摘要
Abstract
A new area peak step detection algorithm was presented to decrease the interference of wrist swing to the step detection in the human motion. It was based on the characteristics of the acceleration signal of human motion,us⁃ing Gaussian filter to cut down the noise effect on acceleration signal,and applying area peak detection to determine the effective step on the basis of the data of triaxial resultant acceleration. Besides,the variation of the amplitude of the acceleration signal was used as the eigenvalue,making realization of the automatic recognition of steady-state walk and run as well as the automatic adjustment of the sampling rate on various motional state,effectively reducing power dissipation. The experimental results show that,compared with dynamic threshold algorithm and single peak algorithm,the area peak step detection algorithm has highly precision in step detection,up to more than 95%.关键词
