The present invention relates to a character design method, device and medium, including: S1: obtaining an image
data set constituting character accessories; S2: sorting out the image
data set; S3: constructing an accessory counter model; S4: obtaining a style number by means of a jump scanning method for the sorted image
data set; S5: inputting the style number into the accessory counter model to generate a
gene code; S6: combining the character name, product code and
gene code into a product ID code; S7: rendering the ID code and outputting the rendered picture; Step S4 specifically includes: S41: obtaining a scanning
base number, a theoretical total number and the number of accessories in the folder; S42: defining a starting number array; S43: creating a stride number array by means of the jump scanning method; S44: obtaining the style number through the scanning
base number, the starting number and the stride number. The present invention effectively solves the problems of low character design efficiency and inability to batch generate pictures, and provides a large number of
animation character solutions, randomly appearing character images and blind box pattern products.
