摘要
介绍了基于加速度传感器的便携式步态数据采集模块的设计方案。重点分析了步态加速度信号的特征,以及利用步态加速度的无偏自相关特性提取步态参数方法,并通过分析、对比人单步(左、右脚步)与步态周期间的相关系数,实现了步态对称性的评估。
This paper introduces a portable system which is used to measure gait cycle parameters and analysis gait symmetry. A three-axis accelerometer （MMA7260） is used to capture the acceleration signal of gait, and gait parameters could be calculated by an autocorrelation procedure. By analysis the ratio of correlation coefficient between signal step and gait cycle, gait symmetry could be estimated.
