Abstract: In the automobile components detection for the actual needs, the analysis of the basic Hough transform and random Hough transform for circle detection technical characteristics, it improves the basic Hough transform algorithm. Using Sobel operator to extract image edge, and circular range of parameters prior knowledge is used to determine the region of interest and the range of radius, so the calculation is greatly reduced, thus realizing the rapid detection of the center coordinates and radius, and it meets the real-time requirements of industrial production.
