Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to whether or not various storage items such as clothes and tableware can be stored in each storage portion when a building such as a house is displayed by a CG image (image by computer graphics). The present invention relates to a storage planning method capable of judging whether a storage medium is stored and a computer-readable recording medium storing a program for causing a computer to execute the method.

[0002]

2. Description of the Related Art Conventionally, when building buildings such as houses,
Creates three-dimensional shape data corresponding to a house that has been completely designed and is scheduled to be built, and uses a workstation installed in a presentation room (display room) in a sales office of a building company to convert the three-dimensional shape data to the above-mentioned three-dimensional shape data. There has been proposed a display method for displaying the house as a CG image on an appropriate display device such as a screen (see Japanese Patent Application Laid-Open No. 9-106408). In that case, the building can be displayed as a still image or a moving image on the display device by appropriately stopping or moving the viewpoint of the displayed building by the operator of the building company.

According to such a display method, a customer can perform on a CG image the same experience (so-called “walk-through”) that is similar to actually walking around inside and outside a house to be built. It is possible to extremely accurately examine whether the design of each part of the house is appropriate, and to appropriately change the design of the house based on the results of the walk-through.

[0004] Therefore, compared to a case where a house is constructed only by presenting a design drawing to a customer, when a correction based on a walk-through using a CG image is performed,
Claims from customers, such as poor design or poor usability after building a house, are greatly reduced, which is beneficial to both building companies and customers.

[0005]

By the way, when designing a house, a storage section such as a cupboard for storing tableware is usually provided in a form to be built in a house, but recently a storage section for storing clothes and the like is also provided. It is often provided in a built-in format. In such a case, there is a problem that if the capacity of the storage unit is insufficient for the amount of various storage items held by the customer, the storage items cannot be stored after the construction, but actually, the storage items held by the customer K are not sufficient. It is difficult to design the storage part after accurately grasping the amount, and the CG as described above is used.
In the walk-through using images, the amount of the stored items was not considered.

Therefore, according to the present invention, in the case of performing a walk-through using a CG image, for example, a storage plan capable of examining whether or not the volume of the storage section is sufficient for the amount of storage items held by the customer. The aim is to provide a method.

[0007]

In order to solve the above-mentioned problems, a storage planning method according to a first aspect of the present invention creates shape data for each floor of a building including a storage portion and stores the shape data in a shape data storage means. After the storage, the size of the storage section is calculated based on the shape data and stored in the storage section size storage means, while the area occupied by the storage object to be stored in the storage section is calculated and the storage area occupation area. The size of the storage section stored in the storage section size storage section is compared with the occupied area of the storage section stored in the storage section occupation area storage section. . Note that the storage unit size storage means and the storage object occupied area storage means are configured by a computer memory or the like.

According to a second aspect of the present invention, in the method of the first aspect, a standard occupied area per unit quantity is previously stored in the occupied area per unit quantity storage means for each type of the stored item. The calculation of the occupied area of the stored item is performed according to the quantity for each type of the stored item and the standard occupied area per unit quantity.

According to a third aspect of the present invention, a shape data of a building including a storage portion is created and stored in shape data storage means, and a viewpoint set for the shape data is displayed by moving or stopping. When displaying a CG image representing the inside and outside of the building on the means, the shape data of the building including the storage section is created and stored in the shape data storage means, and the viewpoint set for the shape data is moved or stopped. When displaying a CG image representing the inside and outside of the building on the display means, the size of the storage part is calculated based on the shape data and stored in the storage part size storage means, while the storage part is scheduled to be stored in the storage part. The area occupied by the stored item is calculated and stored in the stored item occupied region storage means, and the size of the storage portion and the stored item occupied region stored in the storage portion size storage device When the occupied area of the stored item is smaller than or equal to the size of the storage portion, a CG image representing the state in which the stored item is stored in the storage portion is displayed on the display. On the other hand, when the occupied area of the stored item is larger than the size of the storage portion, the CG image representing a state where a part of the stored item is stored in the storage portion and the remaining part overflows from the storage portion is displayed on the means. The information is displayed on the display means.

According to a fourth aspect of the present invention, there is provided a computer-readable recording medium storing a program for executing the storage planning method according to any one of the first to third aspects.

Are installed from an appropriate recording medium such as a CD-ROM. The act of manufacturing, selling, etc., a recording medium on which the above-mentioned various programs P1 to P3 are recorded is included in the technical scope of the present invention.

Prior to the display of a CG image in the display room 1, as shown in FIG.
A plan view of each floor of the house H of the customer K to be built is displayed in the right side tool display area A2 in the image display area A1 of the plan view creation screen G1 displayed on the display device 12 of the workstation 11. Tool T (button, selection field, etc.).

Although the procedure for creating the plan view will not be described in detail, the "room name" and "area" are designated using the tools T displayed in the tool display area A2, and the image display area is designated. Mouse 1 is the position where the "room" is located in A1.
The floor plan can be designed simply by designating with 4 or the like.

A storage unit built in a desired room, for example, as shown in FIG.
A storage chest 22 adjacent to the kitchen, a closet 23 under the stairs, a closet 24, 25 in the bedroom, a Japanese-style room, a closet 26 in the bedroom, a shoe closet 27 in the entrance, and a storage unit 2 for books and the like in the living room.

Note that the equipment can be arranged only by designating the "type" of the "equipment" such as furniture and electric appliances such as tables and chairs to be arranged in each room, and the arrangement position.

Since each room and equipment used in the above-described design are created in advance as three-dimensional shape data having height dimensions, only a plan view as shown in FIG. 4 is created for each floor of the house. Then, three-dimensional shape data of the house and the equipment are created, and processing such as coloring is performed on the three-dimensional shape data as necessary. 3 of the above-mentioned houses and equipment
The dimensional shape data is stored in the shape data storage means of FIG.

It should be noted that, besides creating the three-dimensional shape data of the house on the workstation 11, the drawing data (three-dimensional shape data) of the house separately created in advance by a CAD system or the like is taken into the workstation 11 and used. It may be.

Hereinafter, a procedure for examining whether the size of the walk-through and the storage unit performed when the customer K visits the display room 1 is sufficient will be described. Prior to the walk-through and the examination of the storage unit, first, the approximate quantity of the storage items owned by the entire family of the customer K is heard, and the operator S inputs it to the arithmetic processing unit 16 with the keyboard 13 or the like. .

More specifically, a plan view creation screen G1 shown in FIG.
When the user clicks on the stored item number input button B2, the screen switches to the stored item number input screen G2 shown in FIG. Here, in the stored item quantity list area A3 displayed in the lower half of the image display area A1, the operator S associates the customer K with the stored item type name stored in the arithmetic processing unit 16 in advance. When the quantity (approximate number) of the entire family is input, the quantity of the stored items for each type is stored in the stored item number storage means in FIG. These quantities will be used later when considering whether the size of the storage section is sufficient.

Further, the occupied area per unit quantity for each of the stored items, specifically, the occupied volume, is determined in advance and stored in the storage unit occupied area per unit quantity in FIG. For example, when determining the occupied volume (M / N) per unit quantity (per piece) of outerwear in clothing, a standard-sized outerwear is placed in a storage space such as a chest in which the volume M is measured in advance. What is necessary is just to calculate until the said storage part is full, to obtain the number of jackets (N sheets) when the storage part is full, and to divide the volume M by the said number N.

With respect to the storage items such as tableware other than clothes, the occupied volume per unit quantity can be obtained from the volume of the storage portion such as a cupboard and the number of tableware when the storage portion is full. The occupied volume per unit quantity is stored in the storage unit occupied volume per unit quantity.

Next, a description will be given of the principle of generating a CG image for displaying the inside and outside of the house planned to be built by the customer K on the screen 5 as a moving image or a still image as a CG image. By simplifying the three-dimensional shape data representing a house, for example, FIG.
If the viewpoint is V and the gazing point is U, the line-of-sight direction D is a direction from the viewpoint V to the gazing point U.

When generating an image when the viewing direction D is viewed from the viewpoint V as a CG image, a quadrangular pyramid E corresponding to a predetermined viewing angle is set with the viewing direction D as the center line in the horizontal direction and the vertical direction. Then, a two-dimensional image obtained by projecting an area included in the quadrangular pyramid E in the three-dimensional shape data C onto a projection plane F (a cross section of the quadrangular pyramid E) is cut out, and an image in the projection plane F (see FIG. H section) is displayed as a walk-through CG image Q on the screen 5 or the like in FIG.

The calculation for generating the CG image Q based on the viewpoint V and the line-of-sight direction D is executed by the CG image generating program P2. In addition, for example,
When the viewpoint V is advanced, the area included in the quadrangular pyramid E in the three-dimensional shape data C is reduced, so that the CG image Q depicts a state closer to the house. As described above, the inside and outside of the house are displayed as a moving image or a still image by the CG image according to the forward or backward movement of the viewpoint V or the change of the line of sight.

Hereinafter, a specific walk-through procedure will be described. When the walk-through button B3 is clicked in the tool display area A2 in FIG. 4 or the like, a walk-through screen G2 in FIG. 7 is displayed. This walkthrough screen G2
The created plan view is reduced and displayed in the sub-window A3. Here, the operator S sets the viewpoint V and the gazing point U which are the reference of the CG image generation, so that the gazing point U is viewed from the viewpoint V. In this case, the virtual image is displayed in the image display area A1 as an initial screen of the walk-through by the CG image. Here, a walk-through screen when the viewpoint V and the gazing point U are set in the living room is illustrated.

At the time of the walk-through, the operator S presses each button such as "left rotation", "right rotation", "up rotation", "down rotation", "forward", "backward" in the tool display area A2. When the movement of the viewpoint V and the change of the line-of-sight direction D are performed by, for example, appropriately clicking B4 to B9, the change of the viewpoint V and the line-of-sight direction D on the image display area A1 and the screen 5 is performed accordingly. Is displayed as a moving image or a still image by the CG image Q.

That is, when the "forward" or "back" button B8 or B9 is clicked, the viewpoint V moves forward or backward, and although not shown, the CG image Q is enlarged or reduced in the image display area A1 and the screen 5 (not shown). Will be. FIG. 8 shows a state where the viewpoint V is advanced from the state of FIG. Clicking the “left rotation” or “right rotation” button B4, B5, etc.,
Changes to the left or right, etc., and the CG image displayed on the image display area A1 and the screen 5 changes accordingly.

Next, a description will be given of a procedure for examining whether or not the storage unit of the house to be constructed, which is displayed in the CG image, has a sufficient capacity for storing the storage items owned by the customer K during a walk-through or the like. I do. In this examination, when the user clicks the storage section examination button B10 on the walk-through screen or the like in FIG. 8, the screen is switched to the storage section examination screen in FIG.

The storage unit study area A4 in FIG. 9 displays the result of calculating for each storage item whether or not the storage unit has a sufficient capacity with respect to the volume of storage items owned by the customer K. You.
For example, for books and the like, the quantity of each type of storage such as "paperback books" and "books" is read out from the storage quantity storage means (FIG. 3) and displayed in the uppermost first column L1, In the second column L2, the storage volume occupied per unit quantity of each storage item is read out from the storage area storage unit per unit quantity and displayed. For example, the storage volume occupied per unit quantity of “paperback books” is displayed as 50 cm ³ , which means that the volume occupied by one paperback book is 5 on average.
It means that it is about 0 cm ³ . These values are obtained and stored in advance.

In the third column L3, the result of calculating the storage space occupied by each storage item is displayed. For example, for "paperback", the whole of the occupied volume 2500cm ³ by the multiplication of the 50 books and the volume occupied by 50cm ³ per book quantity
Is required. The fourth column L4 indicates that the storage unit 28 for books and the like in the living room has been automatically selected as the storage unit for storing books and the like.

In the fifth column L5, the size of the storage section 28 for books and the like, here the volume, is, for example, 14400.
0 cm ³ is displayed. This volume is calculated by the arithmetic and control unit of FIG. 3 based on the area of the storage section 28 shown in the plan view of FIG. 4 and the height of the storage section 28 stored in advance. In the sixth column L6, the result of the determination as to whether or not the volume of the storage unit is sufficient to store the corresponding storage item is, for example, a symbol “○” if it is sufficient, For example, it is displayed as a symbol “x”.

That is, the total occupied volume of each storage item in the third column L3 is 100800 cm ³ ,
This value is compared with the storage volume 144000 cm ^{3 in} the fifth column L5 by this arithmetic control means. In this case, since the storage volume is larger, the storage 28 such as a book is stored in the book K owned by the customer K. Has been determined to be sufficient to accommodate the.

In the above description, the volume of the entire storage unit 28 is compared with the total volume of book-related storage items such as "paperback books" and "books". In the case where the storage area is divided into "books", the volume of each storage area may be compared with the volume of each corresponding storage item.

After the above-described determination is made, it is also possible to display in a CG image whether or not the storage section is sufficient for storing the stored items. For example, when a determination is made that the storage unit 28 for books and the like described above is sufficient to store books and the like owned by the customer K, as shown in FIG. The state stored in the storage unit 28 can be displayed as a CG image. Conversely, a determination result indicating that the storage unit 28 such as a book is not sufficient to store a book or the like owned by the customer K is lower. In this case, although not shown, a state in which a part of a book or the like overflows from the storage unit 28 can be displayed as a CG image.

In the above description, books and the like have been described. For other storage items such as clothes and tableware, the occupied volume of each storage item owned by the customer K is compared with the volume of each corresponding storage portion. Thus, the same determination can be made.
Further, in the above description, the storage items and the storage units are compared with each other by volume (three-dimensional amount). For example, for storage items that are difficult to stack and store, an area such as a finding area (two-dimensional amount) is used. ), The area of the storage unit and the occupied area of the storage item can be compared. Further, with respect to a storage item in which the depth dimension of the storage unit becomes a problem, it is possible to compare the depth dimension of the storage unit with the depth dimension of the storage item.
