Abstract

Abstract

In order to improve the image quality of certain medium wave infrared detector, a infrared image real-time processing system based on FPGA is designed, which can accomplish nonuniformity correction and blind pixel compensation in real time. Some widely used nonuniformity correction algorithms, blind pixel detection and compensation algorithms are introduced. Combined with actual project requirements, nonuniformity correction with multi-point method and blind pixel compensation with eight-point average method are realized on the FPGA platform on the basis of successful simulation. User-defined coefficient updating, non-correction coefficients manually or automatically calculating and blind pixel lists automatically updating are realized by the system. The processing system is tested using certain domestic medium wave infrared detector, and the result shows that the nonuniformity of corrected image is less than 0.3% and the blind pixel of corrected image is less than 0.001%. The system is stable and reliable, which satisfies the requirements of image processing in real-time and accurancy.
