基于北斗链路的无人机在地质灾害监测中的应用

Application of Beidou Link-Based UAV in Geological Disaster Monitoring

无人机作为在地质灾害监测中的重要工具,可提供实时的数据采集服务。本文以无人机为研究对象,提出了一种基于北斗系统的无人机通信方法,同时,结合机载激光雷达技术,提出一种实时点云的技术方案,使无人机能够精准采集地灾场景中的地理三维数据等信息,同时利用北斗通信链路实现无人机广域管控及实时、远距离的数据传输。之后,结合具体地灾场景,本文提出了基于可见光影像和热红外影像的技术方案,为实际地灾监测提供了参考。

As an important tool in geological disaster monitoring,UAV can provide real-time data acquisition service.Taking UAV as the research object,this paper puts forward a BDS-based UAV communication method.And combined with airborne lidar technology,this paper puts forward a technical scheme of real-time point cloud,that enables UAV to accurately collect geographic 3D data and other information in geological disaster scene,and realize UAV wide-area control and real-time,long-distance data transmission based on BDS link sim-ultaneously.Then,combined with the specific scenario,this paper puts forward the technical scheme based on visible light image and thermal infrared image,which provides a reference for the actual geological disaster moni-toring.
