【摘要】：大型、专业的无人机遥感已开始广泛应用于大面积地质灾害调查中,本文则以近年来在三峡库区进行地质灾害应急调查的多次成功实践为基础,系统总结并建立了一套采用更加简单灵活的小型无人机遥感系统开展单体地质灾害应急调查的方法,主要包括:基于地质灾害应急调查特点定制了更具针对性和适用性的多旋翼小型无人机系统;制定了室内准备、现场作业、快速处理面处理等在内的具体实施流程;提出了像控点布设及测量、航线规划、飞行拍摄过程控制及成果处理等关键技术方法。实践表明,应用以上方法开展基于小型无人机遥感的单体地质灾害应急调查,不仅可以大大降低现场工作时间、强度以及风险,而且可以获得高精度遥感成果及信息,从而真正满足地质灾害应急调查既"快"且"高效"的客观需求。
[Abstract]:Large-scale, professional UAV remote sensing has been widely used in large-scale geological hazard investigation. This paper is based on the successful practice of geological disaster emergency investigation in the three Gorges Reservoir area in recent years. A set of simple and flexible remote sensing system of small unmanned aerial vehicle (UAV) for emergency investigation of single geological hazards is summarized and established. The main contents are as follows: based on the characteristics of geological disaster emergency investigation, the multi-rotor small UAV system with more pertinence and applicability has been customized, and the specific implementation flow including indoor preparation, field operation, rapid processing surface processing and so on has been established. The key technical methods of image control point layout and measurement, route planning, flight shooting process control and result processing are put forward. The practice shows that the above methods are used to carry out the emergency investigation of single geological hazard based on remote sensing of small UAV. Not only can the working time, intensity and risk be greatly reduced, but also the high precision remote sensing results and information can be obtained, so as to truly meet the objective demand of "quick" and "efficient" geological disaster emergency investigation.
