Infrared image detail enhancement method and system

The invention provides an infrared image detail enhancement method and system, and relates to the technical field of image processing, and the method comprises the steps: collecting an infrared image of a target object; extracting a detail layer image of the infrared image through a guiding filtering algorithm; carrying out mean filtering and denoising on the basic layer image of the infrared image; median filtering denoising and Laplacian filtering sharpening are carried out on the detail layer image of the infrared image; fusing the basic layer image of the infrared image and the detail layer image of the infrared image according to the weight; and performing Gamma transformation on the fused image to obtain a target image. According to the invention, more detail information of the image can be mined, the image with rich details and high contrast is obtained, the problems of low contrast and fuzzy details of the infrared image are solved, the accuracy of infrared image detection is improved, online detectio
