During the butting procedure of the cooperative target, the ability that circle were detected accurately in complex background appears to be very important.In this paper, in order to overcome the ergodic of standard Hough transform, an improved HT of circle detection based on locating the effective area is carried out, which could wipe off many noneffective spots.Then, sampling the edge image makes further improvement in computing speed.The experiment results demonstrate that the method is less time-consuming compared with standard HT.
