| Abstract: | According to the infrared image characteristics, the hardware of real-time image processing is designed based on FPGA and SRAM in order to improve the quality of infrared image. The hardware system indudes four function modules： video processing A/D module, FPGA module, image storage module and video processing D/ A module. The images collected by the non- refrigeration infrared imagingsystem can be converted into 8 bit digital signals through the A/T） module. FPGA is the key part which can realize image sharpening and smoothing. The arrays of SRAM are for store the real-time image for a while. At the last, D/A can recover the digital signals to analog ones. And the result can be performed on the video. |
