Mixing uniformity evaluation method based on high-speed mixer

The invention relates to the technical field of high-speed mixers, in particular to a mixing uniformity degree evaluation method based on a high-speed mixer, and the method comprises the steps: obtaining a gray image of a mixing surface image; obtaining the content ratio of each raw material in the mixed material according to the contents of different raw materials so as to calculate the theoretical information entropy of the mixed material, obtaining the size of a tile window according to the content ratio, calculating the information entropy of a gray structure in each tile window, and obtaining the gray texture uniformity of the gray image in combination with the theoretical information entropy; segmenting the grayscale image into a plurality of superpixels based on the grayscale value corresponding to each raw material, and obtaining the superpixel distribution uniformity degree of each raw material according to the Euclidean distance of the centroid between the superpixels, thereby obtaining the comprehe
