Abstract
This application provides a method and apparatus for generating a 3D deformable head model. The method includes: receiving a two-dimensional (2D) facial image; identifying a first set of key points in the 2D facial image based on an artificial intelligence (AI) model; mapping the first set of key points to a second set of key points located on multiple vertices of a mesh of the 3D head template model based on a set of user-provided key point annotations located on a 3D head template model; deforming the mesh of the 3D head template model by reducing the difference between the first set of key points and the second set of key points to obtain a deformed 3D head mesh model; and applying a hybrid shape method to the deformed 3D head mesh model to obtain a head model based on the 2D facial image.
