AI Technical Summary

Problems solved by technology

Currently, both ECG and PPG require the subject to wear different sensors, which can be uncomfortable for the patient, and even more inappropriate for patients with damaged skin
In addition, ECG generally requires an instrument to assist analysis, which reduces the scope of use of ECG and is not easy to carry.

Abstract

The invention discloses a portable Raspberry Pi-based remote heart rate detection device and method. The method comprises the following steps: step 1, acquiring a facial image of a subject in real time; step 2, face feature point detection and ROI positioning and tracking are carried out; 3, calculating an original signal; step 4, variational mode decomposition is carried out on the extracted original signal; 5, extracting a heart rate component and calculating average heart rate data; and step 6, displaying the image after face processing and the heart rate data in real time. The problem that a subject needs to be in direct contact with detection equipment in current heart rate detection is solved, accurate and automatic heart rate detection is achieved, the comfort of the subject can be greatly improved, direct contact with a person to be detected is avoided, and heart rate monitoring of the subject in a comfortable state is facilitated. The system has higher popularization and use values in daily heart rate monitoring, and has the characteristics of simple structure, convenience in carrying, easiness in debugging, high detection accuracy and the like.

Description

technical field [0001] The invention relates to the technical field of medical detection, in particular to a portable remote heart rate detection device and method based on Raspberry Pi. Background technique [0002] The heart is the most important organ of human beings. The detection of heart rate, heart rate variability, atrial fibrillation and other physiological parameters that directly reflect the function of the heart is of great significance to understanding the physiological health status of individuals. Currently, heart rate measurement techniques are mainly classified into electrocardiogram (ECG for short) and plethysmography (Photoplethysmography, PPG for short). ECG requires the subject to wear sensors on different parts of the body, and the sensor captures the myocardial current generated by the heart's work, so as to extract the heart rate information. The PPG uses the principle of optics to evaluate the heart rate by measuring the periodic changes in the inte...
