基于时间扭曲图快速搜索的运动融合方法

文章提出了一种基于时间扭曲图快速搜索的运动融合方法,实现了不同角色之间的运动合成。首先在动态时间扭曲的基础上加以一定的规则约束,提高了搜索对齐帧的速度,构造出时间扭曲曲线,实现运动序列之间的时间配准;然后对对应姿态之间进行局部姿态融合,重构角色根关节运动轨迹,合成最终的融合运动序列。实验结果表明,该方法缩短了对齐的时间,生成的混合运动流畅、协调,且保持源运动序列的主要特征。

A method of motion blending based on quick searching through time warping curve

A method of motion blending based on quick searching through time warping curve is put forward,which achieves motion synthesizing of different characters.Firstly,some of the constraints are given to dynamic time warping in order to improve the speed of searching the similar frame,and a curve of time warping is structured and the time aligning of motion sequence is obtained.Secondly,the corresponding posture is blended in local coordinate.Finally,the motion trajectory of character’s root joint is reconstructed,and the final motion sequence is synthesized.Experimental results prove that the proposed method can reduce the time of aligning,and the blended motion generated is smooth and harmonious and holds main characteristics of the original motions.
