line passing through_g3Draw a straight line vertically from_g4And In this way, two corners on the wall side of the middle column are determined in a pseudo manner, and V_g1(L_g1, Θ_g1), V_g4(L_g4, Θ_g4) Coordinates (L_g1, Θ_g1), (L_g4, Θ_g4).
[0078]
  Further, the dimension w of the four sides of the middle pillar is obtained from the coordinates of the middle pillar thus obtained by a geometric method for obtaining the distance between the two points as shown in FIG.₁, W₂, W_Three, W_FourThen, the position F is calculated with the corner of the room forming the end of one side of the side where the center column is located as a reference point.
[0079]
  (Step T11)
  Next, the dimension of the corner post is calculated (step T11). The procedure is as follows.
[0080]
  Measurement data P as measured₁~ P_SFrom the measurement data stored in step 18 at the time of measurement as “corner column measurement” (three corners are measured by one corner column measurement) are searched, and these measurement points are shown in FIG. And P_h1, P_h2, P_h3And
[0081]
  Then, in the same manner as described with reference to FIG. 13 regarding step T1, as shown in FIG._hpIs set virtually. Then, the coordinates are calculated.
[0082]

[0084]
(Second Embodiment)
  The second embodiment is described in claims 1 to 5 and 7.And 9-11,Measurements and calculations for room dimension notation in particular according to claim 7MethodIt is.
[0085]
  Whereas the previous first embodiment is to measure the measurement points at the four corners after measuring all measurement points for one room, the second embodiment is It is characterized in that a point that becomes a corner measurement at the time of measurement of each measurement point is determined and stored as a corner measurement point.
[0086]
  The flowcharts of FIGS. 6 to 8 are the same as in the case of the second embodiment. Hereinafter, based on these flowcharts, the main points of the measurement and calculation procedures in the second embodiment will be described.
[0087]
  (Start-Step S5)
  First, the measuring apparatus main body A is installed in the approximate center of the room.
[0088]
  Then, the power is turned on, the linear encoder is set to the reference length with the confirmation key of the remote control device (step S1), the counter value of the linear encoder 3 is cleared (step S2), “Standard size” (step S3), “room size (number of tatami mats)” (step S4), and additional information such as “site name” “room number” “tatami mat type” Input (step S5).
[0089]
  (Steps S6-23)
  First, place the probe (measuring element) on the first measurement point, operate the remote control device to measure, and then, for example, arbitrarily set the next measurement point on the right side and apply the probe. Similarly, measurement points are sequentially determined clockwise around the room, and arbitrary measurement points around the room are measured so as to always include measurement points corresponding to the four corners of the room. At that time, the CPU 1 checks whether or not there is a new key input from the remote control device (step S6), and proceeds to the next when there is a new key input, and first checks whether or not the input is a “run” key. (Step S7). Then, the process proceeds to another process depending on whether or not the current key input is the “driving key”. If it is not the “driving” key, it is determined whether or not it is the “cancel” key (step S8). For example, the process proceeds to another process depending on whether it is a “corner pillar” key (step S9) or a “middle pillar” key (step S10).
[0090]
  The processing when the key input is the “corner column” key is the same as that described in the first embodiment, and the corner column measurement mode is set (step S18).
[0091]
  Further, when the key input is the “middle column” key, it is set to the middle column measurement mode in the same manner as described in the first embodiment (step S19).
[0092]
  If the key input is the “cancel” key, the data at the one place measured immediately before is deleted (step S17).
[0093]
  Then, it is determined whether or not the “complete” key is input (step S11). If the “complete” key is not input, the measurement apparatus main body A rotates and performs the measurement operation because the measurement is continued. It is determined whether it is in the middle (measuring) (step S12). If it is being measured, it is checked whether there is a response signal due to infrared radiation from the probe (step S13). The rotation of the measuring apparatus main body A is stopped (step S14). Then, the length data and the angle data are read from the linear encoder 3 and the rotary encoder 2 (step S15), and are sequentially stored as new measurement point data (step S16). Then, returning to step S6, the next measurement point in the clockwise direction is measured in the same manner. In step S16, three consecutive measurement points P are measured._k-2, P_k-1, P_kWhen P is measured, P_k-2And P_k-1A straight line passing through and P_k-1And P_kThe angle ω formed by the two straight lines with the straight line passing through is calculated, and according to the value of ω, when ω> +45 degrees, the measurement point P_k-1Is determined as a corner point of the room, and if ω ≤ +45 degrees, P_k-1Is determined to be a point on the side of the room and the measurement point P_k-1Whether P is a corner point of the room, P_k-1Are stored together with “length data” and “angle data”.
[0094]
  The measurement of the middle column and the corner column is performed by the same operation as in the case of the first embodiment.
[0095]
  When the measurement points around the entire room are measured, the “complete” switch is operated with the remote controller to complete the measurement for one room. When the “complete” switch is pressed, the CPU 1 performs measurement completion processing for one room (step S23).
[0096]
  And it returns to the step (step S4) which inputs "the size of a room (the number of tatami mats)", measures the next room similarly, repeats the same operation about all the rooms which should be measured, Measurement data is stored for each.
[0097]
  When the key input is the “RUN” key, it is checked whether the measuring apparatus main body A is rotating and performing a measurement operation (during measurement) (step S20). Is stopped and the measurement state is released (step S21). When measurement is not being performed, that is, when the measurement is released, rotation is started and the measurement state is set (step S22).
[0098]
  (Steps S24-30)
  When displaying or printing the measurement result, when the “print” key or “communication” key of the remote control device is pressed, the CPU 1 performs printer printing depending on whether the “print” key or the “communication” key is pressed. Or PC transmission (step S24). In the case of printer printing, a room for printing data is selected (step S25), and the measurement data of the room is converted into XY coordinate data, and further, a process for converting into a deviation dimension from the reference dimension is performed. (Step S26), the result is output to the printer and printed (step S27). In the case of transmission to a personal computer, a room to be transmitted to the personal computer is selected (step S28), and the measurement data of the room is converted into XY coordinate data, and further processing for converting into a deviation dimension from the reference dimension is performed. (Step S29), the result is transmitted to the personal computer (Step S30).
[0099]
  In this case as well, the room dimensions converted into the XY coordinate representation and further converted into deviations from the standard dimensions, which are standard room shapes, are output to the printer or personal computer in step S27 or S30, and displayed / displayed. When printing, it is also possible to display and print the dimensions of the actual measurement points as they are, and display and print the measurement point dimensions of the intermediate measurement or booth measurement in the form of deviation dimensions. It is. Further, in order to emphasize the dimension added by linear interpolation, it is possible to add an accent by means such as reverse display (or printing) or parenthesized dimension display (or printing).
[0100]
  (Step T1)
  Processing for converting the measurement data for each room expressed in polar coordinates of “length data” and “angle data” into XY coordinate data, and further converting it into a deviation dimension from the reference dimension (step S26, step S29) Follow the steps below.
[0101]
  First, measurement data for one room is extracted, and measurement points at four corners are determined (step T1). However, in this second embodiment, since each measurement point is stored while determining whether it is a measurement point that hits the corner of the room at the time of measurement, if there is no corner pillar, the point Q at the four corners of the room is stored._p1, Q_p2, Q_p3, Q_p4Has already been identified. When there is a corner pillar, the measurement point P for one room₁, P₂, ... P_SMeasuring point P of the corner on the protruding side of the corner post_jMeasurement points Q to exclude the measurement points at both corners on the projecting side of the center column and the center column, and to treat the measurement points as a square without a corner column and a center column₁, Q₂, ... Q_tReplace with At that time, the corner point Q of the virtual room is placed at the corner post as in the first embodiment._kSet.
[0102]
  (Step T2)
  Next, by rotating and translating the entire measurement point, Q_p1Is the origin of the XY coordinates, Q_p22 points Q at the corner of the room to convert from the polar coordinate system to the XY coordinate system (X positive is horizontal right direction and Y positive is vertical downward direction) so that is on the positive X coordinate axis_p1And Q_p2Is searched (step T2).
[0103]
  (Step T3-8)
  As in the first embodiment, the angle φs to be rotated and the amount of translation (X_S, Y_S) (Step T3) and Q₁~ Q_tAre all coordinate data in the XY coordinate system (X_i, Y_i) (Step T4), and then each measurement point Q converted to the XY coordinate system_i(X_i, Y_i) Is on the top, bottom, left or right side of the room, and Q₁~ Q_tIt is determined how many measurement points are measured at the measurement points and booth measurement points on the top, bottom, left and right sides of the room (steps T5 to T8).
[0104]
  In addition, the data of the measurement point of the intermediate measurement while there is no corresponding measurement point is obtained by interpolation.
[0105]
  (Step T9)
  In this way, at least the measurement location HU corresponding to “medium measurement”₁~ HU_nx, HR₁~ HR_ny, HD₁~ HD_nx, HL₁~ HL_nyThe data converted into the XY coordinates is converted into a deviation dimension from the reference dimension of the room as in the first embodiment (step T9).
[0106]
  (Steps T10 and 11)
  Next, in the same procedure as in the first embodiment, the size and position of the middle column are calculated (step T10), and the size of the corner column is calculated (step T11).
[0107]
(Third embodiment)
  The third embodiment is claimed in claim 1.And 8-11,Measurement and calculation for room dimension notation according to claim 8 in particularMethodIt is.
[0108]
  In the first and second embodiments, when measuring the corner column / center column, the “corner column measurement” and “center column measurement” switch is pressed with the remote controller immediately before the measurement, so that the measurement device has the corner column / center column. Whereas the presence of a column was input, the third aspect of the present invention provides a geometric positional relationship between measurement points without inputting the “corner column measurement” and “center column measurement” switches from the remote control. Therefore, the configuration (claim 8) is capable of automatically recognizing the presence of corner pillars and middle pillars.
[0109]
  The measurement and calculation procedures in the third embodiment are based on the flowcharts (main routines) shown in FIGS. 26 and 27 and the flowcharts (subroutines) shown in FIGS. 28 and 29, and the explanatory diagrams shown in FIGS. The description will be given with reference. In the following description, steps E1 to E27 indicate steps in the flowcharts of FIGS. 26 and 27, and steps P1 to P21 indicate steps in the flowcharts of FIGS.
[0110]
  (Start-Step E5)
  First, the measuring apparatus main body A is installed in the approximate center of the room.
[0111]
  Then, the power is turned on, the linear encoder is set to the reference length with the confirmation key of the remote control device (step E1), the counter value of the linear encoder 3 is cleared (step E2), "Standard size" (step E3), "room size (number of tatami mats)" (step E4), additional information such as "site name" "room number" "tatami mat type" Input (step E5).
[0112]
  (Steps E6-20)
  Then, in preparation for the measurement of one room, the initial setting is made (step E6), the probe (measurement element) is first applied to the first measurement point, the remote control device is operated, and then, for example, The next measurement point is arbitrarily determined on the right side, and the probe is applied to perform measurement. Similarly, measurement points are sequentially determined clockwise around the room so that the measurement points corresponding to the four corners of the room are always included. Measure any measurement point around the room. At that time, the CPU 1 checks whether or not there is a new key input from the remote control device (step E7), and proceeds to the next step when there is a new key input. First, the CPU 1 checks whether or not the input is the “RUN” key. (Step E8). Then, the process proceeds to another process depending on whether or not the current key input is the “driving key”. If it is not the “driving” key, look at the “cancel” key (step E9), and the “cancel” key must be used. If it is, the process proceeds to the determination (step E10) as to whether or not the key is “complete”.
[0113]
  If the key input is the “Cancel” key, the data at the one place measured immediately before is deleted (step E16).
[0114]
  Proceeding to the determination of whether or not the “complete” key has been input (step E10), and if the “complete” key has not been input, the measurement apparatus main body A is rotating and performing the measurement operation because the measurement is continued. Whether or not (measurement is in progress) is determined (step E11). If measurement is being performed, it is determined whether or not there is a response signal due to infrared radiation from the probe (step E12). Sometimes the rotation of the measuring device main body is stopped (step E13). Then, the length data and the angle data are read from the linear encoder 3 and the rotary encoder 2 (step E14), and are sequentially stored as new measurement point data (step E15). Then, the process returns to step E7, and the next measurement point in the clockwise direction is measured in the same manner.
[0115]
  When it is necessary to measure the corner column, unlike the first and second embodiments, the corner column can be measured only by pressing the “corner column” key, without making the corner column ready for measurement. As shown in Fig. 3, three places around the corner post are measured. Further, when it becomes necessary to measure the middle pillar, simply measure the four places around the middle pillar as shown in FIG.
[0116]
  When the measurement points around the entire room are measured, the “complete” switch is operated with the remote controller to complete the measurement for one room. When the “complete” switch is pressed, the CPU 1 performs measurement completion processing for one room (step E20).
[0116]
  And it returns to the step (step E4) which inputs "the size of a room (the number of tatami mats)", measures the next room similarly, repeats the same operation about all the rooms which should be measured, Measurement data is stored for each.
[0117]
  Further, when the key input is the “run” key, it is checked whether the measuring apparatus main body A is rotating and performing a measurement operation (during measurement) (step E17). Is stopped and the measurement state is released (step E18). When measurement is not being performed, that is, when the measurement is released, rotation is started and the measurement state is set (step E19).
[0118]
  (Steps E20 to 27)
  When displaying or printing the measurement result, when the “print” key or “communication” key of the remote control device is pressed, the CPU 1 performs printer printing depending on whether the “print” key or the “communication” key is pressed. Or PC transmission (step E21). In the case of printer printing, a room for printing data is selected (step E22), and the measurement data of the room is converted into XY coordinate data, and further, a process for converting into a deviation dimension from the reference dimension is performed. (Step E23), the result is output to the printer and printed (step E24). In the case of transmission to a personal computer, a room to be transmitted to the personal computer is selected (step E25), and the measurement data of the room is converted into XY coordinate data, and further processing for converting into a deviation dimension from the reference dimension is performed. (Step E26), the result is transmitted to the personal computer (Step E27).
[0119]
  In this case as well, the room dimensions converted into the XY coordinate representation and further converted into deviations from the standard dimensions of the standard room shape are output to the printer or personal computer at step E24 or step E27, and displayed / displayed. When printing, it is also possible to display and print the dimensions of the actual measurement points as they are, and display and print the measurement point dimensions of the intermediate measurement or booth measurement in the form of deviation dimensions. It is. Further, in order to emphasize the dimension added by linear interpolation, it is possible to add an accent by means such as reverse display (or printing) or parenthesized dimension display (or printing).
[0120]
  (Step P1)
  Processing for converting the measurement data for each room expressed in polar coordinates of “length data” and “angle data” into XY coordinate data and further converting it into a deviation dimension from the reference dimension (step E23, step E26) Follow the steps below.
[0121]
  In the third embodiment, before the polar coordinate data consisting of “length data” and “angle data” is subjected to XY coordinate conversion, processing for specifying the measurement points of the corner column and the middle column is performed. Then, first, measurement data for one room is extracted (step P1).
[0122]
  (Step P2)
  First, in order to perform a process of dividing each measurement point into a linear part and a non-linear part (including the corner, corner pillar, and middle pillar of the room) of the room, first, the first measurement point P_k(K = 1) is specified (step P2).
[0123]
  (Step P3)
  And the first measurement point P_kStarting from (k = 1), any measurement point P_k, Measuring point P before and after_k-1(Last measurement point) and P_{k + 1}From the measurement data (for example, right next to the clockwise direction), the measurement point P_kRoom bending at ω_k(P_k-1And P_kAnd a straight line connecting_kAnd P_{k + 1}The angle formed by the straight line connecting_kIs -α <ω for a predetermined threshold α_k<Depending on whether or not α is satisfied, as shown in FIG. 30 (a), the measurement point Pk is a measurement point of the linear portion of the room, or as shown in FIG. 30 (b), the measurement of the non-linear portion is performed. It is determined whether it is a point (step P3).
[0124]
  -Α <ω_k<If α is satisfied, P_kIs the measurement point of the straight line portion (ωk is around 0 degree). Usually, as shown in FIG. 31, the degree of distortion of the straight part of the room is half the distance (the length of one side of the semi-tatami mat: about 3 scales = 909 mm), and the distortion is less than 5 minutes (about 15 mm). If there is almost anything, by setting α to about 1 degree, it can be determined whether it is a straight portion or a non-linear portion. However, in practice, in order to make a reliable determination even when the distortion is slightly large, α is set to about 3 to 10 degrees with some allowance.
[0125]
  (Step P4)
  And ω_k-Α <ω_k<If α satisfies the measurement point P_kIs determined as a point on the straight line and stored (step P4).
[0126]
  (Step P5)
  Also, ω_k-Α <ω_k<If α is not satisfied, the measurement point P_kIs a point of a non-linear portion, and in order to further determine whether it is a corner point of a room or a measuring point of a corner pillar / center pillar, first, the next measuring point P in the measurement order_{k + 1}Angle of turn at ω_{k + 1}The magnitude relationship between and α is observed (step P5).
[0127]
  (Step P6)
  And ω_{k + 1}In the case of> −α, as shown in FIG._kIs determined to be a corner point of the room and stored (step P6).
[0128]
  (Step P7)
  Also, ω_{k + 1}In the case of ≦ −α, as shown in FIG._kIs the first measurement point of the corner column or the middle column, and in order to further check whether the measurement point is the measurement point of the corner column or the measurement point of the middle column, the next measurement point P in the measurement order_{k + 2}Angle of turn at ω_{k + 2}(Step P7).
[0129]
  (Step P8)
  And ω_{k + 2}If ≧ 0, as shown in FIG._kIs determined as the first measurement point of the corner post, and P_{k + 1}To the second measurement point, P_{k + 2}Is the third measurement point (step P8).
[0130]
  (Step P9)
  Also, ω_{k + 2}If <0, as shown in FIG._kIs determined as the first measurement point of the middle pillar, and P_{k + 1}To the second measurement point, P_{k + 2}The third measurement point, P_{k + 3}Is the fourth measurement point (step P9).
[0131]
  (Step P10)
  Thus, when measurement is completed for a certain k, all measurement points P are measured.₁, P₂, ... P_SFor each measurement point in the same way, k is set to 1 in order to specify whether it is a point on the straight line of the room or the “corner of the room”, “corner pillar” or “middle pillar” of the non-linear part. Add (step P10).
[0132]
  (Step P11)
  Then, it is checked whether or not measurement points have been specified for all measurement points k (step P11). If there are measurement points that have not yet been specified, the above processing is repeated.
[0133]
  (Step P12)
  When all the measurement points have been identified, the XY conversion process starts.
[0134]
  In the case of the third embodiment, the measurement points of “the corner of the room”, “corner column”, and “middle column” have already been specified. And the point Q at the four corners of the room when there is no corner pillar_p1, Q_p2, Q_p3, Q_p4Has been identified. When there is a corner pillar, the measurement point P for one room₁, P₂, ... P_SMeasuring point P of the corner on the protruding side of the corner post_jMeasurement points Q to exclude the measurement points at both corners on the projecting side of the center column and the center column, and to treat the measurement points as a square without a corner column and a center column₁, Q₂, ... Q_tReplace with At that time, the corner point Q of the virtual room is placed at the corner post as in the first embodiment._kSet.
[0135]
  Therefore, first, by rotating and translating the entire measurement point, Q_p1Is the origin of the XY coordinates, Q_p22 points Q at the corner of the room to convert from the polar coordinate system to the XY coordinate system (X positive is horizontal right direction and Y positive is vertical downward direction) so that is on the positive X coordinate axis_p1And Q_p2(Step P12).
[0136]
  (Steps P13-18)
  As in the first embodiment, the angle φs to be rotated and the amount of translation (X_S, Y_S) (Step P13), Q₁~ Q_tAre all coordinate data in the XY coordinate system (X_i, Y_i) (Step P14), and then each measurement point Q converted to the XY coordinate system_i(X_i, Y_i) Is on the top, bottom, left or right side of the room, and Q₁~ Q_tIt is determined how many measurement points are measured at the measurement points and booth measurement points on the top, bottom, left and right sides of the room (steps P15 to P18).
[0137]
  In addition, the data of the measurement point of the intermediate measurement while there is no corresponding measurement point is obtained by interpolation.
[0138]
  (Step P19)
  In this way, at least the measurement location HU corresponding to “medium measurement”₁~ HU_nx, HR₁~ HR_ny, HD₁~ HD_nx, HL₁~ HL_nyAs in the first embodiment, the data converted into the XY coordinates is converted into a deviation dimension from the reference dimension of the room (step P19).
[0139]
  (Steps P20 and 21)
  Next, in the same procedure as in the first embodiment, the size and position of the middle column are calculated (step P20), and the size of the corner column is calculated (step P21).
[0140]
(Fourth embodiment)
  In the first to third embodiments, the dimensions of the measured rooms are all represented by the dimensions at the “intermediate measurement position” and the “intermediate measurement position”, but in the fourth embodiment, Rather than assigning the measurement points to “intermediate measurement position” and “booth measurement position”, the coordinate value (X_n, Y_n) (The unit is arbitrary) is displayed and printed.
[0141]
  That is, as shown in FIG. 36, arbitrary measurement points including four corners are measured for the circumference of the room. Then, polar coordinate data composed of length data and angle data of each measurement point, one of the measurement points at the four corners becomes the origin of the XY coordinates, and the measurement points at the other two adjacent corners overlap on the X axis and the Y axis. It converts into XY coordinate data, and describes the dimensions of the room in the form of the XY coordinate data.
[0142]
  According to this method, it is possible to measure a roughly accurate shape of a room by measuring only the areas where the distortion is particularly large (vertices and valley points of distortion irregularities) and the four corners of the room among the sides of the room. .
[0143]
(Fifth embodiment)
  In the first to fourth embodiments, the measurement order of each measurement point is to measure clockwise or counterclockwise in order from the first measurement point, whereas this fifth embodiment. So, as long as it contains the four corner points of the room (if there is a corner pillar, you can set a virtual corner point), the measurement order of each measurement point is basically irrelevant It is. In this case, after measuring all the measurement points for one room, the value of the angle data at each measurement point is viewed, and the measurement points are rearranged in ascending order (clockwise or counterclockwise). At this time, the angle data is handled in such a way that a change between 359 degrees and 0 degrees is also regarded as ascending order. Doing so is equivalent to measuring clockwise or counterclockwise.
[0144]
(Sixth embodiment)
  In the first to fifth embodiments, everything from the measurement to the conversion, display and printing of the dimensions is performed by the dimension measuring apparatus, whereas in the sixth embodiment, only the measurement of each measurement point is performed. Is sent to and input to an external processing device such as a personal computer in the polar coordinate format, and XY conversion or Convert to deviation, display and print.
[0145]
【The invention's effect】
  According to the present invention, by measuring the length data and the angle data of an arbitrary measurement point without being restricted by the predetermined measurement points and the number of measurement points such as intermediate measurement or booth measurement, the dimensions of the room can be determined. It can be calculated and written, and the dimensions of the room where the center and corner pillars are on a business trip can be easily measured. Polar coordinate data consisting of measured length data and angle data can be rotated with respect to the standard dimensions of the room. It can be easily converted into XY coordinate system data without any deviation.
