| 摘 要： | 对边测量是全站仪的一种专项测量功能,它可用来间接测量两个不可通视点之间的水平距离。该方法设站灵活,操作简单,但其测量精度没有标注,需要通过计算求得。本文根据全站仪对边测量的基本原理,推导出对边测量的精度计算公式,通过实例计算,对其精度进行了分析,讨论了对边测量在测站改变时其精度变化的规律,提出了提高对边测量精度的方法。

| Abstract: | The RDM is a kind of expert measure function of Electronic total station, it can indirectly measure level distance that two point cannot be seen directly, and the method is flexible for seting up station and simple for operating. Because its accuracy isn't marked, it needs to be calculated. According to the basic principle of RDM with electronic total Station, this paper obtained the calculating formula of accuracy for RDM and verified the formula and analyses its accuracy by the examples, discussed the rule of RDM's accuracy change which is responsible to the observation station's change,and found a way to enhance Accuracy of RDM. |
