【Abstract】 In the paper, the significance of automatic recognition and classification of surface defects for steel plate in hot-rolling process is stated at first based on the production status of steel plate in China. Then the classification, attributes and occurrence reasons of the surface defects are analyzed in depth. Furthermore the surface image processing and feature extraction for steel plate with defects are studied. Finally, the automatic recognition method and the design of classifier are discussed, and a practical solution scheme for the automatic recognition and classification of surface defects for hot rolled steal plate is suggested, and its implementation is being carried out.更多还原
