Face modelling is the key to modern visuals in special effects movies and computer games. In this paper, based on the dynamic modelling of 3D face model, a modelling method based on feature extraction is proposed. For the captured face image, firstly locate the face region, then extract the face feature points of the face region, and deform the standard 3D face model according to the extracted face feature points, and finally obtain a real-time three-dimensional image. Face animation system. The experimental results show that the proposed method can accurately complete the face modelling of the corresponding expression in real time for 3D face modelling, which has high real-time and accuracy.
