电子全站仪三维方向观测法数据处理模块的研制及其应用

Development and application of the data processing module of 3D observation method of Electronic Total Station

本文简单介绍了应用三维方向观测法的背景、概念、观测方法及其计算公式,并用VB以类模块为对象变量编程,实现基于方向观测法数据处理模块的研制。利用TPS2000全站仪采集室外相机检校场标识控制点的原始数据作为本模块的应用实例,与SSoffice软件计算结果基本一致。模块数据处理的精度准确可靠,可以满足相机检校标识控制点的三维坐标精度。

This paper briefly introduces the background, principle and calculation formulaof 3D observation method and its application. Using VB class module as the object variable programming, data processing module is designed and developed. Takingthe original dataacquired by TPS2000 total station instrument from Outdoor Camera Calibra- tion identifier as examples, SSoffice software calculation results are basically the same. The precision of data pro cessing module is accurate and reliable, can meet the camera calibration 3D coordinate precision.
