基于FPGA的星载图像实时处理系统设计

摘要

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.%提出了一种基于FPGA的星载图像实时处理系统，系统包括星载图像接收、SDRAM缓存、数据下传和CPU接口控制，并对整个系统做了可靠性设计。该系统硬件平台包括相机LVDS接收芯片、SDRAM缓存电路、FPGA、CPU和卫星LVDS发送芯片。该系统在目标跟踪和图像压缩等实际卫星项目中得到了验证，具有实时处理、占用资源小、可靠性高等特点。
