摘 要: In view of the disadvantages of manual testing of bearing surface defects in the bearing production process, an automatic detection and identification method of bearing surface defects based on machine vision is proposed. Firstly, the source image is pre-processed by gamma correction algorithm, and the Canny algorithm is improved by adaptive selection of the Canny algorithm based on iterative threshold segmentation method and Ostu algorithm to improve the integrity and precision of the segmentation of bearing surface defects. The experimental results show that the method can be accurately detected of bearing surface defects, and the defect recognition rate has reached 93.33%.

鉴于轴承生产过程中人工检测轴承表面缺陷存在诸多不足,提出了一种基于机器视觉的轴承表面缺陷自动检测与识别方法。首先,对源图像进行伽马校正算法预处理,并通过迭代阈值分割法和Ostu算法对Canny算法进行自适应优化,以提高轴承表面缺陷的分割完整性与精度。实验结果表明,该方法能够准确检测轴承表面缺陷,缺陷识别率达到93.33%。
