HoughCircles seems powerless when dealing with concentric circles.Like this image description,it can only detect one circle. I looked at the source code of OpenCV, for a center,it just calculate one most possible radius, so it can only detect one circle. So is there a effective method for this task?

yes, true. either try several passes with different radius, or findContours
