加密控制点的稳定性分析

The analysis of the stability of endensed control point

为了判定加密控制点的稳定性,本文提出了以加密控制点两期测量坐标值之差异为统计检验量,采用t检验法来进行位移显著性的检验方法。最后,通过算例说明了此方法的具体应用。

In orde to judge the stability of the endensed control point, this paper points out that we should use the differences between the values of coordinates of two surveys as the statistical testing point and adopt t - testing method to test the significance of displacement. In the end, this paper demonstrate bow this method is appleied with examples.
