全站仪三角高程测量方法及精度分析

摘要

With the rapid development of science and technology ,total station technology is more and more mature ,the precision of triangulated height measurement is improved ,and its application is expanded and deepened constantly .This paper presents three methods :one‐way observation method ,free station method ,relative observation method .Theoretically precision estima‐tion is carried out for the three methods respectively ,the main error sources of trigonometric leveling is analyzed ,and their re‐spective scope of application are summarized .%随着科技的快速发展，全站仪技术越来越成熟，其三角高程测量的精度不断提高，应用范围在不断地扩大和深化。本文介绍了单向观测法、自由设站法、对向观测法三种方法的基本原理，从理论上对三种方法分别做了精度估算，对三角高程测量主要误差来源进行了分析，并对其各自的应用范围进行了总结。
