基于3维激光扫描技术的滑坡体地形图制作研究

采用3维激光扫描技术快速采集滑坡体地形点云信息，并提取滑坡体微地貌信息，为滑坡监测提供基础技术支持。3维激光扫描技术的数据处理主要包括外业数据采集、点云数据配准、地貌数据获取与非地貌点云数据过滤、地形图生成等过程，并着重介绍其工作原理与处理方法。采用3维激光扫描技术能够高效准确实时的监测地质灾害，对预防灾害的发生提供了决策作用。

Based on Three-Dimensional Laser Scan Technology of Landslide Topographic Map Creation Research

The point cloud information has been rapid collected by three - dimensional laser scan technology, and the landslide micro- photography information has been extracted from it. This informationprovides the infrastructure technology support for the landslide mo- nitoring. The data processing by three - dimensional laser scan technology mainly includes ： field data collection, point cloud data reg- istration, geomorphology information acquisition, non - geomorphology data filtration, topographic map creation. This paper emphati- cally introduces the working principle and processing method of three - dimensional laser scan technology. The monitoring of geological hazard is high efficient, accurate and real- time though three -dimensional laser scan technology. This method provides decision- making function for disaster prevention.
