| 摘 要： | 无人机摄影测量技术具有数据获取效率高、响应速度快、成果丰富多样等优势,逐步应用于地质灾害应急调查中。2020年6月18日阿娘寨滑坡复活后,采用无人机摄影测量技术进行应急调查。首先,通过检查点验证了无人机免像控摄影测量技术的可行性,总结性研究了无人机影像数据快速拼接和全面处理的软件选取,生成了调查区三维实景模型、数字表面模型(DSM)、正射影像(DOM)及密集点云等基础数据;最后对基础数据处理分析,完成了滑坡地形快速测绘、滑坡特征调查等工作,并对多期次的高精度无人机摄影测量数据进行差分计算,识别了滑坡形变较大的区域,定量表征了滑坡的形变特征,为监测仪器的选位提供了指导。滑坡体上GNSS监测的最大累计形变可达16m,将现场布设的专业监测设备的数据接入地质灾害实时监测预警系统中,有效保证了灾害防治工程的顺利实施。

| Abstract: | UAV photogrammetry technology has the advantages of high data acquisition efficiency, fast response speed, and abundant and various results, and is gradually applied to emergency investigations of geological disasters. After the resurrection of the Aniangzhai landslide on June 18, 2020, UAV photogrammetry technology is used to conduct emergency investigations. For starters, the feasibility of the drone image-free photogrammetry technology of UAV is verified by checkpoint, and the software selection of rapid stitching and comprehensive processing of UAV image data is studied in a summary. The basic data such as 3D real model, digital surface model (DSM), orthophoto image (DOM) and dense point cloud are generated in the investigation area. Based on the processing and analysis of basic data, the rapid mapping of slide topography and the survey of landslide characteristics are completed, and the difference calculation of multi-phase high-precision UAV photogrammetry data is performed to identify areas with large landslide deformation and quantitatively characterize the landslides deformation characteristics, which provide guidance for the selection of monitoring equipment. With a maximum cumulative deformation of up to 16 m of monitoring on the landslide body,GNSS is effective to ensure the smooth implementation of disaster prevention and control projects by connecting the monitoring data of the professional monitoring equipment deployed on-site to the geological disaster real-time monitoring and early warning system. |
