We propose an onboard image real-time processing system based on FPGA, it includes onboard image receiving and storage, image processing, data transmission, the control of CPU interface, and reliability design of the whole system. The system hardware platform consists of camera LVDS receiver chip, SDRAM buffer circuits, FPGA, CPU and satellite LVDS transmitter chip. The system has been verified in the actual satellite project such as target tracking and image compression. It has the characteristics of real-time processing, small resource occupation coefficient and high reliability.
