Three-dimensional face model generation method and apparatus, device, and medium

A three-dimensional face model generation apparatus, the apparatus comprising:

• a memory storing computer program instructions;
• and a processor coupled to the memory and configured to execute the computer program instructions and perform:
• obtaining a three-dimensional face mesh of a target object;
• aligning the three-dimensional face mesh with a first three-dimensional face model of a standard object according to face keypoints;
• and
• performing fitting on the three-dimensional face mesh and a local area of the first three-dimensional face model, to obtain a second three-dimensional face model after local fitting;
• and
• performing fitting on the three-dimensional face mesh and a global area of the second three-dimensional face model, to obtain a three-dimensional face model of the target object after global fitting.

A non-transitory computer-readable storage medium storing computer program instructions executable by at least one processor to perform:

• obtaining a three-dimensional face mesh of a target object;
• aligning the three-dimensional face mesh with a first three-dimensional face model of a standard object according to face keypoints;
• performing fitting on the three-dimensional face mesh and a local area of the first three-dimensional face model, to obtain a second three-dimensional face model after local fitting;
• and
• performing fitting on the three-dimensional face mesh and a global area of the second three-dimensional face model, to obtain a three-dimensional face model of the target object after global fitting.
