| 摘 要： | 为了近距离调查高山峡谷地区崩塌地质灾害的发育情况,并快速提取灾害基本信息,利用无人机遥感对地形条件相当复杂的贵州大方县法启村火车站东侧崩塌群进行了详细的地质调查,探讨了在高山峡谷区利用地质灾害无人机遥感获取高分辨率影像的关键技术方法控制;并利用影像数据处理系统软件构建了DEM和DSM模型,通过中误差精度模型得到调查区模型陡倾坡面、缓倾坡面的平面精度分别为(0.125 m,0.170 m)、(0.052 m,0.043 m),高程精度分别为0.043 m和0.019 m,可直接提取地形地貌、地层岩性、块体运动轨迹等基本特征,作为地质灾害调查与勘查设计的基础资料,为地质灾害精准治理提供科学依据。

| Abstract: | In order to investigate the development of landslides and geological hazards in alpine canyon region at close range and extract basic information of disasters quickly,we used UAV remote sensing to survey the landslides on the east side of Faqi Village railway station in Dafang County,Guizhou Province,with complex topographic conditions in detail,and discussed the acquisition technology of geological hazards in alpine canyon region by UAV remote sensing.Then,we used the software of image data processing system to construct DEM and DSM models.The plane accuracy of the steep and gentle slopes are(0.125 nm,0.170 m),(0.052 m,0.043 nm),and the elevation accuracy are 0.043 nm and 0.019 nm,which can directly extract the basic features such as topography and landform,stratum lithology,block trajectory and so on.This study can be used as the basic data for the investigation and exploration design of geological hazards,and provide scientific basis for precise control of geological hazards. |
