Image comparison method and device

Abstract

The invention discloses an image comparison method and device, a medium and equipment, and the method comprises the steps: obtaining a to-be-detected image and a standard image, and enabling pixels in the to-be-detected image to be in one-to-one correspondence with pixels in the standard image; calculating a pixel difference value between the pixel point in the to-be-detected image and the pixel point in the corresponding standard image, judging whether the pixel difference value is greater than a preset difference value threshold value or not, and taking the pixel point in the to-be-detected image as an error pixel point when a judgment result is yes; counting the number of the error pixel points, and judging whether the to-be-detected image meets the visual requirement or not according to the number of the error pixel points. From the perspective of visual verification, the image comparison result can better meet the visual verification requirement.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to an image comparison method, a computer-readable storage medium, a computer device and an image comparison device. Background technique [0002] In the related art, when comparing two images, the method of feature quantity comparison is often used to judge whether the two images are consistent through the comparison of feature quantities; The similarity between images, in the process of visual verification, the results obtained by this method are often inaccurate (that is, the feature quantity judgment results are consistent, but the difference between the two images can be clearly observed by the naked eye). Contents of the invention [0003] The present invention aims to solve one of the technical problems in the above-mentioned technologies at least to a certain extent. Therefore, an object of the present invention is to provide an image comparison method, w...
