浅谈无人机在地质灾害应急调查中的应用——以四渡河滑坡、大石地崩塌调查为例

Application of UAV in the Emergency Investigation of Geological Disasters-A Case Study on the Siduhe Landslide and Dashidi Collapse,Beijing

通过对北京市怀柔区四渡河滑坡点及密云区大石地崩塌点的应用模拟试验,分析了多旋翼无人机在地质灾害应急调查中的使用方法和无人机建模软件基本功能及其相关使用技巧,并探讨如何利用现有软件中的相关功能对无人机影像数据及其三维模型进行案例分析,为无人机在地质灾害应急调查中的应用提供实际案例,以期为无人机开发更多的软件和功能将其更充分的利用到地质灾害应急调查或地质灾害常规调查中,也为无人机地灾调查应用体系的建立提供更多的素材。

Through the application simulation test of Siduhe landslide point in Huanrou District and Dashidi collapse point in Miyun District,Beijing,this paper analyzes the application method of multi-rotor UAV(unmanned aerial vehicle)in emergency investigation of geological disasters,the basic function of UAV modeling software and related application skills.In order to provide practical cases for the application of UAV in emergency investigation of geological disasters,this paper also discusses how to use relevant functions in existing software to analyze UAV image data and its 3D model.We expect to provide more materials to develop more software and functions,to make full use of geological disaster emergency investigation or traditional geological disaster investigation,and to enrich the application system of UAV for ground disaster investigation.
