三角高程测量及对向观测法的回归分析

摘要

阐述全站仪三角高程测量的3种方法,通过对精度最高的对向观测方法进行深入研究,提出全站仪三角高程测量天顶距闭合条件,建立相应的回归模型,并根据实例数据进行相应的回归分析,证明全站仪三角高程对向观测天顶距闭合条件的正确性.%It expounds on the three methods of trigonometric leveling with total-station. Based on the research on the bilateral observation, it proposes the elevating angle's closure in the trigonometric leveling, by building its regression model, and taking the regression analysis with the instance data, thus proving the validity of the elevating angle's closure.
