Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor plan information distribution format for displaying a high quality three-dimensional floor plan when posting home information on a homepage of the Internet, and the like. It is about services.

[0002]

[Prior Art] On homepages of the Internet,
Conventionally, when posting housing property information, the floor plan is posted as image data along with the location conditions and price of the house, and the user simply searches and views that information using the Internet browsing software. Met.

If the floor plan is created as three-dimensional floor plan data and distributed on the Internet or the like, the floor plan can be displayed as a three-dimensional floor plan on the browsing side.
However, it is necessary to create the 3D floor plan data using 3D model creation software, and even a specialized operator who is familiar with the operation of the software needs a lot of time to create it. .

In the "floor plan / site drawing distribution / posting system" (application number: Japanese Patent Application No. 2000-36847), the point is improved so that the floor plan and site drawing are not image data but the type, size and position of the room. It can be distributed as numerical information such as, and can be reconstructed and displayed in a two-dimensional floor plan on the floor viewing side, or can be displayed as a three-dimensional floor plan by giving height information. However, in displaying a three-dimensional floor plan, real-time rendering (real-time drawing) using software or hardware functions is performed, so that light source positions, viewpoint positions, walls, and walls defined in the three-dimensional space are displayed. The image quality was only such that it was displayed with shading calculated from information such as the normal direction of the surface that is a component of the floor and the like.

From the three-dimensional floor plan data, the ray tracing method (tracking the trajectory of light, refraction and transmission through glass, reflection by a mirror, shadows caused by light being blocked by an object, etc. are calculated. Method) or radiosity method (a method of calculating the equilibrium calculation of light energy to obtain a soft shadow due to penumbra or reflected light) (hereinafter, these calculations are referred to as "rendering calculations"). It is also possible to create a quality image. However, when generating 3D floor plan data on the floor plan browsing side, it is necessary to install dedicated rendering software on the floor plan browsing side in order to perform rendering calculations, and the burden on the floor plan browsing side (software download) Because of this, the time and money burden for this, the burden of reducing the hard disk capacity due to the introduction of software, etc.) were large and tended to be shunned.

Although it is possible to compress and distribute the result of the rendering calculation together with the three-dimensional shape data, the floor plan viewing side arranges furniture in the floor plan and examines the layout, walls and the like. When changing the color and pattern of the curtain to study interior coordination,
When part of the floor plan is changed, rendering calculation needs to be performed again, but if the layout viewing side does not have rendering software, recalculation is impossible.

[0007]

In order to solve the above-mentioned problems, the present invention further develops a “floor plan / site plan distribution / posting system” (application number: Japanese Patent Application No. 2000-36847) to provide a floor plan data providing side. The challenge was to realize a system that can efficiently generate 3D floor plan data with 3D and efficiently distribute and display high quality 3D floor plan information (rendering calculation results) by the radiosity method. .

[0008]

In order to solve the above problems, according to the present invention, a rendering calculation for displaying the floor plan three-dimensional shape data, the floor plan data which is the source of the floor plan data, and the high quality three-dimensional floor plan drawing information. Focusing on the result, the configuration shown in FIG.

These databases are distributed in advance to the floor plan browsing side, but the database on the floor plan data providing side may be shared by the floor plan browsing side via the Internet or the like.

The floor plan data inputting / editing means 10 is a means for inputting / editing floor plan information using a mouse or the like, and has a function of defining the size, shape and position of a room by combining figures such as rectangles and polygons. It also has the function of arranging symbols such as joinery and furniture.
At this time, the usage type of the room (living room, kitchen, entrance, etc.) is selected from the room type codes defined in the room type DB 1 and set. When the fittings and furniture are selected from the fittings / furniture parts DB 4 and the position in the room to be placed is designated, the two-dimensional symbol corresponding to the fittings / furniture parts is read from the symbol DB 2 and displayed. Further, material information such as the color and pattern of the floor, walls, and ceiling of the room is selected from the texture DB 3 and set. Further, a light source type is selected from the light source DB 5 for displaying a three-dimensional solid floor plan and for rendering calculation, and arranged on the floor plan.

The floor plan information defined by the floor plan data input / editing means 10 is stored in a file as the floor plan data 20.

FIG. 2 shows an example of the format of the created floor plan data 20. Number of rooms, type code indicating the type of each room, size and position of each room, texture information indicating materials such as wall and floor of room, number of fittings / furniture placed, fittings /
Information such as a symbol code of furniture, a part name, a fitting / furniture arrangement position, the number of light sources, a light source type, a light source position, a direction of a light source, a color and brightness of a light source, and the like are stored.
The information on fittings / furniture and light sources may be in a format that is associated with the room in which they are placed. Also, information such as pillars and beams and attributes such as house prices and addresses. The number of items may be increased or decreased as necessary, such as adding information.

The floor plan three-dimensionalization means 11 uses the floor plan data 2
This is a function to read 0 and make the floor plan three-dimensional.
Information such as the size and position of the room, the type and location of furniture / furniture, etc. is read and converted into 3D floor plan shape data based on the attribute information for three-dimensionalization such as wall thickness and room height. With function. For the fittings / furniture that is placed, read the 3D floor plan shape data of the fittings / furniture parts from the fittings / furniture parts DB4, and if it is a fitting, make a hole according to the fitting shape in the corresponding part of the wall Fit the parts. For the texture set on the wall, floor, or ceiling of the room, the corresponding texture information is read from the texture DB 3 and pasted.

The three-dimensional three-dimensional floor plan shape data 21 is three-dimensional three-dimensional shape data of a floor plan which is three-dimensionally three-dimensionalized by the floor plan three-dimensionalizing means 11.

The rendering means 12 has a function of performing rendering calculation based on the three-dimensional solid floor plan shape data 21. The rendering calculation result is stored in a file as the rendering calculation result 22.

The rendering calculation result 22 is the result of rendering calculation based on the three-dimensional shape of the floor plan data 20, and, for example, when the radiosity method is used as a rendering calculation method, a wall or floor, Luminance distribution information on each surface that constitutes the ceiling is stored. This data does not include three-dimensional shape information.

Since the rendering calculation result 22 is always set with the floor plan data 20, it may be a file name that can be easily inferred from the file name of the floor plan data 20, or may be managed in a database together with the floor plan data 20.

The floor plan data / rendering calculation result distribution means 30 is means for distributing the floor plan data and the rendering calculation result to the browsing side. It is distributed to the browsing side via a communication path such as the Internet or a recording medium such as a CD-ROM.

The floor plan data 40 is the floor plan data distributed to the floor plan browsing side via the floor plan data / rendering calculation result distribution means 30.

The two-dimensional plane floor plan display means 51 reads information such as room type, size, and position from the floor plan data 40, and information such as the type and arrangement position of fittings and furniture, and reconstructs the figure. It has a function to display as a two-dimensional floor plan. At that time, if necessary, the symbol D
The two-dimensional symbolic figure of joinery / furniture is read from B62 and used.

The floor plan three-dimensionalizing means 52 uses the floor plan data 4
It is a function to read 0 and make the floor plan three-dimensional,
It has exactly the same function as the floor plan three-dimensionalization means 11 on the floor plan data providing side.

The three-dimensional three-dimensional floor plan shape data 41 is three-dimensional three-dimensional shape data of the floor plan which is three-dimensionally three-dimensionalized by the floor plan three-dimensionalizing means 52.

The three-dimensional floor plan drawing display means 53 reads the three-dimensional floor plan drawing data three-dimensionalized by the floor plan three-dimensionalization means 52, and designates the position of the viewpoint and the direction of the line of sight to display it as a bird's-eye view. have. In that case, real-time rendering (real-time rendering) is performed in which shadows are calculated and calculated from information such as the viewpoint position, line-of-sight direction, light source position, and normal direction of surfaces such as walls and floors. . Information such as the type of light source (illumination) and its light distribution attribute is read from the light source DB 65 as needed. In addition, by continuously changing the viewpoint position and the line-of-sight direction, it is possible to look like walking in a house.

The rendering calculation result 42 is a rendering calculation result acquired by the floor plan browsing side via the floor plan data / rendering calculation result distribution means 30 according to an instruction from the three-dimensional solid floor plan drawing display means 53. Since the floor plan data 20 on the floor plan data providing side and the floor plan data 40 on the floor plan browsing side have the same contents, and the floor plan three-dimensionalization means 11 and the floor plan three-dimensionalization means 52 also have the same function, the three-dimensional space on the floor plan browsing side. The converted three-dimensional floor plan shape data 41 has exactly the same contents as the three-dimensional floor plan shape data 21 on the floor plan data providing side. Therefore,
The rendering calculation result 42 is equivalent to a rendering calculation based on the three-dimensional floor plan shape data 41 using the same function as the rendering means 12.

In the three-dimensional floor plan drawing display means 53,

By using the rendering calculation result 42 instead of the display in the real-time rendering described in the above, it is possible to display a high-quality three-dimensional floor plan.

In the three-dimensional floor plan drawing display means 53,
When referring to the rendering calculation result 42, the rendering calculation result of a portion that is highly likely to be displayed on the screen is preferentially acquired based on the information such as the current viewpoint position and the line-of-sight direction. By delaying the acquisition of the rendering calculation result of the invisible part, it is possible to display a high-quality 3D floor plan with high completion at an earlier stage. In that case, the rendering calculation result 42 is not a single file, but a plurality of files divided into parts, and even if the mechanism is sequentially acquired via the floor plan data / rendering calculation result distribution means 30. good.

On the floor plan browsing side, the floor plan data 40 can be corrected by the floor plan data inputting / editing means 50. The floor plan data input / editing means 50 is
It has a function of reading the floor plan data 40 and editing the type, size, and position of the room, and the type and position of fittings and furniture.

If necessary, instead of acquiring the floor plan data 20 on the floor plan data providing side via the floor plan data / rendering calculation result distribution means 30, the floor plan data inputting / editing means 50 is used. You can also enter new floor plan data on the viewing side.

The floor plan data inputting / editing means 50 may be a program different from the two-dimensional plane floor plan drawing display means 51 or may be incorporated as a part of the function of the two-dimensional plane floor plan drawing display means 51. .

The floor plan corrected or newly created on the floor-viewing side is saved as the floor plan data 40,
If necessary, the three-dimensional floor plan drawing display means 51 or the three-dimensional floor plan drawing display means 53 can display the three-dimensional floor plan drawing display means 51 or the three-dimensional floor plan drawing display means 53.

The floor plan data 40 corrected or newly created on the floor plan browsing side is passed to the floor plan data providing side as the floor plan data 20 via the floor plan data / rendering calculation result distribution means 30, and the floor plan three-dimensionalization means 1 is provided.
After being three-dimensionalized by 1, the rendering calculation is performed by the rendering unit 12, and the rendering calculation result 22 is stored.

The floor plan created on the floor plan data providing side is stored because the rendering calculation result corresponding to the floor plan data is stored on the floor plan data providing side even if the floor plan is modified or newly created on the floor reading side. Similar to the data, the 3D floor plan display means 53 can display a high quality 3D floor plan.

In FIG. 1, only one pair of floor plan data 20 and rendering calculation result 22 is shown, but a floor plan data is constructed together with attribute data such as a house price and an address by constructing a database. 20 and the rendering calculation result 22 may be managed and given an arbitrary condition so that they can be searched.

When the floor plan browsing side does not edit the floor plan, arrange furniture, change the color or pattern of walls or curtains, the floor plan data need not be editable, and recalculation of rendering is required. There is no. Therefore, on the floor plan browsing side, the floor plan data 2 on the floor plan data providing side is passed through the floor plan data / rendering calculation result distribution means 30.
Instead of 0, the three-dimensional solid floor plan shape data 21 may be directly acquired. FIG. 3 shows the configuration at that time.

FIG. 5 shows an example of the floor plan data creation work on the floor plan data creation side. The floor plan data can be created by using a method such as inputting the room shape with a rectangle or a polygon as shown in FIG. Door fittings such as windows and windows, furniture such as desks and chairs are also shown in Fig. 5 (a).
It can be arranged by specifying the joiner / furniture symbol and the position.

The created floor plan data is stored as a file, and attribute information such as the price or rent of the house, the address, the nearest station name, etc. is given and stored in the floor plan DB 75.

The contents of the floor plan DB 75 on the floor plan data creation side are transferred to the floor plan DB 76 installed on the floor plan data distribution side via a network or a storage medium.

The floor plan data stored in the floor plan DB 76 is processed by the floor plan three-dimensionalizing means in the rendering server 79.
The data is converted into a three-dimensional shape, the rendering calculation is performed by the rendering unit, and the result is stored in the rendering calculation result DB 77. Rendering calculation finished 3
The three-dimensional shape is deleted.

The floor plan browsing side is connected to the Internet 80, and the conditions (price, rent range, area, etc.) of the desired home are set on the home page of the floor plan data providing side, and a search is performed.

On the floor plan distribution side, the floor plan is selected from the floor plan DB 76 based on the given search conditions, and W
It will be delivered to the floor plan viewing side as an EB page. FIG. 6 is an example of a WEB page displayed on the floor plan browsing side. Two
The dimensional plane floor plan is displayed on the screen by the two-dimensional plane floor plan display means on the floor plan viewing side based on the floor plan data acquired from the WEB server 8. Alternatively, the WEB server 78 may be delivered after converting the floor plan data into two-dimensional image data.

On the floor plan browsing side, one is selected from the list-displayed candidates, and an instruction for displaying a three-dimensional floor plan is given. In the example of FIG. 6, a 3D floor plan display is instructed by pressing the [3D display] button.

When the instruction for displaying the three-dimensional floor plan is given, the floor plan data in the computer 82 is used to convert the floor plan data obtained from the WEB server 78 into a three-dimensional floor plan. It is displayed on the screen by the graphic display means.

Viewpoint icon 9 on the two-dimensional floor plan
There is 0, which indicates the position of the viewpoint and the direction of the line of sight. On the three-dimensional solid floor plan, the state when the line-of-sight direction is viewed from this viewpoint position is displayed. FIG. 7 is an example of the display.

Immediately after the floor plan data is three-dimensionally three-dimensionalized by the floor plan three-dimensionalization means, display is performed by using the three-dimensional shape data and the texture information of each room included in the floor plan data and the light source information. FIG. 8A is an example of the display.

In the three-dimensional solid floor plan display means, there is a high possibility of being displayed on the three-dimensional floor plan based on the viewpoint position and the line-of-sight direction (the room where the viewpoint exists,
The priority is set from the wall in the line-of-sight direction, and the rendering calculation result is acquired from the rendering calculation result DB 77 connected to the WEB server 78 in order from the portion with the highest priority.

The obtained rendering calculation result is sequentially reflected in the corresponding portion on the three-dimensional floor plan, and the image gradually becomes higher in quality. FIG. 8 is an example of such a state, and changes like (A), (B), and (C) over time.

The viewpoint icon on the two-dimensional floor plan is
You can change the position or orientation using a mouse. When the position or orientation is changed, the display on the 3D floor plan changes accordingly. Figure 9 (a),
(A) and (C) are examples of changes in the display of the 3D floor plan when the position and direction of the viewpoint icon are changed.

By continuously changing the viewpoint position and the line-of-sight direction in the three-dimensional floor plan, it is possible to display the image as if walking around the house.

The contents of the furniture parts DB on the floor-viewing side can be displayed in a list, and one or more pieces of furniture can be arranged in the floor plan. Figure 10 (A)
(A) is a figure showing an example of an operation of arranging furniture on a two-dimensional floor plan. The desired furniture is selected from the list display classified by the type of furniture and the arrangement position is specified on the two-dimensional floor plan.

The furniture parts DB may be on the homepage of a third party or the like as long as the same item can be referred to by both the floor-viewing side and the floor-plan data distribution side, and CD-
It may be distributed in a medium such as a ROM.

On the floor plan browsing side, when furniture is arranged on the two-dimensional floor plan, the three-dimensional shape of the furniture is read from the furniture parts DB and reflected on the three-dimensional floor plan. FIG. 11A shows a state before the furniture is arranged, and FIG.
Is a display example after furniture is arranged on the three-dimensional floor plan. At this time, the furniture should have a shadow on the floor, but this is not reflected, and the furniture itself is not shaded by the surrounding light sources.

When the furniture is arranged on the floor-viewing side, information uniquely indicating the arranged furniture (ID number, file name, etc.)
Then, information such as the arranged position and the direction of arrangement is transmitted to the WEB server 78 on the floor plan data distribution side via the Internet 80.

The WEB server 78 holds the same floor plan data distributed to the floor plan browsing side, adds the layout information of the furniture received from the floor plan browsing side, and sends it to the rendering server 79.

In the rendering server 79, the floor plan three-dimensionalizing means again converts the three-dimensional shape into the three-dimensional shape, and the three-dimensional shape of the furniture is read from the furniture parts DB. Subsequently, rendering calculation is performed by the rendering means, and the result is temporarily stored in the rendering calculation result DB 77. At this time, it is not necessary to perform rendering calculation for a room that is not affected by furniture arrangement. In other words, you only have to calculate the part where the rendering calculation result changes depending on the furniture arrangement,
The result is stored as difference information.

On the floor-viewing side, the rendering server 7
After the rendering calculation in 9 is completed, the rendering calculation result difference in the rendering calculation result DB 77 is acquired via the WEB server 78.

The three-dimensional stereoscopic floor plan display means on the floor-viewing side reads this rendering calculation result difference and reflects the result on the target furniture and the affected floor. FIG. 11C is an example of the display after the results are reflected.

[0065]

[Effects of the Invention] When creating 3D floor plan data, the same level of operation as creating a floor plan on a 2D plane can be used without using difficult 3D model creation software. Floor plan data is created as numerical information, and by automatically converting it into a three-dimensional structure,
It is possible to efficiently generate 3D floor plan data in a short time. In the case of an apartment of about 3LDK, it took about 20 hours to use the three-dimensional model creating software, but the method of the present invention can create it in about 1 hour.

Both the floor plan distribution side and the floor plan browsing side have the same floor plan three-dimensionalization function, so that three-dimensional solid shape data can be shared. Therefore, the result of rendering calculation on the floor plan distribution side corresponds to the three-dimensional shape data three-dimensionalized on the floor plan viewing side. Therefore, if only the rendering calculation result is received from the floor plan distributing side, the floor plan viewing side will obtain high results. It is possible to display a quality 3D floor plan.

When furniture or the like is placed in the floor plan, the layout calculation can be performed on the floor plan distribution side by passing only the placement information. Further, since it is possible to discriminate where it is placed, it is only necessary to recalculate the necessary rooms, and it is possible to reduce the time required for the calculation and the communication cost for passing the calculation result.
