为了加强地形陡峭危险地区电力工程的滑坡灾害风险感知能力,提出一种基于无人机倾斜摄影测量技术的滑坡风险感知方法.计算评价因子风险概率,建立滑坡灾害风险等级评价模型,划分滑坡灾害危险等级;校正无人机倾斜摄影参数,设计滑坡灾害风险感知摄影流程,识别无人机倾斜摄影测量成果;分析地形陡峭危险地区坡度、植被覆盖度、道路距离和河流距离这4类评价因子对滑坡的影响,使用ArcGIS软件空间分析功能,综合评价研究区滑坡风险.实验结果表明,所提方法可以有效感知滑坡风险,将风险划分为低危险区、中危险区、高危险区和极危险区.
Application of UAV Tilt Photogrammetry Technology in Landslide Risk Perception
In order to strengthen the landslide risk perception ability of power engineering in steep and dangerous areas,a land-slide risk perception method is designed based on UAV tilt photogrammetry technology.It calculates the risk probability of evaluation factors,sets up the risk grade evaluation model of landslide disaster,and divides the risk grade of landslide disaster.It corrects the tilt photography parameters of UAV,designs the landslide risk perception photography process,and identifies the tilt photogrammetry results of UAV.It analyzes the impact of four evaluation factors on landslide in steep terrain and dan-gerous area,include slope,vegetation coverage,road distance and river distance,and comprehensively evaluates the landslide risk in the study area by using the spatial analysis function of ArcGIS software.The experimental results show that the design method can effectively perceive the landslide risk and divide the risk into low risk area,medium risk area,high risk area and ex-tremely risk area.
