摘要 大部分步态研究者将注意力投入到臀部和膝盖关节的角度变化所形成的步态特征,脚的步态特征关注还较少。针对这个问题深入研究了脚的一些特征,提取了脚尖数据进行分析,并对脚尖的坐标进行变换得到时域、频域及其他信息,在中科院数据库NLPR上进行试验和研究,表明脚尖的数据可以较好的区分男女性,甚至是不同的个体。脚尖数据的表示包含了较多的属性信息,有利于步态识别的进一步研究。 Most researchers focus on the gait characteristics of hip and angle changing of knee joints,less attention on gait characteristics of foot.This paper study in-depth of the toe gait characteristics,extracting tiptoe data and analyzing it,and transforming the axis of tiptoe trajectory to get time domain、frequency domain、and other related information.Test in the NLPR gait database of China Academy of Science,we found that tiptoe trajectory can differentiate sexity better,even different individuals.The characteristics of tiptoe data show the personal specific information and other attributed information,it's benefit for us to study further.
