The Study of Neuralnetwork for Surface Inspection of Cold Rolled Sheet

The steel industry is very interested in the high accurate inspection technique of cold rolling strip because of requirement of high quality products and high speed production.Although a laser reflecting inspection system is generally used, the accuracy of inspection is not sufficient yet.We have developed new approach for a inspection method used advanced neural network technology joined with a conventional laser inspection equipment.In this paper, we show our proposed method, the performance through experiment with sample defects data and the comparison between proposed method and two conventional methods.
