Abstract

The present invention provides a method for automatically generating a super-realistic 3D face model based on machine learning, comprising the following steps: S1, using a 3DMM three-dimensional deformation model to fit a 2D face picture into a 3D face model; S2, using a deep learning neural network to generate UV map; S3, applying the UV map to the 3D face model to generate a super-realistic 3D face model; based on a 2D face picture, a super-realistic 3D face model can be generated without other equipment and steps, greatly The generation steps and costs are simplified.

Description

technical field [0001] The invention belongs to the technical field of computer vision, and in particular relates to a method for automatically generating a super-realistic 3D facial model based on machine learning. Background technique [0002] With the development of computer graphics technology, 3D face modeling and 3D face models with expressions and actions have become a research hotspot in the field of computer graphics. 3D face modeling and 3D face models with expressions and actions have been gradually promoted and applied to many fields such as virtual reality, film and television production, face recognition, game entertainment, etc., and have strong application value. [0003] The method that the three-dimensional human face model generation with expression action is at present is: the static human face three-dimensional model (specifically with reference to CN106164979A) obtained by structured light three-dimensional imaging equipment, then utilizes animation pro...
