Software step counting method based on mobile phone acceleration and distance sensors

Abstract

The invention discloses a software step counting method based on mobile phone acceleration and distance sensors and belongs to the field of electronic application. The step counting method is fused with the data of the mobile phone accelerator and the distance sensor; the accelerator sensor is used for performing human tread characteristic analysis; the distance sensor is used for judging the position of a mobile phone. The core idea is that the triaxial acceleration data is pretreated, and then the pseudo wave crest is filtered through a peak threshold value and a time threshold value and the step counting is realized through the residual effective wave crest. According to the method, the distance sensor data is introduced for improving the problem of low accuracy of step counting of people by holding the mobile phone, and the peak threshold value and the time threshold value are introduced for promoting the anti-interference capacity of people in non-step counting scenes, such as taking a bus, and reducing the mistaken step counting. The software step counting method is free from a complex filtering manner, the counted step number is outputted in real time under the condition of guaranteeing the step counting precision and the power consumption of the step counting is reduced.

Description

technical field [0001] The invention relates to the technical field of electronic applications, in particular to a software step counting method. Background technique [0002] With the progress of society and the improvement of people's living standards, more and more people spend time in sports. Especially walking and running sports, because they do not require sports equipment and specific sports scenes, have become a kind of sports craze rising in recent years, which has improved people's physical fitness. [0003] Since the development of smart phones, their functions have become more and more abundant, and they have become an indispensable part of people's lives. The user turns on the step counting function of the mobile phone anytime and anywhere, and monitors the amount of exercise in real-time walking, running and other scenarios in the form of total steps. With the continuous growth of usage, users have higher and higher requirements for the accuracy (accuracy) of...
