Title:
ACCELERATION INFORMATION-BASED FOOT STEP COUNTING METHOD AND APPARATUS, AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/036926
Kind Code:
A1
Abstract:
Disclosed in the embodiments of the present application are an acceleration information-based foot step counting method and apparatus, and a device, the method comprising the following steps: acquiring original signals within a set time interval, and performing a synthesized acceleration processing on the original signals to obtain a synthesized acceleration signal; synthesizing n data points of the synthesized acceleration signal into one data segment, extracting feature points of the data segment, converting the feature points of all the data segments into feature point signals, analyzing the feature point signals to obtain a steady stage and a fluctuating stage of the feature point signals, performing periodic interference elimination, according to a set motion rule, on the feature point signals in the steady stage and the fluctuating stage to obtain interference eliminated feature point signals; and counting the number of peaks of the feature point signals after interference processing, the number of the peaks representing the number of steps. The present application has the advantage of realizing foot step counting.
