Method and device for counting steps based on filter bank

Abstract

The present application provides a method and device for counting steps based on a filter bank, which includes: after acquiring a plurality of first motion signals of the monitored user, respectively performing denoising processing on the plurality of first motion signals to obtain a plurality of second motion signals. Motion signal, and each second motion signal is processed based on the preset filter bank to obtain the characteristic signal corresponding to each second motion signal, and the target characteristic signal is obtained according to the characteristic signal corresponding to each second motion signal, according to The target feature signal counts the number of steps of the monitored user, and processes the second motion signal through each set of filter banks in the preset filter bank to obtain the feature signal after certain processing in different directions, and suppress the impact of noise on the feature influence of the signal. And a target feature signal is determined according to the feature signal corresponding to each second motion signal, so that the target feature signal for counting can be determined from multiple feature signals, so as to improve the step counting accuracy.

Description

A filter bank-based step counting method and device technical field [0001] The application belongs to the technical field of step counting, and in particular relates to a filter bank-based step counting method and device. Background technique Pedometer is a kind of product that monitors user's movement data, and by monitoring user's movement data, it can affect user's health condition. For example, the number of heartbeats can be obtained through the user's motion data, and the user's health can be assessed by the number of heartbeats. Current pedometers have limited accuracy, resulting in reduced step counting accuracy. SUMMARY OF THE INVENTION In view of this, the purpose of this application is to provide a kind of step counting method and device based on filter bank, for improving High step counting accuracy. On the one hand, the application provides a kind of step counting method based on filter bank, described method comprises: obtaining a plurality of fir...

[0002] A pedometer is a product that monitors the user's exercise data. It monitors the user's health by monitoring the user's exercise data. For example, the heartbeat frequency can be obtained through the user's exercise data, and the user's health condition can be evaluated by the heartbeat frequency. However, the current pedometer The accuracy of the device is limited, resulting in a decrease in step counting accuracy
