This paper introduces an improved method of circle detection which is based on Randomized Hough Transform. It solves the problem of the inefficacious parameter accumulation when using randomized Hough transform to detect circles. First, construct a data space including all the edge points; Second, use the searching method to store the edge points of every connected curve in sequence; Last, choose the minimum edge-points gather from the stored edge points and get the parameters of circle basing on the character of circle. The method needs less computing quantity, and it avoids the error when solving equation groups.
