  Hereinafter, an embodiment of the present invention will be described.

  FIG. 1 is a block diagram illustrating the system configuration of the present embodiment. In FIG. 1, a server device 1 implements the asset management system of the present invention and is connected to a network 2 such as the Internet. In the server apparatus 1, a CPU 11 that performs various calculations and controls each unit centrally and a RAM 12 that is a work area of the CPU 11 are connected via a bus 13. A magnetic storage device 14 that stores various programs and fixed data and a communication control device 15 that communicates with the outside via the network 2 are connected to the bus 13 via a predetermined interface.

  Asset management data 21 is stored in the magnetic storage device 14 of the server device 1. The asset management data 21 can be read by a predetermined reading device and stored in the magnetic storage device 14 as stored in a storage medium such as an optical disk. A viewer program for browsing the asset management data 21 is set up in the client device 3 that can communicate with the server device 1 via the network 2. Thereby, by accessing the server apparatus 1 from the client apparatus 3, the asset management data 21 can be browsed and operated on the client apparatus 3.

  Next, details of the asset management data 21 will be described. First, creation of the asset management data 21 will be described. The asset management data 21 is created based on the asset management data creation program by a computer different from the server device 1, for example. Thereby, the asset management data 21 is created as follows.

  FIG. 2 is a flowchart of processing for creating the asset management data 21. First, image data of a three-dimensional image prepared by using a three-dimensional CAD (Computer Aided Design) system for a drawing of a building that is a fixed asset to be managed is prepared. Then, with respect to the image data of the three-dimensional image, “model No.” serving as first identification data for identifying each member constituting the building and second identification data for identifying each room of the building "Room No." and "classification data" indicating the classification of each member constituting the building are added (Y in step S1). The classification of each member indicated by the classification data includes types such as “major classification”, “medium classification”, “small classification”, and “fine classification”. Such processing is the first step.

  Next, the above-mentioned “room No.” and “classification data” (“major classification”, “medium classification”, “small” are added to the document data of the estimate of the building, which is a fixed asset to be managed, and the settlement breakdown. "Classification" and "Fine classification") are added (Y in step S2). This processing is the second step.

  Next, the asset management data 21 is generated by combining the image data of the three-dimensional image to which such data has been added and the document data of the estimate and the adjustment breakdown (step S3). This process is the third step.

  In addition, a classification master is prepared for the computer on which the asset management data creation program is set up. The classification master includes the “classification data” (“major classification”, “medium classification”, “small classification”, “fine classification”) of the various parts that make up the building, and the useful life and depreciation method (“fixed rate”). ”Or“ Fixed amount ”) or the like. When the asset management data 21 is created by combining the image data of the three-dimensional image with the document data of the estimate and the settlement statement, the useful life and depreciation in the classification master are obtained from the “classification data” of each member. Data such as a method is read, and these data are associated with each member of the building in the asset management data 21 and added to the asset management data 21 (step S3).

  The asset management data 21 created in this way is configured by combining image data of a 3D image of a building created by 3D CAD, and document data of a building estimate and a settlement breakdown. Each member constituting the building of the three-dimensional image has a model number for identifying each member. And a room No. identifying each room in the building in which each member is arranged. Are associated with classification data indicating the classification of each member. In addition, each room of the estimate of the document data and the breakdown of the account settlement statement has a corresponding room number. And the classification data are associated with each other.

  Next, a method for using the asset management data 21 will be described. The user of the client device 3 accesses the server device 1 and prepares the asset management data 21 to be operable on the client device 3. Such processing is a preparation step. Then, the image data of the asset management data 21 can be displayed on the display of the client device 3 together with the data associated with the image data. Further, the document data of the asset management data 21 can be displayed on the display of the client device 3 together with the data associated with the document data. Such processing is a display process. Details of the display process will be described below.

  A more specific method of using the asset management data 21 will be described. FIG. 3 is an example of a screen display of image data of a three-dimensional image. As shown in FIG. 3, the image data of the three-dimensional image displayed on the screen 31 is set with a viewpoint 32 for displaying the image for each space of the three-dimensional image. The viewpoint 32 is a position in the space of the three-dimensional image that determines the display range of the screen 31 when displaying the three-dimensional image on the screen 31 (details of how to use the viewpoint 32 will be described later). If the direction is determined, the range of the three-dimensional image viewed in the direction is determined from the position of the viewpoint 32, and the three-dimensional image in the range is displayed on the screen 31. For each viewpoint 32 and its orientation, the room No. Is associated. This room No. Is set to the room (room 33 in the example of FIG. 3) in the three-dimensional image displayed on the screen 31 according to the viewpoint 32 and its orientation. In addition, each room No. The room no. The detailed data of the room indicated by is also associated and registered.

  The user of the client device 3 can display a three-dimensional image of the asset management data 21 on the screen of the client device 3. Then, the client device 3 can be operated to move inside or around the building of the three-dimensional image on the screen.

  As shown in FIG. 4, the client apparatus 3 includes a viewpoint No. 32 associated with the viewpoint 32 corresponding to the three-dimensional image currently displayed on the screen 31 and its orientation. Is determined (step S11). Thereby, the viewpoint 32 and its direction are designated. And the room No. The detailed data of the room corresponding to is superimposed and displayed on the three-dimensional image (step S12). Further, when the user makes a request by operating the client device 3 (Y in step S13), in the asset management data 21, the room No. Model no. Information such as the member name of each member, the classification data, the estimate of the document data, and the breakdown of the settlement breakdown are displayed as a list superimposed on the three-dimensional image (step S14).

  As shown in FIG. 5, when the user selects a certain member in the room on the three-dimensional image (Y in step S21), the model number of the member is changed. Information such as the classification data associated with the document, the estimate of the document data, and the breakdown of the settlement breakdown (step S22).

  6 to 10 show examples of screen display in the processing of FIGS. 4 and 5. In FIG. 6, an image 42 of a room is displayed in the screen 41 when the user operates the client device 3. In addition, detailed room data 43 is displayed over the room image 42. In this example, the detailed data 43 includes information such as the room ID, level (which floor of the building), height, and room name.

  FIG. 7 shows the display of the detailed data 43 of the room overlaid on the room image 42 by the user operating the client device 3, and the member names, classification data, and document data of each member in the room. A list 44 in which information such as each breakdown of the estimate and the settlement breakdown is listed and displayed.

  FIG. 8 is an example in which the list 44 is enlarged and displayed. The title displays the room name 51 of the corresponding room, the acquisition price 52 (known from the estimate and the settlement statement), and the opening book value 53 (known from the estimate and the settlement statement).

  In the list, information on each member constituting the room is displayed as a list. Here, the asset name 54, major classification 55, middle classification 56, minor classification 57, opening book value 58 (found from the estimate and settlement breakdown), acquisition price 59 (known from the estimate and settlement breakdown) Etc. are listed for each member.

  9 and 10 show examples of image display of information displayed in step S22. In this example, a sprinkler head that is a member of a room is selected and the information is displayed. FIG. 9 is a display example of detailed information of the asset of the sprinkler head, and FIG. 10 is a display example of detailed information of the accounting of the sprinkler head. These images can be switched on the screen.

  In the above example, the detailed information is displayed from the three-dimensional image of the building. Next, an example of displaying the three-dimensional image of the building from the detailed information will be described.

  First, in the image data of a three-dimensional image of a building of the asset management data 21, each member constituting each room has coordinate data in the three-dimensional image. Further, the above-described viewpoint 32 is set by default in each room.

  As shown in FIG. 11, first, the user operates the client apparatus 3 to select one item item from the list 44 shown in FIGS. 7 and 8 (Y in step S31). Then, the model number associated with the member is changed. And Room No. Are extracted (step S32). Next, the extracted room No. Based on the viewpoint 32 associated with the default by the room No. Are displayed (step S33). And the room No. The corresponding model No. in the room of The direction of the image is moved so that the member No. is displayed on the screen (step S34). This member is displayed so as to be easily noticeable, for example, by blinking (step S35). The corresponding model No. A technique for displaying these members in the screen will be described later.

  FIG. 12 shows a display example of the selected member. A room 63 in which the member 61 is provided is displayed on the screen 62 so that the selected member 61 enters the screen 62. Further, in this example, the member 61 is blinked so that the member 61 is conspicuous.

  As described above, according to the asset management data 21, it is possible to easily display detailed information from a three-dimensional image of a building, and conversely, display a three-dimensional image of a building from detailed information. In building management, the contents of assets can be easily confirmed for each room.

  When such asset management data 21 is used, assets can be easily grasped even when the target building is repaired. First, when repairing a building, as shown in FIG. 13, a member to be removed is selected from the list 44 shown in FIGS. 7 and 8 (step S41). When this selection is finished (Y in step S41), the asset name 54, major classification 55, middle classification 56, minor classification 57, opening book value 58, acquisition price 59, etc. of each selected member are listed (see FIG. 8). It is displayed (step S42). If a desired member is selected from this list, detailed information of each member as shown in FIGS. 9 and 10 can be displayed.

  Thereby, it is possible to easily confirm in advance how much the cost of the member to be removed will be, so that it is possible to perform repair by checking this cost in advance.

  Further, the asset management data 21 can be corrected assuming the state of the building after repair. In this case, a process according to FIG. 2 is performed based on the asset management data creation program. That is, in step S1, the model number of the member to be removed by repair is set. And Room No. And the classification data (in fact, even if the deletion operation is performed, the data remains without being deleted, and information indicating that the data is before repair is added). Is a new model no. And Room No. And the classification data (information indicating that the data has been repaired is added to the newly added data).

  Next, in step S2, in the document data of the estimate of the building, which is a fixed asset to be managed, and the document data of the adjustment breakdown, the room No. And the classification data (in fact, even if the deletion operation is performed, the data remains without being deleted, and information indicating that the data is before repair is added). Is a new room no. And the classification data (information indicating that the data has been repaired is added to the newly added data).

  Then, new asset management data 21 is created by combining the image data of the three-dimensional image from which such data has been deleted and added, and the document data of the estimate and the adjustment breakdown (step S3). ).

  Thus, by recreating the asset management data 21, it is possible to easily confirm the newly recorded asset.

  Moreover, since the data which deletes before and after repair and the added data are attached with the information which shows that, the data before repair and the data after repair can be switched and displayed easily. In addition, data deleted before and after repair (actually data remains), and added data are accompanied by information to that effect, so that additional assets and assets required for retirement processing are also available. Since the breakdown can be understood, these can be easily grasped. When a three-dimensional image is indicated by data after repair, it is possible to display the removed member superimposed on the three-dimensional image after repair based on the remaining image of the member before repair. In that case, the removed member is displayed in a watermark, for example, so as to clearly indicate the removed member.

  Furthermore, accounting data necessary for accounting processing can be created from the data of the asset to be additionally recorded and the asset to be retired.

  By the way, in step S34 of FIG. Based on the viewpoint 32 associated with the default by the room No. Is displayed, and the room No. is displayed. The corresponding model No. in the room of The orientation of the image is moved so that the member is displayed on the screen. In this way, the member in the three-dimensional image is selected and the room No. A means for determining the screen size in the optimum viewpoint direction based on the coordinates of the selected member when the screen moves according to the above will be described.

  In FIG. 14, a screen 71 is a screen on which the user is browsing the asset management data 21 on the display of the client device 3. The size of the screen 71 is “a: b” in the vertical and horizontal directions, and “a: b = n: m” when the aspect ratio is n: m.

Viewpoint _{V G} represents the aforementioned point of view 32. The center of gravity G is the center of gravity of the screen 71, which is the center of the screen 71 in this example. Distance h is the distance between the viewpoint V _G and the center of gravity G. The viewing angle θW is a lateral viewing angle, for example, 60 °. The viewing angle θI is a vertical viewing angle, for example, 75 °. These viewing angles can be set as desired by the user.

  In the asset management data 21, the screen size can be determined as follows according to the user's desire.

First, when giving priority to the viewing angle θW in the horizontal direction,
b = 2h × (tan (θW / 2)) ⁻¹
The horizontal size b of the screen 71 is first determined by
a = 2b × (tan (θW / 2)) ⁻¹ × (n / m) by a = b × (n / m)
To determine the vertical size a of the screen 71.

Next, when giving priority to the viewing angle θI in the vertical direction,
a = 2h × (tan (θI / 2)) ⁻¹
The vertical size a of the screen 71 is first determined by
b = 2h × (tan (θI / 2)) ⁻¹ × (n / m) by b = a × (n / m)
To determine the horizontal size b of the screen 71.

  Next, determination of the viewing direction of the screen 71 will be described. First, the case where there is one member to be displayed in the screen 71 will be described.

In FIG. 15, the initial value viewpoint coordinate V _GO is the barycentric position of the room 72. This initial value viewpoint coordinate V _GO indicates a viewpoint set by default in each room described above. The center of gravity M _G of the target member indicates the center of gravity of the member 71 to be displayed on the screen 71.

First, _(having a direction of _{V GO} from _{M G,} the length vector of _V GO _{M G)} normal vector _{(V GO} M G) to set the plane passing through the center of gravity _{M G} against. Next, a screen 71 having a screen size a: b with the center of gravity M _G as the center of gravity (center) is set based on the above-described determination of the screen size with the distance h between V _GO M _G.

  Next, determination of the viewing direction of the display on the screen 71 when there are two members to be displayed on the screen 71 will be described.

In FIG. 16, the same reference numerals as those in FIG. 15 are the same as those in FIG. There are two target members, and the centers of gravity are M _G1 and M _G2 , respectively. Here, _{M G} is the midpoint of the center of gravity _{M G1} and _{M G2.} Setting a plane passing through the middle point _{M G} with respect to the normal vector _(V GO _{M G).} Then, V _GO M _G is set as the distance h, and the screen 71 having the screen size a: b with the center of gravity _MG as the center of gravity (center) is set based on the determination of the screen size described above.

In this case, if the center of gravity M _G1 and M _G2 are not included in the set screen size, the position of the viewpoint V _{GO is} moved so as to move away from the midpoint M _G on the normal vector (V _GO M _G ). (The viewpoint at that time is the viewpoint V _Gn ). When the screen size a: b includes both the centers of gravity M _G1 and M _G2 , the viewpoint V _Gn is determined there. _Then, when the distance h of the _V Gn _{M G} and distance _{h n,} the distance _h again screen size based on _n a: determining b. If the viewpoint V _Gn is out of the space that can be assumed in the three-dimensional image by this operation, a warning is issued to the user and the fact is notified.

  Next, determination of the viewing direction of the display on the screen 71 when there are three or more members to be displayed on the screen 71 will be described.

In FIG. 17, the same reference numerals as those in FIGS. 15 and 16 are the same as those in FIGS. In this example, there are three target members, and the centers of gravity are M _G1 , M _G2 and M _G3 , respectively.

First, two are selected from the center of gravity of all the members, and the included angle is calculated. The maximum included angles are set to M _G1 and M _G2 . _Then, the middle point between M _{G1, M G2} and _{M G.}

Then, set the plane passing through the middle point _{M G} with respect to the normal vector _(V GO _{M G).} Then, V _GO M _G is set as the distance h, and the screen 71 having the screen size a: b with the center of gravity _MG as the center of gravity (center) is set based on the determination of the screen size described above. Then, forward projecting the centroid of the remaining member with respect to the aforementioned plane passing through the middle point M _G.

In this case, if the center of gravity M _G1 and M _G2 are not included in the set screen size, the position of the viewpoint V _{GO is} moved so as to move away from the midpoint M _G on the normal vector (V _GO M _G ). (The viewpoint at that time is the viewpoint V _Gn ). When the screen size a: b includes both the centers of gravity M _G1 and M _G2 , the viewpoint V _Gn is determined there. _Then, when the distance h of the _V Gn _{M G} and distance _{h n,} the distance _h again screen size based on _n a: determining b. When the viewpoint V _Gn goes out of the space that can be assumed in the three-dimensional image, a warning is issued to the user and the fact is notified.
