Real-time interaction 3D animation method, device and system

The invention discloses a real-time interaction 3D animation method, device and system. The method comprises steps that A, a virtual 3D role is established and is introduced to a figure engine to generate a role model; B, the actual actor motion information is captured in real time through a video or wearable equipment, and association and control on the role model are carried out; and C, the role model is integrated to an animation scene, the light effect is configured to the animation scene to match with the role model, and animation scene control is carried out through a control panel of a client background. The device comprises modules corresponding to each step of the method. The system comprises a capture device used for capturing the actual actor body motion or facial expressions in real time; the figure engine used for generating and processing the 3D role model, carrying out operation of physical dynamics motions of the 3D role model, and converting the animation video to output to video propagation
