Abstract The invention discloses an underwater vision slab optimization method and system based on image enhancement, and the method comprises the following steps: carrying out the RGB channel separation of an original underwater image, calculating the channel average value of each channel and the adaptive equalization factor of the corresponding channel, compensating each channel through employing the equalization factor, and carrying out the merging, and obtaining a color compensation image; an improved dark channel defogging algorithm and a big law threshold segmentation algorithm are adopted to process the color compensation image, an atmospheric light value A is obtained through the big law threshold segmentation algorithm, and then the transmittance is controlled through a dark channel normalized mean value and the atmospheric light value A to obtain a defogged image; smoothing the defogged image by using Gaussian filtering, and performing linear transformation on a difference image of the original image and the
