摘要
三维激光扫描技术作为高清晰测量,具有非接触、采样率高、高分辨率、高精度、全数字特征、高效率、穿透性和可直接生成三维空间成果等优点,特别适合在地质灾害监测中应用。文章利用三维激光扫描技术对滑坡监测体进行点云数据采集,再从监测点、断面线和三维模型三个维度对点云数据进行分析,提供整体与细节兼顾的高精度成果及信息,从而更好地满足地质灾害监测的需求。
As a high-definition measurement,3D laser scanning technology has the advantages of non-contact,high sampling rate,high resolution,high precision,full digital characteristics,high efficiency,penetrability and direct generation of 3D space results,which is especially suitable for application in geological disaster monitoring.The point cloud data of landslide monitoring body is collected by using 3D laser scanning technology.Then,the point cloud data is analyzed from three dimensions of monitoring point,section line and three-dimensional model,which provides high-precision results and information with overall and detailed consideration,so as to better meet the needs of geological disaster monitoring.
