目前,由于光电测距仪的发展和在工程勘测单位得到比较广泛的使用,研究用光电测距高程测量代替几何水准测量的方案就显得非常必要。国外对光电测距高程测量的理论分析已有不少文献可供参考。国内也有一些单位作过试验。对于光电测距高程测量的精度及代替
At present, due to the development of photoelectric range finder and its widespread use in engineering survey units, it is very necessary to study the scheme of measuring optical elevation distance measurement instead of geometric leveling. There are many references for the theoretical analysis of photoelectric distance measurement abroad. Some domestic units have also been tested. Accuracy and replacement of photoelectric distance measurement
