摘　　要：使用地基三维激光扫描仪,采集了2013年四川芦山7.0级地震灾区农村典型民居基本完好砌体建筑物140个独立墙面的高精度LiDAR点云数据。根据标准差原理,采用统计回归分析方法,对LiDAR数据进行了处理,分析和验证LiDAR点云数据背景值区间。结果表明:芦山地区农村典型民居砌体结构建筑物墙面的LiDAR点云数据背景值区间为0~0.45 cm,并证实其合理性。Using a terrestrial laser scanner,we collect the high-precision LiDAR point cloud data of the independent walls of the barely damaged masonry structures of the typical residential houses in rural areas hit by the 2013 Lushan,Sichuan M_(S)7.0 earthquake.Then,on the basis of the standard deviation principle,and using statistical regression method,we process the obtained LiDAR data.We find that the interval of background values of the LiDAR point cloud data is 0-0.45 cm.
