Design of infrared high-speed imaging system based on all programmable SOC

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 WiFi 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.
