Method and apparatus for processing waveform signal

Abstract

Disclosed are a method and apparatus for processing a waveform signal. The method comprises: acquiring a waveform signal after filtering; marking the waveform signal as K signal line segments according to the monotonicity; extracting line segment data of each of the signal line segments, and determining, according to the line segment data of each of the signal line segments, a line segment matching template of the waveform signal, wherein the line segment matching template comprises M consecutive signal line segments; and M is an integer less than K; matching each signal line segment in the Ksignal line segments with the M signal line segments comprised in the line segment matching template, and determining, according to a matching result of each signal line segment, a target wave group of the waveform signal; and determining, according to line segment data of the target wave group, periodic signal data of the waveform signal. The embodiments of the present application have the advantages of being capable of recognising periodic signal data of a waveform signal, improving the periodic recognition precision of the waveform signal and extracting relevant feature points.

Description

technical field [0001] The present application relates to the field of signal processing, in particular to a method and device for waveform signal processing. Background technique [0002] At present, with the increasing popularity of wearable devices, the implementation of sensors in the wearable devices to detect the user's ECG signals, blood flow signals, motion signals and other physical signs is also emerging. The ECG signal, photoelectric pulse wave signal or motion signal detected by the sensor on the wearable device is usually a waveform signal with characteristics of periodicity and continuity, so the user's physical health can be perceived by monitoring the waveform signal , you can find functions such as step counting cycle. [0003] However, the waveform signal detected by the sensor of the wearable device is easily affected by factors such as the way the wearable device is worn or the behavior of the user. The waveform signal contains large noise, which makes t...
