| Abstract: | A steel strip surface inspection system based on computer vision was presented which uses modularized frame of hardware. The software of image processing can detect and classify defects across the entire steel strip surface. The system develops an effective assembled classifier by several pattern recognition technologies including rule based table, fuzzy algorithm and neural network. It has the ability of self learning and can adapt to different equipments and materials by the training of classifier according to different sets of samples. The performance and robustness of the system is demonstrated by the experiments in steel strip production line in Bao Steel Company. |
