基于FPGA和DSP的抗单粒子高清图像采集处理系统设计

Design of Anti-SEE HD Image Acquisition System Based on FPGA and DSP

  • 摘要: 与传统的CCD相比, CMOS图像传感器因其相对简单的驱动, 更低的功耗, 更强的抗辐射能力, 在空间探测领域得到了越来越多的应用.采用CMOSIS公司生产的CMV4000的图像传感器, 基于FPGA和DSP设计完成了分辨率为2 048×2 048, 10frame/s的高清图像采集系统.从器件选型、逻辑设计等方面考虑了系统的抗单粒子效应设计.试验结果表明, 系统运行稳定可靠, 由单粒子翻转造成的功能中断小于10-2次/天, 安装光学系统后能够高质量成像.

     

    Abstract: Compared with traditional CCD, CMOS image sensor has been widely applied in space exploration because it needs no complex driver circuit, has low power features and high anti-radiation ability.CMV4000 image sensor of CMOSIS is chosen in this paper.An image acquisition system of 2 048×2 048 pixels based on FPGA+DSP is presented at the rate of 10-frame/s.The acquisition system is designed for anti-single event effect according to the type of device and the logic design.The experimental results show that the system is stably and reliability, the functional termination caused by the single event effect is less than 10-2 times per day, the high definition image can be generated after the optical system is completed.
