Research On 3D Emotional Face Animation Based on Dirichlet Free Deformation Algorithm

Abstract

In the process of people's daily communication, the human face has played a decisive role, it includes joy, anger, sadness, music and other complex expressions, and also bear the function of language expression. Therefore, the construction of three-dimensional facial expression animation model and synthesis technology in computer graphics is one of the hot spots. How do you create realistic facial expressions and actions on virtual 3D people? This paper introduces the 3D facial expression animation system based on the Dirichlet free deformation algorithm. The system consists of two parts: the first part, using the Natural Point facial expression capture system to collect facial expression data; the second part, the use of Autodesk Maya animation software to establish the corresponding Face 3D model, and then use the Dirichlet free deformation algorithm as a deformation technique. Experimental results show that the system can be very good and real-time simulation of human (hi, anger, sad, music, etc.) complex expression. This study is of great help to human-computer interaction systems.
