XU Ke XU Jinwu LU Shouli GUO Fang (University of Science and Technology Beijing)  
A new automatic surface inspection system for cold rolled strips based on image processing is introduced CCD matrix cameras are used in the system to capture images of strip surface, while two different illumination structures are equipped to detect different types of defects The system is peculiar in design of hardware and software, in order to assure on line inspection of strip surface Some efficient algorithms of image processing and pattern recognition for the system are presented The system has been tested with samples from a cold rolling plant. The result shows that the system can detect and classify six common defects, and the recognition ratio is close to 90 %
