滑坡灾害是危险性和破坏力均非常严重的地面灾害之一,滑坡发生后如何快速、高效和高精度地获取滑坡体的几何特征数据是滑坡应急处置重要的测绘保障工作内容。本文应用地面三维激光扫描仪(TLS)进行了快速获取滑坡区域数据和几何特征提取的科学试验,通过ILRIS_36D地面三维激光扫描仪和PolyWorks软件获取和处理数据,提取了滑坡几何特征,数据可供相关部门对滑坡灾害进行快速科学处置。该方法速度快、精度高、信息全,与常规测量方式相比具有多方面的优势。
Landslide hazard is one of the most serious ground hazards both in terms of danger and destructive power. How to obtain the geometric characteristics of landslide body rapidly, efficiently and accurately is an important work of surveying and mapping for landslide emergency response. In this paper, a ground-based three-dimensional laser scanner (TLS) was used to quickly obtain scientific data on the landslide area data and geometric features extraction. The geometric features of the landslides were extracted and processed by the ILRIS_36D terrestrial 3D laser scanner and PolyWorks software. The data were available for correlation Department of landslide disaster for rapid and scientific disposal. The method has the advantages of fast speed, high precision and complete information, and has many advantages compared with the conventional measurement methods.
