| 摘 要： | 传统水准测量作业对前后视距差和前后视距累积差有严格要求。基于电子水准仪测量实际,提出了将水准仪的i角误差视为未知量参与水准网平差,以获得等同甚至优于视距对称条件下的水准测量精度,实现水准测量外业的简便性和高效性。具体阐述了该方法的基本原理,并结合实验进行了验证。

| Abstract: | Other than the traditional stereotype of rigid symmetry should be observed between the back and fore sight range of optical simulation leveling,the method introduced in this paper takes the level's i-angle error as an unknown variable involving in the process of adjustment.This sees no less precision of measurement or even a better one,and makes the leveling much easier and more efficient.This paper demonstrates the effectiveness of such method form the angle of physical mechanism,mathematical deduction and practical tests. |
