The invention discloses a picture duplicate checking method, a database, a device, a readable storage medium and a system, and the picture duplicate checking method based on Python comprises the steps: 1) obtaining a plurality of to-be-checked duplicate pictures and existing color pictures; (2) the color picture is zoomed by using a residual function; a 32 * 32 pixel RGB (Red, Green, Blue) three-channel image is obtained through zooming; and 3) performing DCT operation on the images according to the images of the RGB channels, and then combining the images to obtain an image 32 * 32 three-dimensional matrix and the like. According to the method, the sampling method is obtained through innovative experiments of the inventor, matrixes with more information of respective channels are found through induction, so that the hash value with more authenticity is obtained, the effect of complete and accurate checking of repeated pictures is better, and the efficiency is higher. 本发明公开一种图片查重方法、数据库、装置、可读存储介质及系统，一种基于Python
