Infrared image correction method, device, equipment and medium

The invention provides an infrared image correction method and device, equipment and a medium. According to a preset initial correction coefficient group, correcting the first pixel value of each pixel point to obtain a first corrected pixel value and a local variance, and determining the non-uniformity degree of each pixel point; according to the second correction pixel value of each pixel point of the previous frame of image, determining an inter-frame pixel difference, and determining the degree of non-uniformity of each pixel point; for each pixel point, determining an adaptive learning rate according to an inter-frame pixel difference and a local variance; obtaining a first expected pixel value through mean filtering, and determining an error value between the corresponding first correction pixel value and the first expected pixel value; according to the method, a better target correction coefficient group is obtained according to the error value, the adaptive learning rate and the first pixel value, and
