  Abstract: A novel posture similarity calculation method using selfadaptive joint weight was proposed in this paper.Kinect was selected to collect posture information,using which the human skeleton joint data was acquired.In order to accommodate various body shapes,the data of joints was modified according to the length of skeletons.In addition,the definition of selfadaptive joint weight was proposed in terms of various human postures.The experimental results showed that the proposed posture similarity calculation method achieved high accuracy and stable results.

  本文提出了一种新的自适应关节点权值的姿势相似度计算方法,该方法以模板姿势关节点为基础,对待测试姿势的关节点进行调整,有效解决了不同体型、位置之间的姿势预处理问题.以模板姿势的骨架长度为参考,给每个关节点增加一个权值,计算姿势相似度.实验结果表明:所提出的姿势相似度计算方法效果较好.
