VR conference control system and method based on face modeling and expression tracking

The invention discloses a VR conference control system and method based on face modeling and expression tracking, and the system comprises a conference scene selection module, a face detection module,a feature point extraction module, a 3D face model generation module, a facial expression tracking module, and an interaction module, wherein the conference scene selection module is used for entering a conference scene according to the user's selection; the face detection module is used for recognizing face information of a wearer; the facial expression tracking module is used for obtaining a plurality of feature points in the face information every other preset time period and mapping the feature points into the 3D face model in real time, and the interaction module is used for outputting aconference scene and the 3D face model. According to the invention, the real-time change of each feature point in the face information can be accurately updated to the 3D face model in real time, i.e., the expression change o
