The invention provides a wind power rotary support surface defect detection method. According to the method, a low-angle 15-degree irradiation direction is utilized to show a texture direction. For ambient light interference, a low-angle strip-shaped light source can effectively relieve the ambient light interference. The detection algorithm combines a digital image processing method with SVM machine learning. The beneficial effects of the method are as follows: because an input workpiece image is simple in content and relatively single in color or gray level distribution, the algorithm can beused for avoiding the interference of adverse factors that the algorithm is very sensitive to noise and target size and cannot effectively cope with the condition that the image content is relativelycomplex, and has the characteristics of being simple in operation, high in speed and capable of realizing real-time processing. Besides, in some environments, if a vectorization form is used, operation circulation can be performed more quickly, and a multi-thread parallel processing method can also be easily adopted.
