Claims

[Claims for Utility Model Registration] An input device for inputting a registration number signal of an object to be identified that has been registered in advance, and storing shape data such as contours and feature data of the object to be identified corresponding to the registration number signal, respectively. an identification data storage device; an image display device that converts shape data stored in the identification data storage device into an image and displays the image;
The image of the shape data is reflected on a mirror surface, the image on the mirror surface is used as the positioning i-image for photographing, the object to be identified is moved to match this image, and the image is superimposed on the image and projected on the mirror surface. A superimposing optical mechanism, a photographing device for photographing an object to be identified projected on the image superimposing optical mechanism, a feature data extraction device for extracting a feature data of the object to be identified from an image signal sent from the photographing device, and an extraction of the feature data. An image matching/judging device comprising a matching/judging device that compares and matches the feature data extracted by the device with the feature data of the object to be identified stored in the identification block data storage device and outputs a decision result. (2) The image superimposing optical mechanism includes a projection lens that projects the image displayed by the image display device, a first half mirror that projects the image projected by the projection lens as an alignment image for photographing, and the first half mirror. 2. The image matching and determination device according to claim 1, further comprising a second half mirror that superimposes and projects the positioning image for photographing and the object to be identified projected on the screen for photographing. (3) The image superimposing optical mechanism is an image signal superimposing device that superimposes the image signal of the object to be identified sent from the photographing device and the shape data such as the outline of the object to be identified taken out from the identification data storage device; An image matching and determination device according to claim 1, which is characterized by having a half mirror for converting a signal into an image using an image display device and projecting the superimposed image.
