摘要
平面控制网仿真计算在测量行业中应用广泛,如测量方案设计、平面控制网优化等,观测误差的模拟是其关键步骤。因为仪器测距标称精度与实际精度不相等,随机误差不能代表仪器实际测量误差分布规律,故采用仪器标称精度和添加随机误差的方法分别对平面控制网的边角观测值进行误差模拟的方法存在不足。为此,本文首先探讨了徕卡TS30全站仪平面测量的观测误差性质以及分布情况,然后利用统计学中假设检验的方法得其分布规律,最后通过案例分析得到一种较优的平面控制网观测误差模拟的方法。
The simulation calculation of plane control network can be widely used in surveying,such as the design of measurement program,the majorization of plane control network and so on.The simulation of observation error is the key step.The nominal accuracy of the instrument measurement is not equal to the actual precision and the random error can not represent the actual measurement error distribution of the instrument,as a result of which,the observation error of plane control network simulated by nominal accuracy of instrument and generating random error is unreasonable.Therefore,this paper first discusses the nature of the observation error of Leica TS30 total station plane measurement and its distribution,and then use the method of hypothesis testing in statistics to get its distribution law,finally through the case analysis method to obtain a better method of simulating the observation error of the plane control network.
