A method of visual modeling, characterized by, The method comprises: obtaining a template image, the template image comprising a printed icon; obtaining a carton type; determining position information of the printed icon according to the carton type; determining feature information corresponding to the position information based on the position information, the feature information being used to represent features of the printed icon; generating a visual model according to the position information and the feature information; wherein, when the obtained carton type is a printed carton, the determination of the position information of the printed icon according to the carton type comprises: binarizing the template image to obtain a binary image; determining first position information of the printed icon relative to the template image according to the binary image; when the obtained carton type is a die-cut carton, the determination of the position information of the printed icon according to the carton type comprises: determining a die-cut line corresponding to the template image according to the template image; determining an effective printing area corresponding to the die-cut line according to the die-cut line; determining second position information of the printed icon relative to the effective printing area according to the effective printing area; when the obtained carton type is a fitted carton, the determination of the position information of the printed icon according to the carton type comprises: determining a die-cut line corresponding to the template image according to the template image; determining an effective printing area corresponding to the die-cut line according to the die-cut line; determining a folding line corresponding to the template image according to the template image; cutting the effective printing area into a plurality of cut images according to the folding line; determining a folding direction corresponding to the folding line according to the folding line, and determining a positional relationship between the cut images according to the folding direction and the cut images; splicing the cut images based on the positional relationship to obtain a fitted carton image; determining third position information of the printed icon relative to the fitted carton image according to the fitted carton image.

2. The method of claim 1, wherein, The determination of the die-cut line corresponding to the template image according to the template image comprises: obtaining line information in the template image, the line information at least comprising the die-cut line; extracting the die-cut line corresponding to a first color from the line information based on the first color corresponding to the die-cut line.

3. The method of claim 1, wherein, The determination of the folding line corresponding to the template image according to the template image comprises: obtaining line information in the template image, the line information at least comprising the folding line; extracting the folding line corresponding to a second color from the line information based on the second color corresponding to the folding line, wherein the second color is different from the first color.

4. The method of claim 1, wherein, The determination of the feature information corresponding to the position information based on the position information comprises: determining a feature extraction mode corresponding to the position information based on the position information and the printed icon; extracting feature information corresponding to the printed icon according to the feature extraction mode; the feature extraction mode at least comprises: a first feature extraction mode for extracting line features; and a second feature extraction mode for extracting texture features.

5. A visual modeling device, characterized by, The device comprises: an obtaining module configured to obtain a template image, the template image comprising a printed icon; the obtaining module is further configured to obtain a carton type; determining a position information of the printed icon according to the carton type; the determining module is further configured to determine feature information corresponding to the position information based on the position information, the feature information being used to represent a feature of the printed icon; generating a visual model according to the position information and the feature information; when the obtained carton type is a printed carton, the determining module is configured to binarize the template image to obtain a binarized image, and determine first position information of the printed icon relative to the template image according to the binarized image; when the obtained carton type is a die-cut carton, the determining module is configured to determine a die-cut line corresponding to the template image according to the template image, determine an effective printing area corresponding to the die-cut line according to the die-cut line, and determine second position information of the printed icon relative to the effective printing area according to the effective printing area; when the obtained carton type is a laminated carton, the determining module is configured to determine a die-cut line corresponding to the template image according to the template image, determine an effective printing area corresponding to the die-cut line according to the die-cut line, determine a folding line corresponding to the template image according to the template image, cut the effective printing area into a plurality of cut images according to the folding line, determine a folding direction corresponding to the folding line according to the folding line, determine a positional relationship between the cut images according to the folding direction and the cut images, splice the cut images based on the positional relationship to obtain a laminated carton image, and determine third position information of the printed icon relative to the laminated carton image according to the laminated carton image.

6. An electronic device, comprising: comprise: at least one processor; and a memory connected with the at least one processor in communication; wherein the memory stores instructions executable by the at least one processor, and the instructions are executed by the at least one processor to enable the at least one processor to perform the method of any one of claims 1-4.

7. A non-transitory computer-readable storage medium having stored thereon computer instructions, wherein, The computer instructions are used to enable the computer to perform the method of any one of claims 1-4.
