Problems solved by technology

According to the difference in detection technology and method, it can be divided into two types: contact type and non-contact type. Among them, contact type detection has greater discomfort, may cause stimulation or pain, and even cause some physiological changes, thus affecting the detection results. the accuracy of
At the same time, the contact detection method is not suitable for long-term contact with the human body, so it is not suitable for long-term detection and daily monitoring at any time
Moreover, for patients with hand skin injuries, patients with mental illness, infants and other patients who cannot cooperate autonomously, it is not suitable to use electrodes or sensors to touch their bodies, resulting in obvious limitations in contact heart rate detection.

Abstract

The invention discloses a non-contact heart rate detection device based on the BCG principle. An imaging device is fixed on the head of a tested object, and the targeted object keeps the head stationary at any position in any posture for video collection for 30 seconds or more. By tracking any stationary target in the video and processing a signal, the heart rate of the tested object can be obtained under a complex environment, and the accurate non-contact heart rate detection is achieved.

Description

technical field [0001] The invention belongs to the technical field of human health monitoring, and relates to a non-contact heart rate detection method based on the BCG principle, in particular to a non-contact heart rate detection method based on the BCG principle and head movement. Background technique [0002] Heart rate refers to the number of heartbeats performed by the human heart per minute, and it is a barometer of human physiological health. The heart rate when a person is quiet and not exercising a lot is called the resting heart rate. According to the difference in detection technology and method, it can be divided into two types: contact type and non-contact type. Among them, contact type detection has greater discomfort, may cause stimulation or pain, and even cause some physiological changes, thus affecting the detection results. accuracy. At the same time, the contact detection method is not suitable for long-term contact with the human body, so it is not s...
