Abstract:

An approach to animating 3D human motion based on HAnim standard is proposed. Firstly, the human body hierarchical structure in HAnim is studied and analyzed, and a coordinate transform strategy is given based on the analysis. Secondly, based on OpenNI, the data received from the Kinect is reprocessed, and the rotational matrix of nonroot joint is obtained by inverse kinematics. Finally, the entire data flow and the concrete implementation are described, and the human body animation is achieved by using OpenGL to retarget the realtime human pose to the virtual human model. The experimental results show that the proposed approach can accurately extract the human pose, and reconstructs realtime human body movement.
