摘　　要：探讨难及区域的地形数据采集方法具有重要意义。以西藏水利枢纽及配套灌区工程地形测量项目为例,介绍了地面三维激光扫描测量的前期规划设计、外业数据测量、内业数据处理等流程,检查了测量精度。结果表明,该方法可以满足地形测量要求。The discussion of the data collection methods for the hard access area is very significant. This paper uses the topographic survey project of hydro-junction and supporting irrigated area in Tibet as example to present the process flow of the terrestrial three-dimensional laser scanner, which are preliminary scheme, field data measurement and data process- ing and checks measurement accuracy. The result shows that this method can meet the topographic survey requirements.
