中文摘要：

提出人体下肢向量的概念,通过分析人体运动指出下肢向量能保持运动的主要特征,由此提出基于下肢向量特征不变性的人体运动重定向方法,以此提高运动捕获数据的可重用性。该方法面向人体下肢的运动重定向,能够将运动数据从原始骨骼模型重定向到具有不同骨骼长度比例的目标骨骼模型,同时保持原始运动的主要特征。实验结果表明,该方法具有较好的运动重定向效果和较快的计算效率。

英文摘要：

This paper presented the concept of human lower limbs vector,which could retain the primary feature of motion.After that,it presented a method of human motion retargeting based on fixity of lower limbs vector feature to reuse the existing motion capture data better.This motion retargeting method oriented human lower limbs,which retargeted the motion data from original human skeleton model to target human skeleton model which had different bone length.The retargeted motion retained the primary feature of original motion.The results of experiment show that this method has good motion retargeting effect and high computing efficiency.
