DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates relates to a building map creation method and apparatus <br/>, in particular, the building map creation method and apparatus <br/> articles registration application drawings.

In this building map creation method, it is necessary that a building map can be easily created using a land map provided at a registry office.

[0003]

2. Description of the Related Art At the request of a client, a land and house surveyor creates a building drawing of a registration application drawing. In this case, the building drawing of the registration application drawing is created using the building shape data as the design data, the distance data between the building and the land outline as the surveying data, and the land shape drawing provided at the registry office. .

[0004] As three graphic elements to be arranged in a building drawing which is a sketch of a building and land, there are a shape of the first floor of the building, a shape of the land, and a dimension line indicating a distance between the building and the outline of the land.
The building shape data has no error because it is based on the design drawing. For the distance between the building and the land outline, numerical values of three actually measured locations are used.

[0005] For the shape of the land, a drawing is originally created based on the survey data, but a map provided at a registry office is used due to the budget of the client.

Conventionally, a building system has been used to create and output a building map by inputting data, commands, and the like. In this drawing system, first, data on the shape of a building, which is design data, the position of an end point of a building to which three dimension lines are to be attached, and dimension values, which are survey values, are input.

[0007] In addition, a shape map of the land provided at the registry office is input by a digitizer or the like. Thereafter, the drawing system moves and rotates the land shape diagram by the operation of the operator, and joins the end points of the three dimension lines of the building shape diagram and the outline line of the land.

[0008]

In the conventional drawing system, the operator manually moves and rotates the land shape map,
The end points of the three dimension lines of the shape diagram of the building are joined to the outline of the land. However, there is a problem in that it takes time and effort to join such that the end points of the dimension lines do not protrude from the outline of the land or a gap is formed.

The present invention has been made in view of the above points, and it is possible to easily create a building diagram by automatically joining the end points of the dimension lines of the building shape diagram and the land shape diagram. The purpose is to provide a building drawing creation method that can be used.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a flowchart showing a processing procedure of a building drawing processing according to an embodiment of the present invention. Also, FIG.
1 shows a configuration diagram of a drawing system to which the present embodiment is applied. FIG.
Is a processing device 1 for executing a drawing process.
1, an input device 12 such as a keyboard for an operator to input commands, numerical values, etc., a digitizer device 15 for inputting data of drawings, a display device 14 such as a CRT display for displaying building shapes, characters, etc. A pointing device (mouse or the like) 13 for designating a cursor position on the display device 14, an output device 16 for printing out a drawing of a drawing result, and the like.

As shown in FIG. 1, in the drawing process, first,
Input floor shape data of each floor of the building (Step 2)
01). Next, among the input floor shapes of each floor, the data of the floor shape of the first floor is automatically referred to, and the shape diagram of the floor shape of the first floor is set as the shape diagram of the building for the building map (step 20).
2). FIG. 3 shows an example of a building shape diagram. The building shape diagram 21 of FIG. 3 is a shape having six vertices A to F.

Next, the digitizer device 15 is used to input a shape map of the land provided at the registry (step 203).
FIG. 4 shows an example of an input land shape map. The land shape diagram 22 of FIG. 4 includes four vertices H ₀ , I ₀ , J ₀ , and K _0.
The shape has It should be noted that the shape of the land provided at the registry office has low accuracy and may be different from the actual shape of the land.

Next, when the distance data from the end point of the building to the outline of the land, obtained by surveying at three places, is input as the dimension value of the dimension line, the dimension value is stored and the display device is displayed. A building shape diagram is displayed on the screen 14 and dimension lines are temporarily displayed (step 204). Since the length of the dimension line may be corrected later, the display of the dimension line here is a provisional display.

FIG. 5 shows a display example of an outline drawing of a building and a dimension line in which dimension values are inputted. The shape diagram of the building is indicated by a solid line, and the dimension line is indicated by a broken line. In addition,
On the actual display device 14, only the shape diagram of the building and the dimension line are displayed, but for convenience of description, symbols indicating the vertices, the end points of the dimension line, and the like are described. The same applies to the display examples in the subsequent drawings.

In the example of FIG. 5, the distance from the vertex A of the building to the outline of the land measured to the left in the figure is input as the dimension value of the dimension line m1. Further, the distance from the vertex A of the building to the outline of the land measured upward in the drawing is input as the dimension value of the dimension line m2. The distance from the vertex B of the building to the outline of the land measured upward in the figure is input as the dimension value of the dimension line m3. Here, the end points of the dimension lines m1, m2, and m3 extending from the end points A and B of the building are denoted by P ₁ and P ₁ , respectively.
Q ₁ and R ₁ .

As a method of inputting the dimension value of the dimension line, for example, on the screen of the display device 14, after the cursor is positioned at the vertex of the building being displayed, the dimension value of the dimension line is inputted, and then the dimension value is inputted. Specify the direction of the line with the arrow keys.

The input dimension value of the dimension line is composed of dimension value display data for displaying the dimension value as a numerical value in the building drawing, and dimension line display data corresponding to the length of the dimension line to be displayed. Is stored separately.

Next, in accordance with the designation of the operator, the end points of the dimension lines of the building shape diagram and the outlines of the land shape diagram are automatically joined (step 205). When joining,
With the building shape diagram and the land shape diagram displayed on the screen of the display device 14, the operator selects one of the three dimension lines with a mouse or the like, and performs the above selection. Select the outline of the land that joins the dimension lines with a mouse or the like.
Similarly, for the other two dimension lines, the outline of the land to be joined is selected. When the outline of the land that joins each dimension line is specified, the drawing system automatically moves and / or rotates the land shape drawing based on the building shape drawing, The end points of the dimension line of the building shape map and the outline of the land shape diagram are joined.

As described above, since the figure of the building and the dimension line are automatically joined to the shape of the land, the operator may be troublesome to join, unlike the conventional drawing system. Absent.

At the time of this joining, three dimension lines 3
If the two endpoints cannot be joined together,
One end point is joined, and the other end point is set so that the distance from the outline of the land to be joined is minimized. One end point of the dimension line that could not be joined can be completely joined by a land shape changing process and a building drawing arrangement process described later.

As a method of determining the priority, for example, the end points of the two dimension lines previously input when the dimension lines are input are prioritized. Alternatively, a method may be used in which the operator specifies two priority dimension lines.

As a processing method in a case where the three end points of the three dimension lines cannot be joined together, a method of making the three end points of the dimension line evenly approach the outline of the land can be considered. In some cases, the processing time is significantly longer than the method of preferentially joining the dimension lines of a book.

FIG. 6 is a diagram showing the shape of the land shown in FIG.
In the case of the building shape diagram and the dimension line shown in FIG. 1, a diagram in which the building and dimension line diagram and the land shape diagram are joined is shown. In the example of FIG. 6, the line segment H _{1 is used} as the outline of the land joining the dimension line m1.
K ₁ is specified, the line H ₁ I ₁ is designated as the outline of the land joining the dimension line m @ 2, m3.

In the drawing system, the original land shape diagram 22 (vertices H ₀ , I ₀ , J ₀ , K ₀ ) shown in FIG. 4 is automatically obtained.
The translated and rotated, as shown in FIG. 6 are joined dimension line m1, m @ 2, m3, the end points P _1, Q _1, R ₁ of the outline of the land. In the bonding state, the vertex of the shape view of land, respectively, are moved to the vertex _{H 1, I 1, J 1} , K 1.

In the example shown in FIG. 4, the line segment H ₀ I ₀ of the input original land shape diagram rises to the right in FIG. 4 in comparison with the actual land due to the accuracy of the drawing. I have. For this reason,
As shown in FIG. 6, in a state where the outline of the land is joined to the end point of the dimension line, the shape diagram 22 of the land is rotated clockwise.

After the joining processing of the building and dimension line drawing and land shape drawing in step 205 described above is completed, the drawing system determines whether or not a command to complete joining has been input by the operator (see FIG. 4). Step 206).

The operator confirms on the screen of the display device 14 the result of joining the above-described building and dimension line diagram with the land shape diagram. As a result of this check, if there is no problem in the joining state of the end points of the dimension line, the angle of the land shape map with respect to the building shape map, or the like, the operator inputs a command to complete the joining. If a joining completion command is input, step 209 is executed.
To perform the layout processing of the building diagram.

As a result of checking the joining state of the figure of the building and the dimension line and the figure of the land, the joining state of the end points of the dimension line and the land to the figure of the building were determined in relation to the accuracy of the input land figure. If there is a problem with the angle or the like of the shape map, the shape map of the land can be changed. In this case, the operator
Enter a command to indicate that joining has not been completed.

When the operator inputs a command indicating that joining has not been completed, the drawing system changes the land shape diagram (step 207). The drawing system uses a vertex move command to move the position of the land vertex, a vertex add command to add a new land vertex, and a vertex delete command to delete the existing vertex to change the land shape map. Is provided. The operator can change the land shape map so as to approximate the actual land shape using the above command.

For example, when moving the vertex of the land, the operator selects the vertex move command, and then selects the display device 1.
After selecting the vertex to be moved on the screen of step 4 with a mouse or the like,
Specify the destination of the selected vertex with a mouse or the like. Thereby, the vertex is moved, and the line segment passing through the vertex before the movement is changed to pass through the moved vertex. The operator uses the above command to bring the land shape map closer to the actual land shape, in the same sense as handwriting,
Can be easily changed.

In this case, the figure shown in FIG. 6 in which the figure of the building and the dimension line and the figure of the land are joined together is shown in FIG.
The following describes an example in which there is a problem with the angle of the land shape diagram 22 with respect to FIG. In the actual land shape, the line segment I ₁ J ₁
Is vertical in FIG. 6, the line segment K ₁ J ₁ is horizontal, and
It is assumed that the line segment H ₁ K ₁ has a smaller angle with the line segment H ₁ I ₁ .

FIG. 7 is a diagram in which the land shape diagram of FIG. 6 is changed so as to approximate the actual land shape. In FIG.
Segment I ₁ J ₂ is vertical in FIG. 7, as the line segment K ₁ J ₂ is horizontal, using the vertex movement command, and moves the original vertex J ₁ in FIG. 6 to the vertex J ₂ I have. The line segment H ₁ K ₂
, So that the angle formed by the line segment H ₁ I ₁ is smaller,
Moving the vertex K ₂ the original vertex K ₁ in FIG. 6 in the horizontal direction. By moving the vertices J ₁ and K ₁ , the land shape diagram 22 can be actually brought close to the land shape.

However, as a result of changing the line segment H ₁ K ₁ to the line segment H ₁ K ₂ , the end point P ₁ of the dimension line m ₁ slightly protrudes from the land outline. Such a slight protrusion of the dimension line or a gap between the contour line of the land and the dimension line is automatically adjusted at the stage of a building drawing arrangement process described later.

After the process of changing the land shape map in step 207, the drawing system determines whether or not a command instructing another joining process has been input (step 2).
08). At the stage where the change of the land shape map is completed, the operator confirms the joining state between the building and dimension line diagram and the land shape diagram. As a result of this check, if the end point of the dimension line is significantly protruded from the land outline, a gap is formed, or if the angle of the land outline is significantly different from the actual one, By inputting the command to instruct the joining, the joining process of the building and the dimension line diagram and the land shape diagram can be performed again.

In the drawing system, when a command for instructing the joining process again is input by the operator, the process returns to step 205, and the joining process of the above-mentioned drawing of the dimension line of the building and the shape of the land is performed. Execute

If there is no problem as a result of checking the joining state between the dimension line of the building and the shape diagram of the land, the operator inputs a command instructing that the joining is not necessary again. In this case, the drawing system proceeds to step 209 and executes a building drawing arrangement process.

In the example of FIG. 7, since the re-joining is not necessary, after the change of the land shape map is completed, step 209 is executed.
To perform the layout processing of the building diagram.

In the process of arranging the building diagram, the end points of the dimension lines are completely joined to the outline of the land, and thereafter, the building diagram created by adding annotations and the like is arranged on the registration application diagram (step 209).

In the process of arranging the building diagram, first, the joining state between the end point of the dimension line of the building and the outline of the land is examined. As a result, if the end points of the building dimension line are not completely joined to the land outline, the dimension line length is automatically corrected so that the dimension end point is completely connected to the land outline. Join.
For this reason, even if there are some protrusions and gaps in the joints at the stage where the drawing of the building and the dimension line and the land shape diagram are joined in the processing up to step 208, the building drawing is arranged at the stage of processing. Automatically, you can create a building diagram where the joints are completely joined.

When correcting the length of the dimension line,
Only the dimension line display data stored when the dimension value of the dimension line is input in step 204 is changed, and the dimension value display data is not changed. For this reason, the dimension line can be completely joined to the land shape map without changing the dimension value displayed on the building map and keeping the numerical value of the survey result.

FIG. 8 is a diagram in which the drawing of the building and the dimension line shown in FIG. 7 and the shape diagram of the land are joined, and the length of the dimension line is corrected to be completely joined. In FIG. 7, the dimension line m
The end point P1 of ₁ slightly protrudes from the outline of the land. In the placement processing of building diagrams, by shortening the length of the dimension line m1, it joins the end points P ₂ after the change of the dimension line m1 completely outline of land.

After the modification of the dimension lines, in the processing of arranging the building diagram, commentary characters such as addresses, dimension values, roads, waterways, etc. are added to the diagram in which the building and dimension line diagrams and the land shape diagram have been joined. And create a building diagram. The created building drawing is placed on the registration application drawing.

FIG. 9 shows an example of a registration application diagram in which a building diagram is arranged. The drawing in FIG. 9 is an example of a drawing printed out by the output device 16 after confirming the completed state of the registration application drawing on the screen of the display device 14. In FIG. 9, a building diagram 23 based on a diagram in which the diagram of the building and the dimension line shown in FIG. 8 and the shape diagram of the land are joined is arranged in the dashed circle. The dimension lines are indicated by broken lines, and the numerical values of the dimension values, 3.0 and 6.0, are displayed near the dimension lines. In addition, 10-
1, 10-2, 10-3 and the annotation character "road" are displayed.

In the registration application diagram, a plan view of each floor of the building is displayed in addition to the building diagram. In FIG. 9, a plan view of the first floor and a quadrature table for indicating the floor area are displayed.

FIG. 10 shows another example of a diagram obtained by joining a diagram of buildings and dimension lines with a diagram of land shape. In the example of FIG. 10, three dimension lines m4, m5, and m6 are attached to the building shape diagram 21 according to the input dimension values. Here, it is assumed that, among the dimension lines, the dimension lines m4 and m5 have a higher priority.

The land shape map 32 input by the digitizer device 15 is converted into a dimension line m4 by parallel movement in the joint processing of the building and dimension line diagram and the land shape diagram.
End point S ₁ of which is joined to the end point T ₁ of the dimension line m5.
Accuracy of the relationship between outline drawing 32 of the input land endpoint U ₁ of lower priority dimension line m6 are slightly protruding from the outline of the land. Also, among the outlines of the land, the line segment L ₁ M
_In FIG. 10, “ _1” is ascending to the right as compared with the actual land shape.

FIG. 11 is a diagram in which the land shape map shown in FIG. 10 is changed to match the actual land shape in the land shape map change processing. In FIG.
The outline L ₁ M ₁ of the land is horizontal in FIG.
And, as the end point U ₁ of the dimension line m6 is joined to the outline of the land, with a vertex movement command to move the original vertices M ₁ to the vertex M _2, the original vertices N ₁ to the vertex N ₂ I'm moving.

At the stage when the change of the land shape diagram has been completed, the end point T ₁ of the dimension line m5 slightly protrudes from the outline of the land. The protrusion of the dimension line can be joined again by executing the joining process of the drawing of the dimension line of the building and the shape diagram of the land.

FIG. 12 is a diagram corresponding to the diagram shown in FIG.

As described above, in the present embodiment, the end point of the dimension line of the building shape diagram and the land shape are automatically moved by moving and rotating the land shape diagram based on the building shape diagram. The operator can easily create the building drawing without joining the joining work with the drawing, because the joining is not troublesome.

Further, since there is a function of changing the shape of the land using commands for moving a vertex, adding a vertex, and deleting a vertex, even if there is a problem in the accuracy of the shape of the land, the shape of the land can be changed. Can be easily changed to approximate the shape of the actual land.

Also, in the process of arranging the building diagram, the length of the dimension line can be automatically corrected and the dimension line can be completely joined to the land shape diagram, so that the building diagram can be more easily created. can do.
