Abstract

An automated vision system is presented intending to detect and classify surface defects on steel strip. The framework of the system is briefly introduced and the realization, mainly focused on image processing and pattern classification, is discussed in detail. Original images of defects obtained from CCD camera are preprocessed firstly by using of DSP, which includes threshold segmentation, morphological operations, edge detection, and contour extraction. After several key features have been selected, they are inputted into fuzzy neural network functioned as classifier. The result shows that the fuzzy neural network classifier provides better classification accuracy and lower iteration times.
