Abstract
An animation system integrating face and body tracking for puppet and avatar animation by using a 3D camera is provided. The 3D camera human body and facial animation system includes a 3D camera having an image sensor and a depth sensor with same fixed focal length and image resolution, equal FOV and aligned image center. The system software of the animation system provides on-line tracking and off-line learning functions. An algorithm of object detection for the on-line tracking function includes detecting and assessing a distance of an object; depending upon the distance of the object, the object can be identified as a face, body, or face/hand so as to perform face tracking, body detection, or ‘face and hand gesture’ detection procedures. The animation system can also have zoom lens which includes an image sensor with an adjustable focal length f′ and a depth sensor with a fixed focal length f.
