摘要
结合实际工程探讨两种双测站式悬高测量方法,并对其计算原理及测量误差进行分析,解决实际工程中目标天底无法置镜和两次照准目标不统一的问题。
The author discusses two kinds of the unsupported distance measure of the double station and an alyzes the principle of the computation and the measurement error in the practical enginering. Then re solves the problem of the different results of the two aiming at the same target in the practical engineering.
