Problems solved by technology

However, due to factors such as external vibration interference, constant changes in the position of the human body, and the noise of the sensor itself, the collected data often contains a lot of noise, and the pressure change caused by the heartbeat is very weak, which brings difficulties to the accurate identification of the heart rate. difficulty

Abstract

The embodiment of the invention provides a contactless heart rate testing method and related equipment. The method and the related equipment are used for greatly improving the accuracy and reliabilityof recognition of a heart rate. The method includes the steps of collecting heart rate data of a person whose heart rate is about to be tested through a preset sensor; determining a heart rate prediction convolutional neural network CNN model; inputting the heart rate data into the heart rate prediction CNN model to output a periodic curve; converting the periodic curve to a target heart rate through Fourier transform, wherein the target heart rate is the heart rate of the person whose heart rate is about to be tested.

Description

technical field [0001] The present application relates to the field of medicine, in particular to a non-contact heart rate testing method and related equipment. Background technique [0002] Heart rate (heart rate) is of great significance to measure the health of a person's heart. It refers to the number of heart beats per unit time and is a physiological parameter for routine clinical diagnosis. Heart rate changes are closely related to heart disease, so it is very important to know your heart rate status in time. [0003] Most of the existing heart rate measurement is to place highly sensitive pressure sensors on mattresses or pillows to collect pressure changes caused by body movements, breathing, and heartbeat, and then filter the collected data in different frequency bands, and obtain them through frequency analysis. heart rate. Some methods collect pulse signals generated by the human body by placing piezoelectric cables on the mattress, select half of the average v...
