Abstract: The method of image processing is used to detect the center position of the laser output spot.The algorithm is improved on the basis of the circle fitting,and then the accuracy of the spot center position is improved by image processing,de-noising,filtering and iteration.At the same time,the pretreatment and de-noising can effectively reduce the influence of white noise,salt and pepper noise in measuring,which enhance anti-jamming capability.
