摘　　要：提出一种基于关键姿态映射的运动重定向方法,实现不同角色之间运动序列的快速映射。首先,对源运动数据降维,在低维空间中做聚类分析,提取关键姿态;其次,参数化运动序列,计算运动权值;最后,自动求解目标角色的关键姿态,结合运动权值重构目标角色的运动。实验结果表明,该方法较为完整的保留了源运动序列的特征,且重定向得到的运动较为平滑自然。An approach to motion retargeting based on key-postures mapping was proposed, which achieved fast motion retargeting between different characters. Firstly, the original high-dimensional motion data was mapped into a low-dimensional space, and the key-postures were extracted. Secondly, the original motion sequence was parameterized and the weights were computed. Finally, the key-postures of the target character were solved automatically, and motion of the target character was synthesized by these weights of the original motion. Experimental results demonstrate the method can hold main feature of source character. Moreover, the retargeted motion is quite smooth and natural.
