摘　　要：三维激光扫描仪在山区多地物地区进行1∶500地形图测绘时,如何从点云数据中快速获取高精度的高程和平面信息一直是测绘界研究的重点和难点,通过实验与实践,利用空间聚类理论和统计学思想,针对贵州山区野外出现最频繁的地物-田坎进行了自动化提取以及绘制研究。研究成果已经成功应用于夹岩水利枢纽工程、黄家湾水利枢纽工程中,极大提高了三维点云数据处理工作效率,具有很高的推广应用价值。The three-dimensional laser scanner is used to produce 1: 500 topographic map in the mountainous area with multiple ground object. How to quickly get high precision of elevation and plane information from point cloud data has always been a major point and a hard nut to crack in the study of surveying and mapping filed,through the experiment and practice,using the theory of spatial clustering and statistical ideas. For the ground object-field ridges that appear most frequently in Guizhou mountainous areas,the automatic extraction and mapping are studied. The research results have been successfully applied to the Jiayan Water Conservancy Project and Huangjiawan Water Conservancy Project,thus improving the efficiency of three-dimensional point cloud data processing,which has a great popularization and application value.
