  According to the present invention, based on a floor plan of a building created using CAD (Computer Aided Design), the room center of gravity coordinates of the plan and the center of gravity range that is an allowable error with respect to the center of gravity are obtained, and the data to be searched together with the plan And, in comparison with the center of gravity range calculated based on the zoning information input arbitrarily and the center of gravity range related to the data, the floor plan related to the search target data satisfying a predetermined precision is extracted It is.

Conventionally, floor plan search for buildings using a computer system is a database that stores standard plans, and on the other hand, the floor plan desired by the operator is conditionally set and input as search target data. The search target data that satisfies the conditions is extracted from the database.
Specifically, for example, in the database storing the standard plan, the floor plan is set for each standard plan, such as 2LDK and the entrance position is south, while the search target data is the floor plan desired by the operator. Whether it is 2LDK or 3LDK, and whether the entrance position is in the east, west, north, or north direction, conditions are set by individually specifying search items. From the standard plans accumulated in the database, A standard plan that satisfies the conditions is extracted.

  FIG. 1 is a block diagram of a building plan search system according to the present invention. In the system according to the present invention, the storage device (2) is connected to the programmed main control unit (1) for controlling the system, and the main control unit (1), as shown in FIG. Are connected to an input device (3) composed of a pointing device such as a keyboard and a mouse, a display device (4) for monitoring input data and a search result, and an output device (5) for outputting the search result.

The main control unit (1) is necessary for operating a control program such as an OS (Operating system) and various means for causing the program according to the present invention to function, as well as a program and a system that define the processing procedure of the means. Various means are stored.
In addition, other components such as an internal memory for temporarily storing various data and hardware and software necessary for operating the computer system and executing the program are naturally included.

  Note that the present system is not limited to the above configuration, and may be another known configuration. That is, a program or a file related to the present system is recorded on a computer-readable recording medium such as a CD-ROM and can be installed and used on another computer, or a distribution server device can be used to request a distribution destination. Depending on the situation, it is possible to download a program or a file related to the present system to a memory of another computer via a network, or to use only the function.

  In the following description, the floor plan created by the CAD to be searched is referred to as plan A, and the floor plan to be searched by the operator is referred to as plan X.

  The “room center-of-gravity coordinates” described in claim 1 and other claims is obtained by coordinate-converting the center of gravity (P shown in FIG. 4) of each room of the plan in the floor plan A (FIG. 3) created by CAD. Is. The room center-of-gravity coordinates are automatically calculated by the room center-of-gravity coordinate calculation means constituting the present system when the floor plan is stored, and are stored in the storage device (2).

  The “allowable error with respect to the center-of-gravity coordinates” described in claim 1 and the other claims is set by giving a constant width (Q) to the room center of gravity (P) according to plan A as shown in FIG. Refers to the center of gravity range (S). At the time of search, if the center-of-gravity coordinates (seconds) related to the search target data specified by the operator, which will be described later in detail, are included in the center-of-gravity range, processing is performed as conforming.

“Zoning” in claim 1 and other claims refers to a floor plan desired by the operator, and as shown in FIG. 6, is an area specified by an input device (3) comprising a pointing device such as a mouse. (Exhibit A).
In addition, the “system that can input zoning” according to claim 1 refers to a system that can input the area designation by drawing the zoning (step A) (FIG. 6). A computer system having a configuration separate from the CAD to be created, and the zoning information and the floor plan between the zoning information input by the system and the floor plan created and accumulated by the CAD The system configuration allows information comparison and examination.

  The “accuracy rate” described in claim 1 and other claims refers to the number of barycentric coordinates of each room of the floor plan A among the barycentric coordinates (b) of each room related to the plan X as the search target data. It indicates whether it is located within the center of gravity range (S). For example, if three of the five rooms of Plan X are located within the center of gravity range (s) of Plan A, the relevance rate is 60%.

The “acceptance rate setting unit” described in claim 2 and other claims is a unit that can arbitrarily set how many percent or more of the plan A to be displayed is displayed when the search result is displayed. If the accuracy rate is set to 60%, but no plan A that satisfies the accuracy rate has been extracted, if it is set to 55% by the accuracy rate setting means, it is close to the floor plan desired by the operator. It is possible to extract some floor plan A.
Conversely, when a large number of plans A satisfying 60% are extracted, it is possible to search efficiently by resetting the relevance ratio to 65% and 70%.

The “precision matching means” described in claim 2 and other claims will be described.
A large number of plans A are stored as search target data, and when the search process is executed with the plan X as a search target, the relevance ratios are calculated individually for the plans A-1 to An. Then, under the comparison of the individual relevance ratios and the set relevance ratios, only the plan A having the relevance ratio satisfying the set value is obtained as shown in FIGS. 9 (a) to 9 (b). It will be extracted as a floor plan.
It is also possible to convert the center-of-gravity information of the relevance ratio satisfaction floor plan into zoning.

  In addition to the above, for example, it is possible to set a plurality of relevance ratios, display the number of hits for each relevance ratio, or provide a range for the relevance ratios and have a relevance ratio of 70% to 80%. By making it possible to extract Plan A, or by specifying the positional relationship between specific rooms as a priority condition separately, the accuracy rate does not satisfy the set value, but if there is a plan that satisfies the positional relationship, It is good also as giving the function of making it hit and extracting.

A first embodiment of the present invention will be described with reference to FIGS.
The present embodiment relates to a technique for searching a floor plan for a building plan, and for searching for a floor plan that meets the floor plan conditions desired by the operator from various floor plans that have already been created and stored by CAD. It is. In this system, it is a designer who creates a floor plan using the CAD function, but an operator who performs a search operation is a designer, a customer, a coordinator, or the like.

  In the figure, (1) is a main control unit, (2) is a storage device, (3) is an input device, (4) is a display device, (5) is an output device, and (P) is the center of gravity of each room of Plan A. , (Q) is the center of gravity range of each room of Plan A, (S) is the tolerance from the center of gravity of each room of Plan A to the center of gravity range, (A) is zoning of Plan X, (O) is zoning of Plan X Is the center of gravity.

  Prior to performing a search, various floor plans are created by the CAD function of this system (S101, FIG. 3), and are stored in the storage device (2) as search target data (S102). At this time, the center-of-gravity coordinates of each room of the floor plan is automatically calculated by the room center-of-gravity coordinate calculating means (S102a, FIG. 4), and the identifier for specifying the type of the room is associated with the floor plan, and the storing means Is stored in the storage device (2).

The input of the search target plan will be described. The operator inputs a plan to be searched which is a floor plan desired by the operator, that is, plan X. When starting the search (S103), the operator name, family structure, and other basic information such as the planned construction site are registered if possible, but this is not an essential requirement in this embodiment.
Next, as shown in FIG. 6, the zoning input means of this system designates the floor plan area imaged by the operator as a zone (FIG. 6) and inputs it to this system (S104). Although not described in detail, at the time of zoning input, the room type such as “Japanese room” and “entrance” is also input by the input device (3) for each zoning, and one room type is specified for each zoning by inputting the room type. To be attached.
In the present embodiment, the plan relating to the input zoning information is hereinafter referred to as plan X-1.

With respect to the identified plan X-1, the system calculates the coordinates of the center of gravity (B) for each zoning by the center of gravity coordinate calculation means (S105). Then, the calculated center-of-gravity coordinates are used as search target data, and are temporarily stored together with an identifier assigned based on the specified room type at the time of zoning input (S105).
Next, a search is performed by the system by clicking a search execution button (not shown) shown on the display device (4) (S106).
Then, in response to the execution instruction, the present system searches the existing floor plan A stored in the storage device (2) as a search target (S106).

  Here, a plurality of search target data such as plan X-2, plan X-3... May be created, and one plan X may be specified by the search target data specifying means at the time of search (S104). .

  In the search, the centroid range (Q) is defined as a constant value as an allowable error in advance with respect to the room centroid coordinates related to the search target data. It may be changed by setting means.

  In this embodiment, since all the stored plans A are to be searched, when the search start button (not shown) is clicked after the barycentric coordinates of the plan X-1 are calculated, this execution is performed. In the example, plans A-1 to Plan An that are all plans to be searched are sequentially extracted, and the center of gravity range (S) for each room of each plan A and each room of the plan X-1 are extracted. The center-of-gravity coordinates (B) are compared by the center-of-gravity comparison means based on the same identifier indicating the room type, and the relevance ratio is calculated for each plan A by the relevance ratio calculation means (S106a).

  After all the relevance ratios from plan A-1 to plan An are calculated, as shown in FIG. 9A, a predetermined relevance ratio (in this embodiment, 55% is set in advance). The number of plans A that satisfy the condition is displayed on the screen.

Then, when displaying the list of the results, clicking the “view list” button in FIG. 9A displays a list of each plan and the relevance ratio of the plan (FIG. 9B). . When a specific plan A-1 is selected from the list, details of the relevance ratio relating to the plan are displayed as shown in FIG. 9C. Furthermore, when displaying the details of the floor plan of the plan A-1, clicking the “display plan” button in FIG. 9C, a specific floor plan as shown in FIG. 3 is displayed on the screen. Will be displayed. In addition to displaying it as a floor plan in plan, it may be displayed three-dimensionally with CG.
In addition, it is good also as displaying by the zoning converted from the gravity center information of a floor plan.

As described above, according to the present embodiment, since it is possible to display at the relevance rate, as in the past, in the search system that remains whether or not it hits, that is, whether or not there is a floor plan desired by the operator. Compared to the above, it is preferable because the range of use of search results is greatly expanded.
Furthermore, it is possible to perform efficient searches that take into account the positional relationship by simply zoning and inputting the desired rooms adjacent to each other, and dramatically improve operability and search capabilities compared to conventional search systems. It became possible.
By simply inputting the zoning according to the image that the customer has with respect to the floor plan, it is possible to check with the floor plan and CG, and the spatial image can be easily grasped. Can be expected to lead to orders.

  A second embodiment of the present invention will be described with reference to FIG. FIG. 10A illustrates an example of a screen displaying search results according to the second embodiment, and FIG. 10B illustrates an example of a screen displaying a search result list according to the second embodiment. .

  The present embodiment relates to a technique for searching a floor plan for a building plan, and for searching for a floor plan that meets the floor plan conditions desired by the operator from various floor plans that have already been created and stored by CAD. Thus, the present invention relates to a technique for setting a plurality of relevance ratios and displaying and outputting search results according to the relevance ratios.

  From the creation and storage of Plan A to be searched and the calculation and storage of the center of gravity coordinates of the room for the plan, the operator inputs the desired floor plan using the zoning input means (S104), and the center of gravity coordinates for the zoning are entered. The process up to the calculation (S105) is the same as in the first embodiment.

  After the operator inputs a desired zoning (S104) and the system calculates the barycentric coordinates related to the zoning (S105), the operator sets a plurality of matching ratios. In this embodiment, “60%” and “50%” are set. At this time, although not shown, a desired relevance ratio can be set by the input device (3) on the operation screen shown on the display device (4) constituting the system. The system receives the setting process, and displays a search result based on the set relevance ratios in the subsequent search process.

  In this embodiment, a desired floor plan (hereinafter referred to as plan X-2 in this embodiment) input by the operator is input by the zoning input means (S104), and the center-of-gravity coordinates related to each zoning is calculated by the calculation means ( S105). In addition, by specifying the room type for each zoning when inputting the zoning, the system assigns an identifier to each zoning and temporarily stores it as a search target plan in association with the barycentric coordinates (S105).

  Next, when the search is executed (S106), the plans A-1 to Plan An stored in the storage device (2) are sequentially extracted as the search target data, and the center of gravity range related to the plan A is obtained. Recognized and compared with the barycentric coordinates related to the plan X-2, which is the search target data, is compared by the barycentric comparison means, and the relevance ratio is calculated for each individual plan A by the relevance ratio calculating means (S106a ).

In this embodiment, the plan A corresponding to the relevance ratios “60% or higher” and “50% or higher” is extracted and displayed as a search result as shown in FIG. 10A (S107). .
Here, in this example, since seven building plans with a compliance rate of “50% or more” were hit, when the “List” button was clicked to display a list related to the result, The items are displayed in order from the highest or lowest (FIG. 10B).
Note that, when the relevance ratio is changed according to the search result, it can be changed to a desired relevance ratio by clicking the “change relevance ratio” button shown in FIG.
In addition, as shown in FIG. 10B, when the precision to be displayed is to be changed, a search result list based on the precision can be displayed by clicking a desired precision from the pull-down menu. It becomes possible.

Furthermore, when it is desired to display a specific plan A from the search result list screen, a detailed floor plan related to the plan can be displayed by clicking a display indicating the plan.
Further, as in the first embodiment, the floor plan may be displayed by CG or by zoning converted from the center of gravity information of the plan.

  As described above, according to the present embodiment, it is possible to perform an efficient search by setting a plurality of relevance ratios in advance, which is more preferable.

  A third embodiment of the present invention will be described with reference to FIG. FIG. 11 is a diagram illustrating an example of a screen displaying search results according to the third embodiment.

The present embodiment relates to a technique for searching a floor plan for a building plan, and for searching for a floor plan that meets the floor plan conditions desired by the operator from various floor plans that have already been created and stored by CAD. Thus, the present invention relates to a technology related to a search system that makes it possible to search for a plan that satisfies a desired relevance ratio, while preferentially extracting a plan that satisfies a specific condition.
The system according to the present embodiment is not different from the above-described first and second embodiments, except that a system that can preferentially extract a plan that satisfies a specific condition.

  “Precisely extractable” means, for example, extracting preferentially that two specific rooms are adjacent to each other, and extracting a plan satisfying a predetermined conformity rate and satisfying the priority condition. It is possible.

  In specifying the priority condition, in this embodiment, in addition to the means described in the first and second embodiments, the priority condition specifying means and a plan satisfying a predetermined conformity ratio are specified. It is assumed that there are specific condition recognition means and specific condition extraction means for recognizing a plan having priority conditions. Of course, means for displaying and outputting the extracted plan is provided.

  For example, when the priority condition is that “Japanese-style room” and “Living Dining (LD)” are adjacent, the priority condition specifying means specifies that the two rooms are adjacent at the time of zoning input. Two rooms are treated as one room. Specifically, for example, a specific identifier indicating adjacency is added between an identifier indicating “Japanese-style room” and an identifier indicating “LD”. On the other hand, from the plan A satisfying the predetermined conformity rate, the judgment whether or not “Japanese-style room” and “LD” are adjacent is recognized by the specific condition recognition means, and only the plan is extracted separately. (FIG. 11).

  According to the present embodiment, not only a plan satisfying a predetermined relevance ratio but also a condition that the operator particularly desires can be preferentially searched, so that a more effective floor plan search can be performed. It goes without saying that the floor plan may be displayed by CG or by zoning converted from the center of gravity information of the plan.

  The system and method for searching based on zoning input and centroid information are not limited to those related to the floor plan, and if the area can be specified and the centroid information based on each area can be obtained, the data to be searched and the search target It can be specified as target data, and can be widely applied as a search means. For example, in the case of housing, the present invention can be applied to scenic spots and exteriors, and can be applied to other uses such as searching based on past arrangement information when examining individual arrangements.
