Description

  The present invention relates to an equipment position presentation system that searches equipment shape information recorded in a 3D CAD database based on attribute information given from outside, and generates and presents equipment images.

  In general, the 3D CAD database created in the design of facilities and buildings stores both shape information simulating actual facilities and design attributes, and is handled as an electronic model that is as accurate as the real thing and can refer to design attributes at the same time. Yes. For this reason, even in the field of actual design, it is often handled in the same way as the actual product as a compilation of the final results of the design. In addition, by using a computer, detailed confirmation can be performed on a desk in the office using 3D CAD information. Therefore, in a large-scale and complicated facility or building, it can be handled more efficiently than the actual product.

  In this way, an application system that searches for the position of the facility as one example of utilizing the 3D CAD database in which the shape of all facilities and the attribute information thereof are input and transmits the location to others is considered. A typical example of such an equipment search system is one that is used for position information transmission in cooperation with another design support system (see, for example, Non-Patent Document 1).

  This equipment search system captures equipment information stored in the 3D CAD database in the same manner as database information that stores engineering information based on character string information, and extracts the target equipment by linking them together. It is possible to display.

The 3D CAD database contains shape information simulating all equipment shapes as a compilation of designs. In general, when this is used to display the equipment position to transmit position information, the database is searched based on the attribute, and when the equipment shape is specified, it is calculated by geometric calculation from the equipment shape that meets the search conditions. Based on the position and spatial information, the viewpoint position and field of view are automatically calculated and an image is generated so that the equipment is enlarged and displayed at the center of the screen.

In many cases, it is often important to communicate the arrangement status by presenting the relationship with the equipment arranged in the vicinity. In such a case, there is a problem that even if the equipment is simply enlarged and displayed by the conventional equipment search system, the situation of the peripheral equipment is not known and it is difficult to transmit the arrangement status. Also, if the enlargement ratio is lowered so that many surrounding facilities are displayed on the screen, a problem arises in that the facilities are obstructed by other facilities.

  In other words, in the conventional equipment search system, it is difficult to automatically calculate the viewpoint position and field of view using only the equipment arrangement and shape information and display the equipment arrangement status so that it can be easily communicated to others. Accompany. For this reason, it is necessary to use a conventional facility search system for provisional display position determination, and then to make an adjustment work for generating an image usable for position information transmission by making full use of the fine adjustment function of the viewpoint position and the visual field.

  An object of the present invention is to provide an equipment position presentation system that can smoothly perform position information transmission display based on a position search result of a 3D CAD database.
