摘要
传统的全站仪和GPS等监测技术对地形较为复杂、高度较高以及坡度较陡的区域来说,作业比较困难。三维激光扫描技术可以实现对物体进行高精度、高速、连续和自动三维数据获取。通过两者结合,可以高效地对目标区域表面进行三维坐标点的采集。可以完成目标区域三维模型构建、大比例尺地形图、横纵断面图、DEM模型等测绘工作,为高危边坡监测提供有效可靠的数据。
It is difficult for traditional total station and GPS monitoring technology to monitor deformation,when it comes to those complicated topography areas which has a high altitude and slope steep.3D laser scanning technology can acquire object's 3D data with the characteristics of high precision,high speed,continuous and automatic.Combination of both,it can be effective to acquire 3D data of areas we need to survey.We product 3D model,large scale topographical map,transverse and longitudinal profiles and DEM and so on through processing the scanning point cloud.These productions can provide reliable data for high risk of slope monitoring.
