基于改进圆拟合算法的激光光斑中心检测

主要运用图像处理的方法来检测激光器输出光斑的中心位置,在圆拟合基础上改进了算法,加入了采集处理,去噪滤波,以及多次迭代等处理方法,提高了检测光斑中心位置的精确度,同时预处理和去噪滤波有效地减少了测量时的白噪声以及椒盐噪声的干扰,增强了抗干扰能力。

Laser spot center detection based on improved circle fitting algorithm

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.
