无人机低空航摄技术在川东北山区滑坡调查中的应用

Application of UAV Low-altitude Aerial Photography Technology to Landslide Investigation in Northeast Sichuan

近年来,国内外山区滑坡地质灾害频发,传统调查手段受客观条件影响而作用有限。本文介绍了无人机低空航摄技术的基本原理,总结了利用无人机航摄技术进行山区滑坡灾害调查的基础流程,以川东北某石膏矿矿区为例开展了山区无人机航摄调查应用分析,结果表明无人机低空航摄技术在保障地灾调查精度的基础上极大地提高了工作效率,弥补了传统地面调查方法易"重局部、轻整体"的缺陷。

In recent years,landslides in domestic and foreign landslides are frequent. The traditional means of investigation are limited by objective conditions. The paper introduces the basic principle of UAV low altitude aerial photography technology,summarizes the basic process of using the UAV aerial technology to carry out the investigation of landslide hazard in mountainous area and takes a gypsum mining area in northeastern Sichuan as an example to carry out aerial survey of mountain unmanned aerial vehicles. The results show that UAV low altitude aerial technology can greatly improve the working efficiency and make up for the shortcomings of the traditional ground investigation method.
