Image data optimization enhancement method

The invention relates to the technical field of image processing, in particular to an image data optimization and enhancement method, which comprises the following steps: acquiring a first image, preprocessing to obtain a second image, converting the second image into a third image to obtain a first brightness value, and enhancing the third image to obtain a second brightness value, converting the second image into a fourth image, performing neighborhood gray calculation to obtain a neighborhood gray ratio, performing corner detection processing on the fourth image to obtain a plurality of corners, performing neighborhood corner information calculation to obtain neighborhood corner information richness, and performing corner richness calculation based on the neighborhood corner information richness to obtain a corner richness ratio; and a contrast enhancement coefficient is calculated based on the neighborhood gray ratio and the angular point richness ratio, and a fifth image subjected to contrast enhancement
