摘要：
It is presently difficult to realize automation, numerical expression and real-time processing in the measurements for center of laser concentric circles. To solve this problem, a new real-time processing method based on Gradient Hough Transform algorithm is presented, in which invalid accumulation in common Hough Transform by using gradient direction information of image edge can be greatly resolved, and the coordinates of the center of circle can be quickly detected. It is proved, for the most part, that the method can satisfy with practical application on highly precise measuring of collimation.
