Method for measuring heart rate and respiratory frequency of human body

Abstract

The invention relates to a method for measuring the heart rate and the respiratory frequency of a human body. The method comprises the following steps of 1, obtaining a video image of a tested object; 2, resolving the video image into an image frame series; 3, inserting and generating N frames of images in the adjacent image frames; 4, detecting the position of a located region of a face in each frame of image; and 5, performing statistics according to the change of the position of the located region of the face in an image frame system to obtain the face fluctuation frequency of the tested object, i.e. the heart rate of people. The method has the advantages that a plurality of frames of images are inserted and generated in the image frames of the video image of the tested object; after the video slowdown at a certain ratio, the heart rate and the respiratory frequency of the human body are obtained according to the fluctuation and color change conditions of the located regions of the face and the chest cavity in the slowdown video image frame; the remote heart rate and breath monitoring is realized; the remote real-time monitoring on the heart rate and the breath of the tested object is facilitated; and the body condition of the tested object can be mastered in time.

Description

technical field [0001] The invention relates to a method for measuring vital parameters of a human body, in particular to a method for measuring heart rate and respiratory rate of a human body by using image recognition technology. Background technique [0002] Heartbeat and respiration are important parameters of human life. Accurate and convenient measurement of human heartbeat rate and respiration rate has an important reference role for the physiological health of modern people. The traditional method of measuring the heart rate of the human body is mainly through pulse detection. The existing detection methods include heart rate monitors, heart rate monitors, etc., but they are all contact detection methods, which require close contact with the measured person. The prior art (CN101959458A) also discloses a method of measuring heart rate using visible light images, by receiving multiple visible light images corresponding to the skin of the subject close to the capillarie...

Problems solved by technology

[0004] In order to solve the technical problem in the prior art that the heartbeat rate and breathing rate of the human body cannot be measured remotely and accurately, the present invention provides a method for remotely measuring the heartbeat rate and breathing rate of the human body based on image processing, by processing the image captured by the camera , and detect changes in the position of the face and chest through image recognition technology, determine the generation of heartbeat and respiration through the changes in the position of the face and chest, and then obtain the heartbeat rate and respiration rate of the human body through statistics, realizing long-distance heartbeat and respiration measurement , which greatly facilitates people's life
