摘　　要：研究了一种基于H-Anim标准的实时人体三维动画方法,首先对H-Anim中人体肢体层次结构进行研究和分析,给出了进行人体动画的坐标变换方法;其次,基于OpenNI对Kinect获取的数据进行重新处理,采用逆运动学计算非根关节旋转矩阵;最后给出了系统流程及具体实验方法,采用OpenGL由实时获取的关节旋转矩阵驱动虚拟人实现了人体动画。实验结果表明,该算法可以较精确地提取人体三维姿态,实时重构人体运动。An approach to animating 3D human motion based on H-Anim standard is proposed.First ly,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 a chieved by using OpenGL to retarget the real-time human pose to the virtual human model.The experi mental results show that the proposed approach can accurately extract the human pose,and reconstructs real time human body movement.
