Object identifying method, apparatus, and image processing method and apparatus for object identification (Object recognizing method, apparatus, and image processing method and apparatus thereof)

摘要

The video signal representing the object output from the television camera 1 is supplied to the preprocessing circuit 3 and is subjected to binarization and block-making (low resolution), and then the image data of the area to be verified from the image data in the circuit 4 Is extracted. The extracted image data is converted into polar coordinates in the polar coordinate conversion circuit 6 including the fuzz-up table. Based on the image data after conversion, a gray level map including a radial pattern at predetermined angles is created in the circuit 7. [ The gray level map is sequentially checked against the radial pattern at the reference angle of the reference image by the fatigue pattern matching method at a predetermined angle, and a verification check reference angle coincident with the reference angle is searched. In the decision circuit 9, the target circuit and the reference image are subjected to the fatigue pattern matching process in the reference angle and the verification confirmation standard angle relationship, and a signal indicating the object identification determination result according to the matching degree is output.
