无人直升机航空应急测绘系统设计与实现

Design and implementation of unmanned helicopter aviation emergency surveying and mapping system

无人直升机具有环境适应能力强、机动灵活、可定点悬停的优势,在应急测绘地理信息保障中具有广泛的应用前景。本文从无人机平台、任务传感器、数据处理软件的集成关系入手,提出了包含结构设计、电气设计、控制流设计的多载荷一体化的集成设计方案,以及涵盖航摄设计、视频数据处理、光学面阵影像处理的软件系统集成方案;采用该方案实现了Z-5无人直升机航空应急测绘系统,并在安徽明光进行了飞行试验。结果表明,该系统可以同时获取视频和光学影像,并进行实时处理,满足实时提供应急测绘地理信息保障的要求。

Unmanned helicopters have the advantages of strong environmental adaptability,flexibility,and fixed-point hovering,and have broad application prospects in emergency mapping geographic information security. This paper starts with the integration relationship between UAV platform,task sensor and data processing software,and proposes an integrated design scheme including multi-load integration of structural design,electrical design and control flow design,as well as covering aerial photography design,video data processing,Software system integration solution for optical area array image processing. The Z-5 unmanned helicopter aviation emergency mapping system is implemented by this scheme,and the flight test is carried out in Mingguang City,Anhui Province. The results show that the system can simultaneously acquire video and optical images by real-time processing to meet the realtime provision of emergency mapping geographic information support.
