备注

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 MS7.0 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.
