利用三维激光扫描技术动态监测沟蚀发育过程的方法研究
Methodology of Dynamic Monitoring Gully Erosion Process Using 3D Laser Scanning Technology
摘要
Abstract
This paper introduced the basic principles of laser scanning technology（LIDAR）,and specified the method of application the LIDAR to dynamically monitor gully erosion processes,which included measuring preparation,scanning survey process,point cloud pre-processing,coordinate transformation,TINs generation and soil loss estimation.Taking the experimental study on the gully erosion processes by simulating rainfall as a study case,dynamic monitoring method of gully erosion process using LIDAR was described in detail,which comprised field data collection,point cloud analysis,and mesh modeling.Comparison of the measured soil loss and the estimated soil loss showed that LIDAR technology has high accuracy to monitor soil erosion,and the estimating accuracy reaches to 96.85%.It suggests that the LIDAR should be combined with GPS technology to monitor gully erosion in field experiment.关键词
