无人机航摄技术在四川省应急测绘保障中的应用研究

Application of Unmanned Aerial Vehicle Photogrammetric in Emergency Surveying and Mapping Support in Sichuan Province

近年来,无人机低空摄影测量技术发展迅速,已广泛应用到多个领域,其灵活机动的特点使其在防灾减灾与应急处置中的应用优势尤其突出。本文结合无人机在四川省应急测绘保障中的应用,研究应急状态下无人机航摄流程及应急影像快速处理技术,并以芦山"4·20"强烈地震应急测绘保障和四川省2013年防汛救灾应急测绘保障为例,探讨无人机航摄技术在重大自然灾害抢险救灾、灾害损失评估及地质灾害防治等领域中的应用。

In recent years,with the rapidly development of low- altitude photogrammetric,the unmanned aerial vehicle（ UAV） technology has been widely used in many fields relying on the advantages of flexibility and mobility,especially in the field of disaster prevention and emergency manage. In this paper,authors will study the flow of UAV photogrammetric and the emergency images fast-processing based on the application of emergency surveying and mapping support in Sichuan province. At last,we will take ＂ 4. 20＂ Lushan earthquake emergency surveying and mapping and 2013 flood disaster emergency surveying and mapping in Sichuan as an example,discuss the application of UAV photogrammetric in major natural disaster rescue,disaster damage assessment and geological disaster prevention.
