Title: Body recognizing apparatus
Inventor: KAHARA KEIJI
IPC: G01B11/245
Filed: 1988-12-27
Abstract: PURPOSE:To make it possible to compute the position of a body accurately by recognizing one of the bodies based on the width and the height of a part where a slit image is shielded with the body, and obtaining the coordinates of the body based on the inclinations and the distances of two cameras when the reference image is cut. CONSTITUTION:Bodies to be recognized 12a-12d are mounted on a horizontal stage 10. An irregular reflecting surface 14 is arranged at the rear side, and a means 16 for projecting multi-slit light beams is arranged. A slit image 18a on a reference surface 30 on the irregular reflecting surface is shielded with the body. The width (d) and the height (h) of the shielded part are obtained with a camera 20. The image is processed in an image processor 22. The result is compared with the shape data of the bodies 12a-12d which are stored in the memory of a computer 24. Thus one of the bodies is recognized. Then, the coordinates of the center of the body are obtained by a specified computing expression based on the inclination of the recognized body with respect to the optical axis of the camera and the distance between both cameras by using the coordinates of two cameras where the image 18a of the slit image on the reference surface 30 is cut.
