IMAGE RETRIEVAL DEVICE AND IMAGE RETRIEVAL SYSTEM

摘要

PROBLEM TO BE SOLVED: To solve the problem in which there has been no useful means as means for specifying a camera position when an image photographed by a camera is transmitted/received to provide information to an operator as a technique for supporting the operator in plant maintenance or a construction site.

SOLUTION: Similar image retrieval is performed (30) on an image generated from a CAD drawing database (31) with an image photographed by a camera as a retrieval query, thereby specifying a photographing position of the camera.
