Image defogging method and system, electronic equipment and storage medium

The invention relates to an image defogging method and system, electronic equipment and a storage medium. The method comprises the steps of obtaining a to-be-defogged original image; filtering the pixel value of the original image by adopting a pixel window function to obtain a mean value of the dark channel image; converting the original image into an HIS image; reconstructing the brightness of the HIS image in a table look-up mode according to the mean value to obtain a brightness reconstructed HIS image; sequentially carrying out brightness enhancement and brightness curve correction on theHIS image after brightness reconstruction to obtain a corrected HIS image; performing color saturation adjustment on the HIS image to obtain an adjusted HIS image; and according to the corrected HISimage and the adjusted HIS image, converting the corrected HIS image and the adjusted HIS image by adopting an image conversion model to generate an RGB image, and obtaining a defogged image. According to the processing defogg
