| 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. |
