Abstract
A method of 3D morphing driven by facial tracking is provided. First, a 3D model is loaded. After that, facial feature control points and boundary control points are picked up respectively. A configure file “A.config” including the facial feature control points and boundary control points data that are picked up corresponding to the 3D avatar is saved. Facial tracking algorithm is started, and then “A.config” is loaded. After that, controlled morphing of a 3D avatar by facial tracking based on “A.config” is performed in real time by a deformation method having control points. Meanwhile, teeth and tongue tracking of the real-time face image, and scaling, translation and rotation of the real-time 3D avatar image is also provided. In addition, a control point reassignment and reconfiguration method, and a pupil movement detection method is also provided in the method of 3D morphing driven by facial tracking.
