无人机低空摄影测量系统在地质灾害应急中的应用研究——以云南洱源特大山洪泥石流为例

摘要

无人机低空摄影测量技术在近几年取得了巨大发展,从理论研究已经进入到实用化阶段,尤其是在预防与应对自然灾害方面有着明显优势.本文以无人机低空摄影测量系统在云南省洱源县炼铁乡和凤羽镇因暴雨引发特大山洪泥石流地质灾害应急抢险中的应用为例,介绍了无人机低空摄影测量系统的核心功能、优势和技术特点以及无人机低空摄影测量系统在地质灾害应急调查与监测中所发挥的重要作用.%In the recent several years, Unmanned Aerial Vehicle photogram metric system have made great development from the theory studies to practical phase, especially in the prevention and deal with natural disasters have obvious advantages. Taking the Er Yuan County Fengyu and Liantie triggered huge landslides due to heavy rain debris flow of Geological Disaster rescue as an example, this paper introduces in detail the application of the Unmanned Aerial Vehicle low-altitude photogram metric system. At beginning, there has a simply describes for the core function, advantages and the technical features of this Unmanned Aerial Vehicle low-altitude photogram metric system in the paper. Then introduces the important role played by the UAV aerial Photographic system in the geological survey and monitoring of disaster response.
