Embodiment

[0062] Example: Heart rate measurement of different people.

[0063] 1. In order to further illustrate the accuracy of heart rate detection by this algorithm, it proves that heart rate detection can be performed equally for different people and people in different states. In this paper, the previous testers are named as tester 1, tester 2 and tester 3, and the heart rate detection results of tester 2, tester 3 and tester 1 after exercise will be listed below for comparative analysis.

[0064] 2. Comparing the RGB component waveforms of tester 1, tester 2, and tester 3, it can be clearly found that the RGB components of tester 1 and tester 2 have obvious similarities, and there are three obvious waveforms with large amplitudes. , and appear in similar positions. If it is reflected in the human body, the two people should have similarities in some aspects. Furthermore, observing the waveforms of the three, it can be roughly seen that the waveforms of the three have a certain p...

Abstract

The invention provides a human face video image based heart rate detection system which comprises a video recording module, a face recognition module, an RGB separation module, an independent component analysis module and a physiological parameter quantization module. The video recording module, the face recognition module, the RGB separation module, the independent component analysis module and the physiological parameter quantization module are connected successively. The heart rate detection methods include steps of video recording, face recognition, RGB separation, independent component analysis and decomposition, physiological parameters quantification. The system and the method have the advantages of high calculation efficiency, effectively overcoming the influence of human face contour, light and other environmental factors. The system can also remind real-time cardiovascular changes, solve the problem of inaccurate measuring results due to the discomfort of a patient to contact detection, and has a large application prospect in remote medical care.

Description

technical field [0001] The invention belongs to the technical fields of portable medical treatment and Internet medical treatment, and relates to a method for detecting heart rate by collecting human face video images through a camera. Background technique [0002] Routine and non-invasive testing of cardiovascular function is an important method for preventing cardiovascular diseases and treating chronic diseases. At the same time, resting heart rate is one of the most basic and important parameters for detecting cardiovascular diseases, and a high resting heart rate is considered to be one of the important factors causing cardiovascular diseases. At present, heart rate detection is mainly divided into clinical and commercial detection. Clinically, the standard methods of heart rate detection technology (such as electrocardiogram, ECG) generally require patients to wear gel patches or chest straps, which will not only cause discomfort to patients but also may affect the de...
