全站仪轴线误差分析与改正计算

针对全站仪的轴线(视准轴、横轴、竖轴)和反光镜轴线固有的几何关系对角度观测和距离观测具有一定的影响,找出变化规律,明确影响程度,并给出相应的补偿和改正方法,为提高全站仪测角、测距的精度提供了理论依据,对生产实践中根据精度要求合理选择补偿和改正选项具有指导意义。

Analysis and correcting computation of axis line error for the electronic total station observations

The geometry relation of three axis lines(axis of collimation,lateral axis,vertical axis)and the axis line of range finder prism certainly have influences on the angle and distance survey.It supplies the theoretical base for improving the accuracy of the electronic total stations measuring angles and distance to find the principle of changing and clarify the extent of influencing.It also provides the guidance for reasonably choosing the item of compensating and correcting according to the requirement of accuracy in practice.
