Drawing information management device and comparison checking method thereof

Abstract

The present invention provides a drawing information management device and a comparison checking method thereof. The point checking personnel does not require adjusting a portable terminal, etc. to the appropriate position and orientation. Even the large-size checking object can be executed with comparison checking. The comparison checking can be executed efficiently with a view distance that canreduce the view burden of the point checking personnel. In the comparison checking method of the invention, the drawing information of the checking object is stored in a storing part. A first image which is obtained with an image shooting part and comprises at least one part of the checking object is compared with a second image that comprises at least one part of the checking object and the portable terminal thereby obtaining the position information of the portable terminal on the checking object. The drawing information of a preset area is drawn from the drawing information stored in the storing part according to the obtained position information, and is transmitted to the portable terminal so that the display part of the portable terminal displays the drawing information of the presetarea.

Description

Technical field [0001] The invention relates to a drawing information management device and a comparison inspection method. Background technique [0002] In the past, in the inspection of the configuration, type, quantity, etc. of components installed in inspection objects such as computer products, buildings, automobiles, and airplanes, such as figure 1 As shown, the inspectors perform comparative inspections by alternately observing and comparing drawings such as installation drawings, structural parts tables, display drawings, and the inspection objects. In recent years, there has been a demand for the development of a collation inspection method that reduces the visual burden of the inspector in the collation inspection (that is, the inspector can shorten the distance between the viewpoint of the inspection object and the drawing surface). [0003] For example, in the method described in Patent Document 1, in order to reduce the visual burden of the inspector during the collati...

AI Technical Summary

Problems solved by technology

[0005] However, in the conventional collation inspection method (Patent Document 1, etc.), although the visual burden of the checker in the collation inspection can be reduced, the inspection object is limited to the substrate of a relatively small computer, and there is a problem that the inspection object is relatively large In the case of substrates and large devices (such as airplanes and automobiles), there is a problem that it is necessary to prepare a large display screen of the actual object size of the inspection target

In addition, in the conventional comparison inspection method, in order to make the inspection object overlap with the picture on the display screen, the inspector needs to adjust the inspection object or the display screen to the appropriate position and orientation, so it takes time in preparation, and it is time-consuming in comparison inspection. There are problems with the efficiency of

That is, for example, there is a problem that after the inspector displays the picture of the inspection object on the display screen, the inspection object placed on the back side of the display screen needs to be moved.

In addition, when the inspector moves the display screen to the position of the next inspection object for comparison inspection, it is necessary to select a picture corresponding to the inspection object placed on the back of the display screen to be displayed on the display screen. Operate such problem points
