Image processing method and device

An apparatus for processing an image, the apparatus comprising:

• at least one processor;
• and
• a memory storing instructions, the instructions when executed by the at least one processor, causing the at least one processor to perform operations, the operations comprising:
• acquiring a two-dimensional garment image, wherein the two-dimensional garment image includes a style identifier of a garment;
• selecting a three-dimensional garment model matching the style identifier from a pre-established set of three-dimensional garment models, wherein the three-dimensional garment model includes scatter points labeled thereon;
• labeling the two-dimensional garment image with scatter points based on a pre-established coordinate mapping relationship between the two-dimensional garment image and the three-dimensional garment model and the scatter points of the selected three-dimensional garment model;
• performing coordinate transformation on the scatter points of the acquired two-dimensional garment image, and determining coordinate information of the scatter points after the coordinate transformation;
• generating a primitive having a preset shape based on the coordinate information of the scatter points after the coordinate transformation, the primitive comprising a preset number of scatter points after the coordinate transformation and a connection relationship between the scatter points;
• rasterizing the primitive to obtain a fragment set of the primitive, wherein a fragment in the fragment set includes a color value and texture coordinate information;
• and
• performing texture coordinate mapping on the fragment set to obtain pixels of the selected three-dimensional garment model;
• generating the three-dimensional garment image based on the obtained pixels.

A non-transitory computer readable storage medium, storing a computer program thereon, wherein the program, when executed by a processor, implements operations, the operations comprise:

• acquiring a two-dimensional garment image, wherein the two-dimensional garment image includes a style identifier of a garment;
• selecting a three-dimensional garment model matching the style identifier from a pre-established set of three-dimensional garment models, wherein the three-dimensional garment model includes scatter points labeled thereon;
• labeling the two-dimensional garment image with scatter points based on a pre-established coordinate mapping relationship between the two-dimensional garment image and the three-dimensional garment model and the scatter points of the selected three-dimensional garment model;
• performing coordinate transformation on the scatter points of the acquired two-dimensional garment image, and determining coordinate information of the scatter points after the coordinate transformation;
• generating a primitive having a preset shape based on the coordinate information of the scatter points after the coordinate transformation, the primitive comprising a preset number of scatter points after the coordinate transformation and a connection relationship between the scatter points;
• rasterizing the primitive to obtain a fragment set of the primitive, wherein a fragment in the fragment set includes a color value and texture coordinate information;
• performing texture coordinate mapping on the fragment set to obtain pixels of the selected three-dimensional garment model;
• and
• generating the three-dimensional garment image based on the obtained pixels.
