3d Tracking Of The Movement Of Manpower Study

Research on 3D hand tracking is the fundamental and key project which covers various cross-disciplines, such as computer image and graphics, Human Computer Interaction(HCI), computer vision, projective geometry, estimation methodology, software computation theories. So, it is most significant to conduct thorough research on three dimension(3D) hand tracking for boosting theories and applications of intelligent HCI in VR and promoting the application and research of relative disciplines.Appearance-based tracking and model-based tracking are fundamental methods to track human motion hands, and this paper mainly studies model-based tracking way to track 3D hands, aiming at obtaining continuously 3D hand gestures and their positions corresponding to the frame images for the harmonious and natural and convenient HCI. Under the circumstance of multi-views, the 3D hand gestures can be obtained according to the corresponding feature points, and under the circumstance of single-view, the 3D hand gestures at time k can be obtained by prediction and filtering according to the 3D hand gestures at time k-1 and the frame images at time k.Because a hand gesture, on itself, is characterized by multiformity in appearance, ambiguousness in semanticness and differences in space-time, vision-based tracking and recognition to the human hand is a challenging project. Besides, a hand gesture is characteriatic of high degree of free(DOF), small phalanges, self-occlusion and ill-posed problems, so 3D hand tracking is complicated and formidable. This project is motivated by, and fused into the Research on Some Key Techniques and Its Typical Applications of A Virtual Prototyping(2002AA411310).The paper researches on some of the key problems in 3D hand tracking.There are many key problems in 3D hand tracking.Under the circumstance of single-view, Extended Kalman Filter(EKF) will lose the ability to tracking states when the states of the moving hand abruptly change; the existing ways to deal with hand...
