BACKGROUND OF THE INVENTION
  The present invention creates shape data of a building such as a house by a computer, and based on the shape dataAboveGenerate and display CG images (images by computer graphics) representing the inside and outside of the buildingWhen,AboveCG image can be displayed on the original structure of the building and the structure after the reconstruction.,Display method of building renovation plan by CG image anddisplayEquipment, andThe displayA computer-readable recording of a program for causing a computer to execute the method.OnlyTakeRPossible recording mediaIs a thing.
[0002]
[Prior art]
Conventionally, when building a building such as a house, a three-dimensional shape data of a planned house that has been completely designed is created, and a workstation installed in a presentation room (display room) in a sales office of a construction company is installed. A display method has been proposed in which the house is displayed as a CG image on an appropriate display device such as a screen based on the three-dimensional shape data (see JP-A-9-106408). In that case, the building can be displayed as a moving image on the display device by appropriately moving the viewpoint of the building on which the operator of the building company is displayed.
[0003]
According to this display method, the customer can perform the same experience (so-called walk-through) on the CG image as if he / she actually walked in and out of the house planned for construction on each part of the house planned for construction. Therefore, it is possible to make an appropriate change in the design of the house based on the result of the walk-through. Therefore, compared to the case where the house is constructed only by presenting the design drawing to the customer, when the modification based on the walk-through based on the CG image is performed, the design failure and the usability after the construction of the house are improved. The number of complaints from customers such as badness is greatly reduced, which is beneficial to both the construction company and the customer.
[0004]
[Problems to be solved by the invention]
By the way, in the case of building a house, in general, the floor plan etc. is often determined in consideration of the demand at the beginning of the building or at most several years ahead, but in reality, the house is usually several tens of years or more. Since it has a long life, it is often necessary to renovate it according to the increase or decrease in family members, changes in the age group, or the occurrence of physical injury.
[0005]
Even in this case, if the customer and the remodeling company proceeded with the construction by simply having a meeting on the drawing, the room after renovation would be different from the customer's image or the renovation. There is a risk of problems such as poor usability than previously thought.
[0006]
In addition, if the floor, wall, or ceiling is required to be changed or reinforced at the time of renovation, there is a problem that the renovation work becomes large and the cost is high. Therefore, it is preferable to make a plan for renovation from the beginning of construction, and to determine the initial floor plan after considering that the renovation can be performed with a minimum amount of work as needed in the future. Therefore, the present invention displays a renovated house or the like by a CG image at the time of renovation, or a preferable renovation plan in the case of renovation if necessary in the future as well as the original structure of the house at the time of new construction. It can be displayed.
[0007]

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings. As shown in FIGS. 1 and 2, the display chamber 1 is provided with a rotatable door 2 in the vicinity of the two corner portions thereof, and a blind that can be moved up and down on a wall 3 at the rear portion (lower portion in FIG. 2). While a vertically long window 4 having 4a is formed, a rectangular screen 5 is fitted in the wall 3 at the front (upper part in FIG. 2). The screen 5 is, for example, a large screen having a size of about 100 inches or more (the number of pixels is, for example, about 1280 × 1024 dots or more).
[0011]
In the vicinity of the ceiling of the wall 3 at the rear of the display room 1, for example, a projector 7 (projector) having three projection tubes 6 is installed so that a projected image is projected from the projector 7 toward the screen 5. It has become. Note that a separate projection chamber may be provided on the back side of the screen 5 so as to project from the back side of the screen 5.
[0012]
In the display room 1, a plurality of chairs 8, a table 9, and the like for use by a customer K who appreciates a CG image projected on the screen 5 are arranged. A display device 12 (CRT: Cathode Ray Tube or the like) of a workstation 11 (computer) for creating a CG image relating to a house to be built by the customer K and displaying it on the screen 5, a keyboard 13 and a mouse as input devices 14 is installed.
[0013]
An arithmetic processing unit 16 constituting the main body of the workstation 11 is installed below the auxiliary table 15 disposed near the corner of the display chamber 1, and on the auxiliary table 15 on the screen 5. A color printer 17 for appropriately printing a displayed image and a scanner 18 for capturing the image in the workstation 11 are mounted.
[0014]
As shown in FIG. 3, the arithmetic processing unit 16 has a shape data storage unit 16a for storing the shape data of the building created based on external input from the keyboard 13, the mouse 14, etc., and the shape data storage unit 16a. A CG image data generation unit 16b that generates CG image data for displaying a CG image related to the building by moving a viewpoint V (described later) set with respect to the stored shape data, or the CG image. Based on the CG image data generated by the data generation unit 16b, the display unit includes a display control unit 16c that causes the display unit 12 and the screen 5 to display a CG image related to the building.
[0015]
In addition, the shape data storage unit 16a includes an initial structure storage unit 16d that stores shape data related to the original structure of the building, and a post-reconstruction structure storage unit 16e that stores shape data related to the structure after the reconstruction.
[0016]
And in this arithmetic processing unit 16, the house data for creating the three-dimensional shape data showing the said house by creating the floor plan etc. showing the layout of each floor of a house (building), the arrangement of fixtures, etc. In accordance with the creation program P1, the CG image generation program P2 for rendering each part of the house on the screen 5 or the like as a moving image or a still image on the screen 5 based on the three-dimensional shape data, a standard reconstruction plan, etc. A remodeling support program P3 and the like for easily making changes and the like are installed from an appropriate recording medium such as a CD-ROM. It should be noted that processing such as creation of shape data and generation of a CG image can be performed using a so-called personal computer in addition to the workstation 11.
[0017]
Hereinafter, a procedure for displaying a CG image in the display chamber 1 will be described. As shown in FIG. 4, the operator S of the construction company displays a plan view of each floor of the house H to be built by the customer K on the display device 12 before the customer K visits the display room 1. A tool T (button, selection field, etc.) displayed in the tool display area A2 on the right side is created in the image display area A1 of the screen for creating a plan view.
[0018]
This plan view can be prepared together with a plan view showing a renovation plan in the case of renovation as needed, in addition to the one representing the structure at the beginning of construction. In that case, a plan view of the structure at the beginning of construction is stored in the initial structure storage means 16d in the shape data storage section 16a, and a plan view showing the renovation plan is stored in the post-remodeling structure storage means 16e. The structure at the beginning of construction and the structure after renovation can be selected in the structure selection column C1.
[0019]
First, when creating a floor plan at the beginning of construction, after selecting “initial structure” in the structure selection column C1, the floor plan is created for each floor. Although the procedure for creating the plan view will not be described in detail, “room name” and “area” are designated using the tool T displayed in the tool display area A2, and the image display area A1 is used. The floor plan can be designed simply by designating the position at which the “room” is arranged with the mouse 14 or the like. Furthermore, the equipment can be arranged simply by specifying the “type” of the “equipment” to be arranged in each room and the arrangement position.
[0020]
Since each room and fixtures used for the above design are created in advance as three-dimensional shape data including height dimensions, it is only necessary to create a plan view such as FIG. 4 for each floor of the house. Three-dimensional shape data of fixtures is created, and the three-dimensional shape data is subjected to processing such as coloring as necessary.
[0021]
Next, after building the house, for example, when creating shape data related to the structure in the case of remodeling according to changes in family members, etc., and presenting it together with the original structure, in the structure selection column C1, For example, “reconstruction candidate 1” is selected, and a plan view relating to the structure after remodeling is created. As a plan view after the reconstruction, the plan view of the initial structure is displayed as it is, and it can be created in a form in which necessary modifications are made to the plan view. As an example, FIG. 5 shows a renovation plan in which the “Japanese room” in FIG. 4 is changed to a Western-style “child's room”. A plurality of types of such renovation plans can be prepared based on the wishes of the customer K itself or in the form of a proposal from a construction company.
[0022]
Instead of creating the three-dimensional shape data of the house on the workstation 11, the drawing data (three-dimensional shape data) of the house previously created by a CAD system or the like may be taken into the workstation 11 and used. Good.
[0023]
Hereinafter, a walk-through procedure performed when the customer K visits the display room 1 will be described. First, the principle of displaying the inside and outside of a house as a still image or a moving image based on the shape data represented by the plan view or the like will be briefly described.
[0024]
For example, assuming that the three-dimensional shape data representing a house corresponds to the shape shown by D in FIG. 6 and the viewpoint is V and the gazing point is U, the line-of-sight direction E is determined from the viewpoint V. The direction is toward the viewpoint U.
[0025]
When generating an image when the line-of-sight direction E is viewed from the viewpoint V as a CG image, a quadrangular pyramid F corresponding to a predetermined viewing angle is set with the line-of-sight direction E as the center line in the horizontal direction and the vertical direction, A two-dimensional image obtained by projecting an area included in the quadrangular pyramid F in the three-dimensional shape data D onto the projection plane G (a cross section of the quadrangular pyramid F) is cut out, and an image in the projection plane G (see H in FIG. 6). ) Is displayed as a walk-through CG image Q on the screen 5 in FIG.
[0026]
The calculation for generating the CG image Q based on the viewpoint V and the line-of-sight direction E is executed by the CG image generation program P2. For example, when the viewpoint V is moved forward, the area included in the quadrangular pyramid F in the three-dimensional shape data D is reduced, so that the CG image Q depicts a state closer to the house. Thus, according to the forward or backward movement of the viewpoint V or the change of the viewing direction E, the inside and outside of the house are displayed as a moving image or a still image by the CG image.
[0027]
Hereinafter, a specific walk-through procedure will be described. When the walk-through button B1 is clicked in the tool display area A2 in FIG. 4, the walk-through screen in FIG. 7 is displayed. The created plan view is reduced and displayed in the sub-window A3 of the walk-through screen. Here, the operator S sets the viewpoint V and the gazing point U to be the reference for generating the CG image, and from the viewpoint V, A virtual image when the gazing point U is viewed is displayed as a walk-through initial screen in the image display area A1 as a CG image. Here, a walk-through screen when the viewpoint V and the gazing point U are set in the living room is illustrated.
[0028]
When the walk-through is performed, the operator S uses the buttons B2 to B2 such as “forward”, “backward”, “left rotation”, “right rotation”, “upward rotation”, and “downward rotation” in the tool display area A2. When the above-described movement of the viewpoint V or the change of the line-of-sight direction E is performed by appropriately clicking B7 or the like, the change in the viewpoint V or the line-of-sight direction E on the image display area A1 and the screen 5 accordingly. Thus, the interior of the house is displayed as a moving image or a still image by the CG image Q.
[0029]
Normally, only the image display area A1 and the subwindow A3 are displayed on the screen 5, and the tool display area A2 is not displayed. That is, what is shown in each figure after FIG. 7 is the display content of the display device 12 viewed by the operator S, but the display content of the image display area A1 and each subwindow A3 is displayed at each time point. The apparatus 12 and the screen 5 are common.
[0030]
When the operator S clicks the “forward” or “reverse” buttons B 2, B 3 on the display device 12, the viewpoint V moves forward or backward, and although not shown, the CG image Q is displayed in the image display area A 1 and the screen 12. It will be enlarged or reduced. In FIG. 8, a state in which the viewpoint V is advanced from the state of FIG. 7 is displayed. When the “Rotate left” or “Rotate right” button B4, B5 or the like is clicked, the line-of-sight direction E changes to the left or right, and the CG displayed on the image display area A1 and the screen 5 accordingly. The image changes.
[0031]
  In the above, the case where the walk-through is performed based on the structure at the beginning of the construction has been described. However, by selecting a desired reconstruction candidate, for example, the one shown in FIG. You can also walk through. Sodo itIn that case, by preparing a reconstruction plan as shown in FIG. 5 before the customer K visits the display room 1, the reconstruction plan is created without creating a floor plan for the reconstruction during the walk-through. There is an advantage that a walkthrough based on can be started immediately.
[0032]
Next, during the walk-through in the planned construction house, the customer K's plan view of the planned construction house can be instantly changed based on the standard reconstruction plan, or the walk-through can be performed based on this reconstruction plan. The procedure to be performed will be described. In the above reconstruction support program P3, a standard reconstruction pattern is prepared in advance. If you want to present this standard reconstruction plan during a walk-through etc., return to the plan view of FIG. Select the standard renovation plan in column C2.
[0033]
  One or more standard remodeling patterns can be prepared and listed in the instant remodeling column C2, but here, when a bedridden patient occursInFor nursingofI will explain the renovation plan for “care and bedridden”. In this renovation plan, if any room of the house on the image display area A1, for example, “Japanese-style room” is clicked and set as “care room”, the room becomes “care room” as shown in FIG. A drawing in which the ceiling rail R for the electric transfer (not shown) connecting the “care room”, “toilet” and “bathroom” is provided is automatically created. .
[0034]
Here, the electric transfer means that a bedridden patient is placed on a transfer (not shown) and moved between the “care room”, “toilet” and “bathroom” along the ceiling rail R while being driven by an electric motor. Although it is a device, since the route of the ceiling rail R for the electric transfer is automatically determined by the arithmetic processing device 16, the operator S does not need to input the route of the ceiling rail R by itself, and the operation is simplified. Can be achieved.
[0035]
In order to provide the ceiling rail R, the strength of the ceiling portion needs to be higher than usual. However, reinforcing the ceiling portion after building a house is complicated and expensive. Therefore, considering the possibility of installing an electric transfer in the future, it is preferable to reinforce the ceiling near the part where the ceiling rail of the electric transfer may be installed from the time of building the house. It is preferable to advise the customer K.
[0036]
Next, a procedure for automatically determining the route of the ceiling rail R by the arithmetic processing device 16 will be described. The route of the ceiling rail R connecting the “care room”, “toilet” and “bathroom”
(1) The route must be able to pass through without being blocked by a wall.
(2) A path extending in the vertical or horizontal direction (vertical or horizontal direction in FIG. 9).
Is the basic condition. Furthermore, the route of the ceiling rail R is
(3) Do not pass through rooms other than hallways and halls as much as possible.
(4) The route should be as short as possible
Is an auxiliary condition.
[0037]
FIG. 10 shows a procedure for determining the route of the ceiling rail R by the arithmetic processing unit 16 in accordance with the above conditions. In step L1, first, all routes that can connect the “care room”, “toilet”, and “bathroom” are obtained in accordance with the basic conditions. As shown in FIG. 11, these routes are
▲ 1 ▼ “Care room” → “Bedroom” → “Corridor” → “Toilet” and “Bathroom” routes
▲ 2 ▼ “Care room” → “Hall” → “Corridor” → “Toilet” and “Bathroom” routes
▲ 3 ▼ “Care room” → “Hall” → “Living room” → “Corridor” → “Toilet” and “Bathroom” routes
There are three ways.
[0038]
  Subsequently, in step L2, it is determined whether or not there is a route that passes only through the hallway and the hall. That is, when passing through rooms other than the hallway and hall,GOther family members may be affected by the passage of the camera,GThis is because the lance is preferably moved only through the hallway and the hall as much as possible.
[0039]
In this example, the route {circle around (2)} corresponds to a route that passes only through the corridor and the hall. Therefore, the determination result at step L2 is “yes” and the process proceeds to step L3. Here, the route passes through only the hallway and the hall. The route with the shortest distance is selected. In this case, since the route that passes only through the hallway and the hall is only the route (2), the route (2) is selected, and the route (2) is indicated by a dotted line or the like in the image display area A1 as shown in FIG. Is displayed.
[0040]
On the other hand, unlike this example, if there is no route that passes only the corridor and hall between “care room” and “toilet” and “bathroom” in step L2, the process proceeds to step L6, where “care room” ”,“ Toilet ”, and“ Bathroom ”are selected with the shortest distance among the possible routes, and the route is displayed in the image display area A1. In this way, for the standard renovation plan prepared in advance, the operator S can change the plan view instantly without having to input figures one by one, and then based on the plan view after this remodeling, etc. It is possible to perform a walk-through.
[0041]
