Embodiment Construction

[0025] The specific embodiment of the present invention is described below:

[0026] In this embodiment, the implementation of the method of the present invention is proposed through the method of the present invention and the method of the medical electrocardiograph measuring comparative experiment, and the effect verification is carried out at the same time.

[0027] experimental design

[0028] This experiment invited 20 volunteers, including 10 males and 10 males, aged between 19-22 years old. Before the start of the experiment, introduce the experimental process to the subjects in detail, and conduct relevant experiments after obtaining their consent. Each group of experiments lasted about 1-2 minutes. The clock alarm program written in C language was used as a timer, and the iPPG data and ECG data of the subjects were recorded synchronously every 5s. Each group recorded 10 groups of data.

[0029] During the experiment, the subjects were required to sit naturally about...

Abstract

The invention discloses a noncontact measurement method for human heart rate and respiration, and belongs to the technical field of heart rate and respiration measurement methods. The purpose of the invention is to improve signal acquisition robustness by using face detection and a fast tracking algorithm. The real-time and continuous measurement of heart rate and respiration is achieved by appropriately reducing the sampling rate of a camera and setting a sliding window. The method comprises a first step of acquiring data; a second step of preprocessing; and a third step of obtaining the heart rate and the respiratory rate. The method has a result substantially the same as the measurement result of a medical electrocardiograph. Compared with the prior art, the method uses the face detection and the CSK fast tracking algorithm to reduce the artifact due to motion and improve the signal acquisition robustness.

Description

technical field [0001] The invention specifically relates to a non-contact measurement method for human heart rate and respiration, and belongs to the technical field of heart rate and respiration measurement methods. Background technique [0002] Respiration and heart rate are the most important physiological parameters of the human body, which reflect the physiological state and health information of the human body in real time. Its stability directly reflects the function of the heart and lungs, and is two important physiological indicators of human health. : According to the report, at present, it is estimated that there are about 290 million patients with cardiovascular diseases in the country, including about 270 million patients with hypertension, about 2.5 million patients with myocardial infarction, and about 4.5 million patients with heart failure. Cardiovascular diseases. By monitoring heart rate, many cardiovascular diseases can be prevented in advance, such as...
