Yarn draft coloring method and device and electronic equipment

The embodiment of the invention provides a draft coloring method and device and electronic equipment, and relates to the technical field of image processing. The method comprises the following steps: acquiring a target shadow line corresponding to a to-be-colored line draft; the target shadow line is a line used for representing a shadow area corresponding to the line draft to be colored; determining target picture semantic information of the to-be-colored line draft by utilizing the to-be-colored line draft and the target shadow line; wherein the target picture semantic information is used for representing image characteristics of the line draft to be colored; and coloring the to-be-colored line draft based on the target shadow line and the target picture semantic information to obtain a target formed picture. Compared with the prior art, by applying the scheme provided by the embodiment of the invention, the shadow effect of the formed graph after the to-be-colored line draft is colored is improved, namely
