Sheet metal part quality detection method

The invention relates to the technical field of image data processing, in particular to a sheet metal part quality detection method. According to the method, an industrial camera is used for acquiring grayscale image data of a sheet metal part, and an image data processing method is improved: a grayscale image is subjected to regional division according to a result obtained through edge detection, then an illumination component of each pixel point under the condition of only illumination is obtained through Gaussian filtering processing, and the difference between the grayscale value of the pixel point in each region and the corresponding illumination component is determined; according to the method, region classification delimitation is realized, the abnormal degree is acquired by combining the position distribution of the connected domain and the difference degree of the pixel points, the enhancement coefficient of the pixel points is acquired according to the gray difference and the abnormal degree to enha
