| 摘 要： | 针对在大尺寸测量空间内进行全局测量时,存在测量范围大、精度较难控制等一系列问题,文章对全站仪构建全局测量空间的方法进行了研究。基于误差传播定律和精度匹配的原则,通过Matlab编程对全站仪构建全局测量空间的精度进行了仿真分析,分别从平面精度与高程精度的匹配、点位总精度的分布规律以及边角精度的匹配三个方面,定量分析了精度受各观测要素影响的规律,并设计了简单可行的测量方案,对Matlab仿真分析的结论进行了验证。

| Abstract: | A series of problems occurred when doing global measurement on large-scale space,such as the wide measuring range and the difficulty of precision controlling.Aiming at such issues,the method of building global measurement space based on the total station was studied in this paper.Based on the law of error propagation and the principle of precision matching,the accuracy of building global measurement space was simulated by using Matlab.The influence law of the precision affected by observation elements was quantitatively analyzed from three aspects:the matching of the plane and elevation accuracy,the distribution regularity of positional accuracy and the side-angle precision matching.Finally,the simulation results of Matlab were verified experiments. |
