主被动多传感器组合的宽角成像系统设计与实验

Design and Experiment of An Active-Passive Multi-sensor Combined Wide-Angle Imaging System

  • 摘要: 按照国家航空应急测绘的需求提出了一种多传感器组合成像系统。在此系统中,将组合数码相机、视频和红外相机、激光雷达(light detection and ranging,LiDAR)和小型合成孔径雷达(miniature synthetic aperture radar,MiniSAR)集成到统一的时空基准,分别且同时地实现大像幅光学成像,白天和夜间视频影像获取与传输,三维激光点云获取,以及全天候的微波遥感。详细阐述了组合宽角相机在改善影像质量和作业效率方面的优势。根据上述设计,将实验系统安装在中航时无人机上进行了飞行检验,给出了所获取的白天和夜间数据成果。

     

    Abstract: A multi-sensor combined imaging system is proposed based on the aerial survey requirements for national level emergencies. This system integrates digital cameras, video and infrared cameras, LiDAR and MiniSAR into a unified benchmark of space and time. It can perform optical large format imaging, daytime and night video imaging for real time transfer, 3D laser point clouds acquisition, and all-weather microwave sensing respectively and simultaneously on a flying platform. The advantages of combined wide-angle cameras for improving image quality and operation efficiency are described in detail. Based on this design, an experimental system was installed in a medium duration UAV, to make test flights. Observed daytime and night data are shown.
