Abstract

The invention discloses a step-counting interference removal method and device. The method comprises the following steps: acquiring a sampling data segment obtained through an acceleration sensor in a sampling manner, and acquiring n extreme points in the sampling data segment, wherein the extreme points comprise peak points and trough points; judging whether a difference value between amplitudes of the maximum peak point and the minimum trough point in the a extreme points is less than a step-counting threshold or not, wherein a is less than n; if the difference value is greater than or equal to the step-counting threshold, judging whether a difference value between the maximum peak point amplitude and a gravity acceleration is less than a first threshold in the neighborhood of the ith peak point, if the difference value between the maximum peak point amplitude and the gravity acceleration is less than the first threshold, determining that the peak point in the neighborhood of the ith peak point is an interference point, removing the peak point and the trough point in the neighborhood of the ith peak point, and counting the rest of the peak points to obtain counted steps.

Description

technical field [0001] The invention relates to the field of wearables, in particular to a method and device for removing step counter interference. Background technique [0002] With the improvement of living standards, people pay more and more attention to health, so various sports also rise thereupon. Among them, walking and running are among the more popular sports, and proper walking and running can bring about physical and mental health. Therefore, many wearable devices are equipped with a pedometer that counts steps through an acceleration sensor. However, the existing pedometers are susceptible to various interferences, resulting in inaccurate step counting of the pedometers. Contents of the invention [0003] The technical problem to be solved by the embodiments of the present invention is to provide a step counter interference removal method and device, which can effectively remove the interference and improve the accuracy of the pedometer. [0004] The presen...
