大尺寸空间中激光跟踪仪和水准仪的高程测量结果比较

Height Measurement Contrast between Laser Tracker and Leveling in Large Scale Space

随着激光跟踪仪等三维测量仪器和方法的出现,水准仪高程测量的传统地位受到较大的冲击。本文从影响两种高程测量方法精度的因素入手,分析北京正负电子对撞机的准直测量数据,着重研究激光跟踪仪在大尺寸范围内的高程测量精度。

The traditional realm of leveling in height measurement has been changed by 3D measurement instrument and the method such as laser tracker. This paper starts from the analysis of accuracy infection factor. Then, investigates the height measurement accuracy of laser tracker in large scale based on the data from alignment of Beijing Electron Positron Collider.
