Description

  The present invention relates to a building renovation design support system.

When designing a renovation, a field survey of the target property is an indispensable matter and takes time and effort. For example, in a conventional business model for renovation design, a person in charge first performs a field survey to acquire current building information such as necessary dimensions and floor plans. After that, it was a time-consuming process to return to the company, create a renovation plan from the current building information, and go to the site again to make proposals to the owner. Several techniques have been proposed for carrying laptop computers and scanners, sending local information to a company server, etc., and improving them (see, for example, Patent Document 1).
JP 2005-301358 A

However, the above-described conventional technology reads handwritten or printed paper information with an optical imaging means such as a camera. However, field surveys are often performed outdoors and are not always a good shooting environment. For this reason, noise caused by various disturbances such as external light is mixed in the photographing information, reading errors of information such as characters and symbols indicating dimensions and members occur, and only photographing information insufficient for 3D model creation is obtained. It may not be possible. Recently, the demand for remodeling and seismic diagnosis specialized in seismic reinforcement is increasing rapidly. However, in such applications, more detailed numerical information is required, and it is usually installed in mobile phones. In many cases, it is not possible to obtain sufficient shooting information by using a camera. For example, “detailed information for each member” (for example, wall thickness, number and dimensions of columns, reinforcement members for joints, etc.) is also necessary for the accurate implementation of seismic reinforcement reform proposals and seismic diagnosis. Information must be read accurately even in the environment. Also, in the field survey in the room, it is necessary to investigate and record the members and dimensions such as the attic and under the floor. However, there may be a case in which reading failure occurs in the severe environment described above. Further, since the above-described conventional technology does not support earthquake-resistant reforming, there is a problem that an expensive earthquake-resistant design support software system for earthquake-resistant analysis is necessary.
Therefore, an object of the present invention is to provide a renovation design support system that can acquire information sufficient for renovation accurately on the spot and provide a quick client service on the spot with a very simple system / apparatus.

In order to solve the above-mentioned problems, the building renovation design support system according to the first invention is:

Therefore, it is possible to obtain photographing information sufficient for creating a 3D model. In addition, it is possible to accurately read more detailed numerical information in remodeling specialized in seismic reinforcement and seismic diagnosis. In addition, a general consumer can easily and quickly obtain a two-dimensional diagram generated by a full-fledged CAD system, and the consumer can promote reordering and increase sales opportunities.

Read (step C10). The read information is transferred from the digital writing instrument to the portable terminal. When there are a plurality of floors such as a two-story building, a plan view of each floor may be included in the same drawing, or may be described separately in separate drawings and the same acquisition may be repeated. Next, the acquired current building information such as numerical information and floor plan information is converted into vector data using a calculation means (C12), the vectorized data is corrected (C13), and the data including 3D A request to be modeled is transmitted to the server (C14).

  On the server side, the request transmitted from the client is received (step S10), and a 3D model is created by high-speed computing means based on the current building information converted into numerical information or vector data included in the request (step S10). S12). Next, several 2D maps are generated from the 3D model based on the current building information (S13), that is, the 3D model is converted into several 2D maps. Next, an earthquake resistance analysis is performed from the current building information (step S14). Then, the 3D model, 2D diagram, and seismic analysis information are transmitted to the client via the network.

  On the client side, if the computing means of the client is fast enough to convert the 3D model into a two-dimensional CG, the client receives the 3D model from the server (C16) and generates a two-dimensional diagram based on this.

When generating a 2D diagram, default information is set in advance for members and dimensions such as roofs, walls, floors, exteriors, interiors, floor heights, and ceiling heights. To create a two-dimensional diagram. Furthermore, when the floor plan is only a wall line, default values of openings, joinery, and columns can be set in advance, and a two-dimensional diagram in which these are automatically added can be generated. As this additional information, numbers, codes, symbols and the like described in the drawings may be read, or a user may input them separately. Alternatively, the user can modify these data after viewing the generated two-dimensional diagram. Next, the two-dimensional diagram generated by the client or the two-dimensional diagram generated by the server is displayed, or the 3D model is displayed on the screen by wire frame and rendering (that is, three-dimensional CG). The user accesses the server via the network using the client and browses the member database (provides the member data on the server side (S16)), and the user refers to various data such as the appearance and price of the member. A desired member is selected using input means (instruction means such as a numeric key, a keyboard, a mouse, and a cross button) (C24). Next, estimate information is generated based on the selected member (C26) and displayed on the screen (C28). The two-dimensional diagram is updated based on the selected member (C30), the updated two-dimensional diagram is displayed on the screen, and the seismic analysis information is also displayed (C40).
