基于改进DTW的上肢康复运动评价

针对动态时间规整DTW算法应用于上肢康复运动评价时存在的起点和终点难以对齐的问题,文章通过引入速度特征对常规的DTW进行改进,基于Kinect传感器实现康复运动数据和标准运动数据的自动对齐。实验结果表明,该系统能够实现自动截取有效的运动序列数据,从而使得匹配结果更加准确。

In order to solve the matching alignment of upper limb rehabilitation movement based on DTW algorithm,a novel modified DTW method based on speed character is proposed,which can automatic realize alignment for upper limb rehabilitation movement by using Kinect.According to trail result,this method can automatic filter the raw movement sequence data,leading to more accurate matching.
