DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and apparatus for creating and displaying a perspective for a building for automatically creating a perspective such as a bird's-eye view of a building when selling or planning a building such as a house. More particularly, the present invention relates to a method and an apparatus for creating and displaying a perspective for a building, wherein the perspective can be easily and quickly created by a sales representative or the like.

[0002]

2. Description of the Related Art FIG. 14 shows an example of a business cycle when planning and planning a conventional house design.

According to FIG. 14, first, a sales person in charge of a house design visits a client's house for which the house design has been requested, and makes a meeting with the client to determine the position and size of rooms, toilets, baths, and the like. Create a floor plan to be determined (Cycle C
1). Then, the sales representative takes the created floor plan back to the design company and passes it to the design representative. The designer in charge of the design should make a formal floor plan based on the floor plan, and then prepare materials (presentation board) for explaining to the owner in the above floor plans and catalogs. Cut and pasted to create (cycle C2).

[0004] Then, the designer in charge orders a perspective (a drawing made by a perspective method such as a bird's-eye view, an inside view, and an external view) based on the created floor plan (cycle C3). Then, a few days after the visit, the parsing is completed and when the preparation is completed (cycle C
4) Sales and design staff visit the owner's house again,
He had a detailed meeting with the owner again using Perth and a presentation board to plan the house design.

[0005]

As described above, in the conventional business cycle of house design and planning, at the first visit, the sales representative has made a meeting with the owner and made only the floor plan.

However, the created floor plan gives only two-dimensional two-dimensional information, and the owner first confirms what three-dimensional image the floor plan actually has. It was through a perspective such as a bird's-eye view and an introspection map created several days after the meeting. Therefore, the bird's-eye view that was drawn when the owner created the floor plan,
In many cases, there is a difference between the introspection image and the actually created bird's-eye view and introspection map, and it is necessary to recreate it from the floor plan each time (repeated from cycle C1 in FIG. 14 described above). It was troublesome and the operating efficiency was poor. In addition, since it takes several days from creating a floor plan to creating a perspective and presentation board and visiting the owner's house again, the entire business cycle is lengthened,
There was a risk that business competitiveness would decline.

[0007] In addition, a large number of personnel such as a sales person and a design person are required to create a floor plan and to create a perspective and a presentation board from the floor plan, resulting in an increase in personnel costs. Further, since the presentation board is created by cutting and pasting the created perspectives, catalogs, and the like, it takes a lot of trouble and is one factor that increases labor costs.

The present invention has been made in view of the above circumstances, and enables a salesperson to basically create a floor plan, a perspective, and a presentation board by himself, thereby improving business efficiency and sales.

Dashed line).

Next, the overall operation of the building perspective display device 1 according to this embodiment will be described.

When planning and planning a house design using the building creation display device 1, the sales person in charge of the house design
Bring a personal computer 2 to visit the owner's house where the house design was requested and make a meeting with the owner. Then, by operating the mouse or the like of the input device (A) 13, a floor plan for each floor of the house to be created (for example, a floor plan for the first floor) is input on the display (A) 12. CPU (A) 10
Reads the input floor plan (data) and stores it in the storage device (A) 11 (FIG. 4; see steps S1 and FIG. 5).

Subsequently, the salesperson enters the input device (A) 13
To display library part list display command to CPU
(A) Send to 10. The CPU (A) 10 reads out the CG data (for hardware) of all the parts constituting the library parts stored in the storage device (A) 11 based on the transmitted command, and reads the CG data of the display (A) 12, for example. It is displayed overlapping (overlapping) on a part (step S2). As a result, as shown partially enlarged in FIG. 6, the display screen of the display (A) 12 displays the CG of each part (window 1, window 2, table 1, table 2, etc.) constituting the library part. The image is displayed.

Subsequently, the salesperson (or the owner) operates the mouse or the like of the input device (A) 13 while looking at the floor plan and each part displayed on the display (A) 12 and operates the housing. , A part having the desired shape, color, texture, etc. is designated, and the arrangement position of the part on the floor plan is sequentially input. The CPU (A) 10 reads the input part designation data and part arrangement position data and stores them in the storage device (A) 11 (step S3), and also sets whether the height of the parse to be created is specially set. It is determined whether or not (step S4).

If the client wants to specify the height of the perspective, the sales representative inputs the height data into the input device (A) 1.
3 through the keyboard (the process of step S4 →
YES), the CPU (A) 10 reads the height data (step S5), and proceeds to the process of step S6. When the height data is not input from the sales representative (the processing of step S4 → NO), the processing of the CPU (A) 10 directly proceeds to the processing of step S6).

Then, the CPU (A) 10 performs a modeling process based on the perspective creation algorithm and the floor plan stored in the storage device (A) 11 to preliminarily correspond to the floor plan of the house. A three-dimensional model (including at least one of the roof, wall, and floor of the house) from the determined viewpoint position is created and stored in the storage device (A) 11 (step S6). Next, the CPU (A) 10
In the created three-dimensional model, the input (read) CG data (for hardware) of each part is sequentially read out with reference to the library part of the storage device (A) 11, and the CG data is read at the input arrangement position. The three-dimensional models with parts are created by combining them, and are stored in the storage device (A) 11 (step S7).

Subsequently, the CPU (A) 10 performs a hardware rendering process based on a graphic function on the basis of the algorithm for creating a parse and the created three-dimensional model with parts to execute a parse from a predetermined viewpoint position (for example, A color perspective such as a bird's-eye view) is created and displayed on the display (A) 13 (step S8), and the process is terminated (the created perspective data is stored in the storage device (A) 11).
Is memorized). As a result, a perspective (bird's eye view) corresponding to the input floor plan is displayed on the display screen of the display (A) 13 as shown in FIG.

That is, according to this configuration, the sales representative inputs a floor plan on the display (A) 13 and specifies and inputs parts to be arranged indoors and outdoors and the arrangement positions on the floor plan. With very simple operation (Step S
1. Step S3), input floor plan and parts
A perspective view (such as a bird's eye view) that is dimensionally displayed can be automatically displayed on the display (A) 13. Therefore, by looking at the displayed perspective, the owner can check on the spot what kind of three-dimensional image the floor plan actually has, so the very dense planning at the first visit Can be performed. Further, even if the image is different from the image drawn by the user, the process after step S1 may be repeated again on the spot (by modifying or changing the floor plan on the display screen of the display (A) 12). Good), and it is not necessary to recreate the actual perspective as a drawing at all, so that the operating efficiency can be greatly improved.

Also, in the present configuration, parts such as fixtures and fixtures to be placed inside and outside the house can be selected on the display screen of the display and added to the perspective, so that a real image very close to the image of the actual living state can be obtained. Can be displayed.

Further, as shown in FIG.
The perspective position of the perspective (bird's eye view) shown on the screen 2 can be changed. For example, if the owner wants to see a three-dimensional image when a desired position inside each room is set as a viewpoint, the salesperson operates the mouse or the like of the input device (A) 13 to specify and input a desired viewpoint position. I do. CPU (A) 1
0 reads the designated and input viewpoint position data (FIG. 8; step S10). Subsequently, the CPU (A) 10 remodels the three-dimensional model with parts into a three-dimensional model with parts based on the input viewpoint position (step S11).

Then, the CPU (A) 10 performs a hardware rendering process based on a graphic function based on the created three-dimensional model with parts to create a perspective (bird's eye view) from the input viewpoint position, The information is displayed on the display (A) 13 (step S12), and the process ends. As a result, a new perspective (bird's eye view) corresponding to the input viewpoint position is displayed on the display screen of the display (A) 13.

Therefore, the client can visually recognize the perspective from that viewpoint by designating the desired position in the room as the viewpoint position. For example, the owner can continuously move the viewpoint position from the entrance to each room. By doing so, it is possible to simulate and display a three-dimensional stereoscopic image of the house while actually walking in the house.

Note that if you bring a printer for a portable personal computer, you can print a Perth on the spot (at the owner's house).

On the other hand, when the meeting with the owner is completed in this way, the storage device (A) of the personal computer 2
Reference numeral 11 denotes house floor plan data, part data arranged in the house, arrangement position data of the parts, three-dimensional modeling data corresponding to the floor plan data, floor plan data, part data, and arrangement. 3D modeling data with parts and perspective data corresponding to the position data are stored.

After the meeting, the sales representative brings the personal computer 2 back to the company and receives design advice and the like from the designer in charge as necessary. Then, for example, when the client wants to see a higher-quality perspective (a bird's-eye view, an introspective view, an external view, etc.), the sales representative can obtain a high-quality perspective based on the three-dimensional modeling data created by the personal computer 2. Can be created in-house.

That is, after connecting the personal computer 2 to the bus B in the company, the sales representative activates the arithmetic processing unit 3.

Subsequently, the salesperson enters the input device (B) 18
To input a high-quality CG creation command. The CPU (B) 15 of the arithmetic processing device 3 reads the sent high-quality CG creation command (FIG. 9; step S15).

Subsequently, the CPU (B) 15 stores the data in the storage device (A) 11 (input in step S3).
The CG data of the software part corresponding to each part data is sequentially read out with reference to the library part of the storage device (A) 11, and is combined with the disposition position stored in the storage device (A) 11. A three-dimensional model with parts is created (step S16).

Next, the CPU (B) 15 stores the storage device (B) 1 based on the created three-dimensional model with parts.
6, a software rendering process (CG process) including texture mapping is performed in real time based on the algorithm for high-quality CG processing stored in 6 to create a high-quality CG perspective (for example, a bird's-eye view) from a predetermined viewpoint position. Is displayed on the display (B) 17 (step S17), and the process is terminated (the created high-quality CG parse data is stored in the storage device (B) 16). As a result, on the display screen of the display (B) 17, a perspective corresponding to the input floor plan is displayed with more excellent image quality in detail clearly and realistically.

As described above, according to this configuration, since the three-dimensional model based on the floor plan is created in advance at the time of the meeting, the sales representative immediately returns to the processing unit 3 after returning to the company. Is activated to perform the software rendering process, thereby making it possible to create a high-quality CG perspective during the day of visiting the owner's house. Note that the high-quality CG perspective displayed on the display (B) 17 can be output by the printer 5.

Further, the sales person in charge of the house prepares a plan view, an elevation view,
And detailed design drawings such as sectional views can be created in-house.

That is, the sales person first operates the input device (C) 23 to send a perspective display command (FIG. 10;
Step S20). The CPU (C) 20 reads the perspective data stored in the storage device (A) 11 in response to the transmitted perspective display command, and displays it on the display (C) 22 (step S21). As a result, the perspective shown in FIG. 7 is displayed on the display (C) 22.

Then, the salesperson displays (C)
On the perspective displayed at 22, a desired vertical sectional position is designated. The CPU (C) 20 reads the designated section position data (step S22).

Subsequently, the CPU (C) 20 creates the three-dimensional model with parts stored in the storage device (A) 11, the input cross-sectional position data, and the detailed design drawing stored in the storage device (C) 21. Based on the algorithm for use, a detailed plan view, detailed elevation view, and detailed cross-sectional view at the specified cross-sectional position where dimensions corresponding to the three-dimensional model with parts are written are created (step S23).

Then, the CPU (C) 20 displays the created detailed plan view, detailed elevation view, and detailed sectional view on the display (C) 22 (step S24), and ends the processing.

As described above, according to the present configuration, since the three-dimensional model based on the floor plan is created in advance at the time of the meeting, the sales representative immediately returns to the company after returning to the company. Is activated and the detailed design drawing creation process is performed, so that detailed design drawings such as a detailed plan view, a detailed elevation view, and a detailed sectional view can be created during the visit day of the owner's house. The detailed plan view, detailed elevation view, and detailed sectional view displayed on the display (C) 22 can be printed out by the printer 5.

In the detailed design drawing, it is not necessary to prepare all of the detailed plan view, detailed elevation view, and detailed sectional view described above, and at least one of them may be prepared. If a cross-sectional view is not created, the processing of steps S20 to S22 need not be performed.

Furthermore, the salesperson must at least select one of the house parts created by the personal computer 2, the high-quality CG perspective created by the arithmetic processing unit 3, and the detailed design drawing created by the arithmetic processing unit 4. In the embodiment, the layout and editing of the house parts and the detailed design drawing created by the personal computer 2) can be automatically performed to create a PB in which the perspective and the detailed design drawing are described.

That is, the sales representative first operates the input device (C) 23 to send a PB creation command (FIG. 11; step S30). The CPU (C) 20 responds to the sent PB creation command by sending the PB stored in the storage device (C) 21.
A PB screen is created based on the creation algorithm and displayed on the display (C) 22 (step S31). The CPU (C) 20 sequentially reads out the parse data and the CG data of each part included in the parse data with reference to the storage device (A) 11 and stores a detailed design drawing (for example, a detailed plan view) in the storage device. (C) Read with reference to 21 (step S32).

Subsequently, the sales representative operates the mouse or the like of the input device (C) 23 to display a detailed plan view on the PB screen,
The layout position of the CG image of the perspective and the main parts is designated (step S33). In addition, sales reps
By operating the mouse and keyboard of the input device (C) 23, data (hereinafter, collectively referred to as character data) such as characters, symbols, and illustrations to be described on the PB and a layout position of the character data on the PB are displayed. Specify (Step S
34).

When the input of the character data is completed, the CPU
(C) 20 is based on the PB creation algorithm and the layout position data such as the detailed plan view and the character data stored in the storage device (C) 21,
A layout is automatically edited on the PB screen on the CG image and the character data of the part to create a PB (step S35). Then, the CPU (C) 20 prints out the created PB via the printer 5 (step S36), and ends the process.

As a result, as shown in FIG. 12, a PB in which a detailed plan view, a perspective, a CG image of a main perspective, and character data are mixed can be automatically created.

As described above, according to this configuration,
Create PBs created by cutting and pasting catalogs, etc. with extremely simple work by laying out parts created by the personal computer 2 and detailed design drawings etc. created by the processing unit 4 together with character data. Can be. In the above-mentioned PB, CGs of perspectives and parts are placed on the PB. However, it is also possible to connect an image input device such as a scanner via the bus B, and place an image input from the scanner on the PB. is there.

Here, the total effect of the present embodiment will be considered by comparing business cycles.

FIG. 13 is a diagram showing an example of a business cycle using the building perspective system of this embodiment.

According to FIG. 13, the sales representative first visits the owner's house for which the home design sales representative has requested a home design. At that time, the sales representative makes a meeting with the owner, inputs the floor plan via the display of the personal computer for the form on the spot, and instantly obtains a color perspective (three-dimensional image) corresponding to the input floor plan. (See FIG. 4; steps S1 to S8).
In addition, even when the salesperson does not follow the expected image of the owner, the sales representative only has to input (change) the floor plan again on the display screen of the display, and a specific and detailed meeting can be made with one visit. (Cycle C10).

After the meeting, the sales representative performs the above-described processing shown in FIGS. 9 to 11 while receiving design advice and the like as necessary, thereby outputting high-quality CG within the day. A detailed design drawing can be automatically created and PB can be output. That is, a high-level house design plan can be proposed in a short period of time (cycle C11).

In this way, high quality CG perspective and PB
Etc. are completed and the preparation is completed (Cycle C
12) It is possible to plan the house design by visiting the owner's house again on the first visit day, for example, the next day, and again making detailed meetings with the owner using PB or the like.

When the above business cycle is compared with the conventional business cycle (FIG. 14), the following advantages are obtained.

That is, in the business cycle of this embodiment, from the first visit to the creation and proposal (planning) of a high-quality CG perspective or PB, the process is completed in only one day. Several days before the proposal). Therefore, business competitiveness can be dramatically improved.

At the first visit, a three-dimensional image of the floor plan is provided to the owner in a perspective (color perspective).
Since it is possible to repeatedly create a floor plan having a three-dimensional image that matches the image drawn by the owner, it is possible to create a floor plan with a high degree of perfection as of the visit date. Therefore, it is not necessary to visit the owner's house again due to the modification of the floor plan, etc., so that it is possible to reduce the visit load and improve the business efficiency and the business competitiveness.

Further, as can be seen from the cycle diagram of FIG. 13, in the sales cycle C of the present embodiment, basically, a sales person alone creates a high-quality CG perspective, detailed design drawings, and PB from perspective creation. Therefore, it is possible to drastically reduce personnel and labor costs required for housing planning.

A program in which the above-described algorithm for creating a parse is described is stored in a storage medium such as a CD-ROM, and when the personal computer 2 is used, the storage medium is stored in an external storage device (CD-ROM drive). To load the program. In addition, high quality CG
A program describing an algorithm for processing, a program describing an algorithm for creating a detailed design drawing, and P
The same applies to a program in which an algorithm for creating B is described.

In this embodiment, a house was described as an example of a building. However, the present invention is not limited to this, and any building may be used as long as a floor plan is required. However, it is applicable.

Further, in this embodiment, a bird's-eye view is created as a perspective of a house. However, the present invention is not limited to this.
Also, it is of course possible to create a required number of bird's-eye views, introspection views, external views, and the like.

[0082]

As described above, by using the method and apparatus for creating and displaying a building perspective according to the present invention, the floor plan is automatically input from structural data such as a floor plan at the meeting with the owner. Since a perspective that gives the three-dimensional image of the figure can be easily created and displayed and checked by the owner, the number of days required for the conventional perspective creation and the like can be reduced, and the business cycle can be significantly shortened.

In particular, in the present invention, the 3
Based on the dimensional model, software rendering processing including texture mapping can be performed to create and display high-quality perspectives. Can be displayed.

Therefore, the owner can recognize the three-dimensional image of the floor plan more realistically and in detail by visually recognizing the high-quality perspective corresponding to the floor plan, and can meet the request of the owner. Business efficiency can be further improved.

According to the present invention, since the second computer graphics data for software rendering representing parts is stored in the storage means (memory) in advance, the second computer graphics data is used. By performing the software rendering process during the visit day to the client house, a high-quality perspective including a computer graphics image corresponding to a predetermined part can be created. Therefore, the number of days required to create a high-quality perspective can be reduced, and the business cycle can be significantly reduced.

In the present invention, during the visit to the owner's house,
Since detailed design drawings and presentation boards can be created, the number of days required for conventional detailed design drawings and presentation board creation can be reduced, and the business cycle can be significantly shortened.

That is, since the planning of a house can be performed more quickly than other companies by drastically shortening the business cycle, the business efficiency and business competitiveness can be greatly improved.

In addition, from the above-mentioned perspective creation, high quality CG
Since a person in charge of sales, such as a perspective, a detailed design drawing, and creation of a presentation board, can be basically executed by one salesperson, the number of people involved in house planning can be reduced, and as a result, labor costs can be reduced.
