Abstract: In this paper, a real-time, parameterless circle detection algorithm based on Hough transform is proposed to solve the problems of more parameters and more computation. This algorithm obtains several edge segments in the image by using ED (Edge Drawing) algorithm, and extracts the set of arc segments that may form a circle from the edge segment geometry by using line segment detector. Each pair of line segments is analyzed to determine whether a pair of effective line segments can be formed, thus generating an initial set of circles. Then the candidate circle is generated according to the geometric properties of the circle edge and verified by the reverse verification principle. The experimental results show that the proposed method can still detect the circle in the image under the interference of blur, shadow and occlusion, and the accuracy and stability of the industrial image are significantly improved compared with other algorithms.
