| Abstract: | Reviews in recent years appearance defects of domestic and foreign industrial production in the tapered roller segmentation research progress, in order to achieve a more simple and efficient roller appearance defect detection proposed a set of complete image processing algorithms. A suitable optical imaging system is designed for image acquisition, the defect segmentation of the maximum between class variance method and local threshold algorithm is proposed, and then the feature extraction and SVM classification. The experimental results show that the algorithm has higher accuracy and better adaptability than the traditional method, which can meet the requirements of industrial production. |
