Abstract
A method for reconstructing three-dimensional faces is provided. The method includes: estimating a dynamic reconstruction parameter of a current video frame for three-dimensional face reconstruction by inputting, in response to a steady-state reconstruction parameter of the current video frame for the three-dimensional face reconstruction having been estimated by a pre-constructed teacher network model, the current video frame into a student network model distilled from the teacher network model; and reconstructing a three-dimensional face corresponding to the current video frame by inputting the steady-state reconstruction parameter and the dynamic reconstruction parameter into a pre-constructed three-dimensional deformation model.
