摘　　要：针对传统嵌入式系统难以处理和显示高速大数据量的红外图像的问题,介绍了基于Xilinx公司集成了双核ARM和FPGA的全可编程Zynq SOC的高速红外成像系统,其FPGA实现探测器图像采集、非均匀校正、VDMA视频流传输等功能,ARM处理器运行Linux系统,完成通过USB Wi Fi或千兆以太网的网络视频传输。实验结果显示该系统能够实现高速率、高分辨率的红外成像,功耗低,结构简单,通用性强。The traditional embedded systems are difficult to handle and display high-speed infrared image with large amounts of data. To solve this problem,a high speed infrared imaging system based on all programmable Zynq SOC that integrates with dual core ARM and FPGA from Xilinx. The FPGA is adopted to implement image acquisition,non-uniform correction,VDMA video transmission,and other functions; ARM processor runs Linux system; video transmission is completed through USB Wi Fi or gigabit Ethernet network. Experimental results show that the system can achieve a high-speed infrared imaging with high-resolution,and it has low power consumption,simple construction and strong commonality.
