该软件是针对地下导线测量的改进方法设计的，即不必在地下对全站仪进行精确的点下对中，在全站仪上安装一个偏心测量盘，通过对实际测量结果进行归化改正，从而得到理论正确的测量结果。该软件需要用户输入指定参数，如偏心距e，实际测量角度β，实际测量距离L等，从而计算出理论测量角度α和理论测量距离S(The software is designed according to the improved method of underground traverse survey, which do not have the exact point of total station in the underground, the installation of a disc eccentricity measurement by total station, based on the actual measurement results are correct so as to obtain the measurement result of domestication, correct theory. The software requires the user to input the specified parameters, such as the eccentricity e, the actual measurement angle beta, the actual measurement distance L, etc., so as to calculate the theoretical measurement angle alpha and the theoretical measurement distance S)
