为了评价飞机装配过程中大尺寸测量系统的现场测量精度,介绍了激光跟踪仪转站测量的基本原理。通过分析激光跟踪仪转站过程中的测量误差传递过程,提出对转站参数误差和转站误差的理论估计模型。该模型描述了公共观测点的配置和激光跟踪仪对公共观测点的测量误差对转站精度的影响。基于该模型,实现了对转站参数误差和转站误差的不确定度评定。利用蒙特卡洛方法对激光跟踪仪转站过程进行模拟,验证了提出的转站参数误差不确定度评定方法和转站误差估计方法的正确性。

The basic principle of coordinate system registration method was introduced in order to evaluate the measurement accuracy of large‐scale metrology system in aircraft assembly .Then an explicit model was derived to mathematically describe the transformation parameter errors and the registration error .The model reveals the impacts of the layout of the enhanced reference system ( ERS ) points and the measurement errors of the ERS points of the laser tracker . T he uncertainty evaluation of the transformation parameter errors and the estimation of the registration error were fulfilled based on the derived model . Monte‐Carlo simulation was performed to simulate the coordinate system registration process .The proposed uncertainty evaluation method and the estimation method were validated .
