摘要
分析了哈特曼(Hartmann)波前传感器传统阈值一阶矩质心算法的局限性,提出了一种改进算法,对质心探测窗口的大小先进行合理优化,再采用灰度积分图原理进行自动搜索,最后采用灰度平方加权质心算法进行质心计算。仿真分析验证了算法的可行性和优越性,有利于提高波前传感器质心探测精度。
Abstract
The limitation of traditional threshold moment centroid algorithm for Hartmann wavefront sensor is analyzed. An improved algorithm is proposed, which the centroid detection window size is optimized and searched automatic with the gray integral principle, finally uses the intensity weighted centroiding algorithm to calculate. Simulation and analysis prove the feasibility, which is beneficial to improve the wavefront sensor centroid detecting accuracy.
