摘　　要：针对目前基于图像拼接法和鱼眼镜头法无人机载全景成像实时性低、成本高的问题,设计了一种微型无人机载实时全景成像设备。采用基于抛物面反射镜的折反射全景成像方式,通过无线通信实时获取机载全景图像视频,并利用投影变换展开成柱面全景图像,从而实时获得水平方向360°、垂直方向286°范围内的大视场图像,提高了无人机载大视场成像的实时性,降低了系统成本,为进一步释读图像奠定了重要基础。The panoramic imaging onboard UAV based on image mosaics or fish eye lenses has the shortages of low real-time performance or high cost. To solve the problems, we designed a UAV real-time panoramic imaging equipment. The catadioptric panoramic imaging based on parabolic reflector was used, and real-time airborne panoramic image was obtained through wireless communication, which was then changed to cylindrical panoramic image through projection transformation. Thus a real-time, large field-of- view image（360° in horizontal and 286° in vertical）was obtained. The method can improve the real-time performance large FOV imaging and decrease the cost, which lays an important foundation for further image interpretation.
