基于UAV倾斜摄影技术的泥石流迹地探测试验应用

Investigation and Application of Debris Flow Hazard Based on UAV Oblique Photography Technology

作为是一种新兴的高新技术,UAV倾斜摄影测量技术因其优势,应用领域很广。选择东川小江支流的小白泥河泥石流迹地为试验研究案例,通过应用倾斜摄影技术采集野外数据,并获得泥石流沟谷的三维数据模型,结合DOM及DEM数据分析,利用Arcgis10.2软件处理小白泥河泥石流迹地试验案例数据及特征解译,验证UAV倾斜摄影测量技术在泥石流沟谷中应用的可行性与先进性。该技术在今后的地质灾害调查中具有重大的战略意义。

UAV oblique Photogrammetry Technology is a new high-tech, because of its advantages, solid and application of the field is very wide, this paper applies it to the Xiaobaini River Zhigou mud-rock debris flow disaster investigation, which plays a vital role in the data analysis, through the oblique photography obtained three-dimensional data model, Dom data and DEM data are used for data processing and interpretation using software such as Arcgis10.2, which proves the feasibility of the technology and has great strategic significance in the future geological hazard investigation.
