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 can reduce 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 preset area.

Description

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

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
