In order to eliminate the non-uniformity of infrared images on uncooled infrared focal plane array and the blind elements generated in the imaging process, the image contrast and the real-time processing ability of infrared images are improved. In this paper, an electronic experimental platform based on the 120×90 infrared focal plane detector produced by Wuhan Guide Infrared company is built. Using the parallel processing and pipeline operation capabilities of field-programmable gate array (FPGA), two-point correction in non-uniformity correction, blind element compensation based on median filter, histogram equalization and false color transformation are realized on FPGA. The experimental results show that under the condition of 200 MHz input clock, this infrared image real-time processing module takes 604 s to process a frame of image, and has strong real-time performance. The research has practical significance for the application optimization of uncooled infrared focal plane arrays.
