提出了一种利用激光跟踪仪进行镜面准直和姿态测量的方法, 分析了测量精度。分别利用高精度电子经纬仪与激光跟踪仪对单个立方镜和双立方镜进行准直和姿态测量, 计算固定立方镜相邻镜面夹角和双立方镜坐标系间的转换参数, 对比新方法的测量精度。同时比较测量效率、测量环境要求。实验结果显示: 比于传统镜面拟合法低于0.5′的准直测量精度, 新方法精度达到10″量级, 与主流的经纬仪方法相当; 同时, 新方法在测量效率上较经纬仪方法提高1倍以上, 对测量环境的要求也较为宽松, 在实际生产中可以代替经纬仪进行准直与姿态测量工作。

A method of laser cubic prism collimation and attitude measurement was proposed in this paper, and the accuracy was analyzed. A single cubic prism and double cubic prisms were collimated and measured respectively by using high precision electronic theodolites and laser tracker system. The angle of adjacent surface and coordinate transformation parameters were calculated, and the measuring accuracy of new method was compared. The measurement efficiency and environmental requirements was also compared. The experiments results show that the new method achieved an accuracy of 10″, which is significantly inproved compared to other traditional methods with an accuracy of 0.5′, indicating that this new method had the equivalent accuracy to other mainstream theodolite method. At the same time the efficiency of new method was improved by more than double, and the requirements for the measurement environment were also more relaxed. It could replace the method of theodolite in the actual production.
