无人机摄影测量在北京"23·7"暴雨地质灾害调查中的应用
Application of UAV oblique photogrammetry in surveys of geo-hazard caused by"23·7"heavy rain in Beijing
摘要
Abstract
The oblique photogrammetry technology of UAV(unmanned aerial vehicle)is widely used in geological hazard surveys because of its high efficiency and strong operability.A severe heavy rain hit Beijing in July 2023 under the influence of the residual circulation of Typhoon Du Suri.Geological disasters occurred in Mentougou District due to the short-term heavy rain.Based on the UAV oblique photography technology,this paper takes Xiaolongmen Village in Mentougou District as a case to build a 3D real scene model to analyze the characteristics of geological disasters before and after heavy rainfall.The results prove that the 3D reality model can quickly understand the actual situation of the disaster area and meet the task requirements of the rapid geological disaster investigation.It can quickly master the topographic and geomorphologic changes and geological disasters before and after the heavy rain in Beijing,greatly improve the efficiency of disaster reduction,and help the application of 3D model in geological disaster investigation and monitoring.关键词
