A posture error compensation method of optical probe was presented in this study. The optical probe was installed on the PH10 rotating head for the scanning measurement of coordinate measuring machine (CMM).

• 针对三坐标测量机上安装激光测头时机械调整误差大以及传统补偿算法鲁棒性差的缺点；提出了三坐标测量机非接触扫描测量时PH10回转体上光学测头安装姿势误差的补偿方法；建立了安装姿势误差的数学模型.
