Applications of machine vision in industry inspection and its research

Based on a model of machine vision technique, the paper puts forward a method of high accuracy camera calibration for the system of machine vision inspection. Key techniques in this system include the camera calibr- tion, curve inspection and feature matching, etc. According to thesis of "form much to one", the paper discusses an improved method of Hough transform. In light of the theory of constrain, it also gives a method of feature match -ing. These methods have been proved by corresponding experiments, and some of them have been successfully uti- lized in the inspection of complex industrial parts.
