摘　　要：在精密工程测量中利用激光跟踪仪多测站测量可以快速地获得高质量的被观测对象表面点的三维坐标数据,这些不同测站观测得到的坐标需要通过坐标转换和平差归并到统一的坐标系统中。本文采用摄影测量学中的光束法平差模型,进行三维严密平差,实现多测站观测坐标数据的统一。实际观测数据处理结果表明,本文的方法可以实现此类高精度坐标观测数据的平差处理,获得较高的成果精度。In precise engineering survey,high accurate 3 D coordinates of observed surface can be captured by the multi-station laser tracker. The coordinates acquired on different stations needs to be merged into a unified coordinate system through coordinate transformation and adjustment. In this paper,the bundle adjustment method stemming from photogrammetry is used to carry out the rigorous adjustment for multi-station observed coordinates,so as to establish a unified coordinate system. The processing result shows that the method can realize the rigorous adjustment of such high precision data,and achieve high accuracy.
