摘　　要：对经纬仪距离、角度、斜率等测量功能的综合运用进行研究,拓展了视距法在测距方面的应用,给出了在极端或复杂情形下,实现二维水平方向或三维空间中任意两点间任意直线距离的测量方法,包括目标两点之间超视距、阻碍物多、高差大的场合,并对方法进行了验证及不确定度评定。The comprehensive application of the distance,angle and slope measuring functions of theodolite is researched,and the application of apparent distance method in distance measuring is expanded,a method of measuring the linear distance between any two points in a twodimensional horizontal direction or 3D,including,but not limited to,the over-the-horizon distance between the target points,the number of obstructions,the large difference in height,and their combination or simultaneous occurrence and the method is validated and the uncertainty is evaluated.
