摘　　要：跨介质空间高速飞行器在高速飞行时,电耦合器件(charge coupled device,CCD)相机的拍照往往由控制设备对其进行控制,其控制内容包括拍照控制、曝光时间控制等。文中研究了一种基于FPGA的自适应控制方法,能够取代控制器如CPU、单片机、ARM等器件,通过FPGA实时的对CCD相机进行拍照控制。同时能够根据图像的曝光情况,自适应的调整曝光时间,解决了飞行器搭载的CCD相机不能自动调整曝光的问题。满足了在复杂光照条件下CCD相机能够拍摄出较高质量图像的要求。During the high-speed flight of the transmedia space vehicle,the CCD camera is often controlled by the control equipment,which includes the control of photo-taking and exposure time.In this paper,an adaptive control method based on FPGA is studied,which can replace the controller such as CPU,MCU,ARM and so on.At the same time,the exposure time can be adjusted adaptively according to the exposure condition of the image,which solves the problem that the CCD camera on the aircraft can not adjust the exposure automatically.It can meet the requirement of high quality image taken by CCD camera under the condition of complicated.
