摘　　要：在激光准直技术的基础上,以金字塔棱镜作为合作目标,实现一种非接触式的三维小角度测量。提出了通过光斑质心位置同时求解俯仰角、偏摆角和扭转角的算法,并在此基础上设计了测量系统,完成了建模和仿真实验。实验结果表明,该方法具有工作距离远、精度高、范围适中的特点,具有良好的工程应用价值。Based on optical collimation,a non-contact three-dimensional small angle measurement method is presented by using a pyramid prism as a cooperation target.A retrieving algorithm which calculates simultaneously the pitch,yaw and roll angles is proposed according to the spot centroid.Based on this,a measuring system is designed to finish modeling and simulation experiments.Simulation experiments show that the method has the characteristics of long working distance,high accuracy and decent range,and has good application value in engineering.
