摘要
本文以交会测量中的最短距离法为基础,结合误差传递定律,得出目标空间位置的测量误差公式。其间分析了两种主要的误差源——位置标定误差和角度测量误差,在目标相对基线的距离、基线长度、目标相对基线位置变化时对测量误差的影响程度;通过对交会角度与测量误差的仿真分析,提出了最小误差球及最小误差圆的概念;最后,针对双站测量时的布站,提出了一些参考性的布站原则。研究结果对双站交会测量有重要的参考价值。
In this paper,based on the shortest distance method in the intersection measurement,combined with the error transfer law,the measurement error formula of the target space position was obtained.During this period,the degree of influence of the two main error sources(namely the position calibration error and the angle measurement error)on the measurement error was analyzed when the distance from the target to the baseline,the length of the baseline and the position of the target from the baseline changed;through simulation analysis of intersection angle and measurement error,the concepts of minimum error sphere and minimum error circle werr proposed;finally,for the layout of the two-station measurement,some reference layout principles were proposed.The research results have important reference value for the double-station intersection measurement.
