The embodiment of the invention discloses an image processing method and device. A specific embodiment of the method comprises the steps of obtaining a two-dimensional garment image, wherein the two-dimensional garment image comprises a style identifier of a garment; selecting a three-dimensional garment model matched with the style identifier from a pre-established three-dimensional garment modelset, and the three-dimensional garment model comprising marked hash points; based on a pre-established coordinate mapping relationship between the two-dimensional garment image and the three-dimensional garment model and the hash points of the selected three-dimensional garment model, performing hash point labeling on the obtained two-dimensional garment image; and generating a three-dimensionalgarment image of the acquired two-dimensional garment image based on the selected three-dimensional garment model and the annotation result. According to the embodiment, the speed of generating the three-dimensional garment image is increased.
