The invention relates to a dead pixel processing method and device based on an infrared image, and belongs to the technical field of image processing, and the method comprises the steps: carrying out the dead pixel recognition of the infrared image; selecting pixel points which are located on the same straight line with the dead pixel as initial pixel points, wherein the number of the straight lines is at least two; selecting associated pixel points according to the distance between each initial pixel point and the dead pixel; obtaining a corrected pixel value of the dead pixel according to the associated pixel point; and replacing the original pixel value of the dead pixel with the corrected pixel value. The problem that the visual effect of the infrared image is very poor due to the fact that the quality of the infrared image is seriously influenced by the existence of the dead pixels is solved, and the method has the effects of correcting the dead pixels and improving the quality of the infrared image. 本申请
