摘要
本文讨论了平行光管角度偏差的三种姿态,给出了计算方法。系统用SUSAN[1]算法和最小二乘法确定图像十字中心点的坐标。分别用模拟和实际图像实验,结果显示此方法精确性高。
This article discusses three attitudes of collimator,and gives aberration angle expressions.The system can figure out coordinates of cross image center by SUSAN arithmetic and least square method.Experiment indicates the method possesses high accuray.
