Abstract: This paper proposes a motion fusion method without manual intervention, suggests a way to identify the motion cycle based on joint movement. The cycle is calculated through the analysis of the motion capture data and the angle between the knees and the hips node. Then high-quality motion blending animation comes into being after the steps of time and space warping, interpolation, and constraints reconstruction. The result shows that the proposed algorithm can calculate the motion cycle accurately and make the fusion motion under constraints more realistic.

摘要： 介绍了一种不需要人工干预的运动融合方法，提出了基于关节运动规律的运动周期判别方法。通过分析运动捕获数据，计算双膝与臀部节点连线夹角的变化来确定运动周期，然后再进行时空变形、插值与约束重建，从而生成高质量的运动融合动画。实验结果表明本算法能够准确的计算出运动周期，并且使约束后的融合动作更加真实。
