Problems solved by technology

[0005] At present, the traditional heart rate monitoring method is mainly contact type, but because of the complicated operation and the long-term contact with the human skin during the detection process, it will cause some inconvenience and discomfort to the measurer
Moreover, the general measurer needs to be in a static state when measuring the heart rate. When the device is in a state of motion, the recognition accuracy of the device will decrease, so it cannot help special groups such as ADHD patients, athletes, and motor vehicle drivers. The need to measure dynamic heart rate in the state

Abstract

The invention discloses a video-based dynamic heart rate detection method. The method comprises the following steps: S1, video acquisition: carrying out continuous video recording on a human face needing to be tested by utilizing a common camera; s2, face recognition and tracking: detecting and recognizing face data information in the video frame, calibrating face key points, and keeping face tracking; s3, motion compensation: generating an interpolation image for inter-frame motion compensation of the video image by using a full convolutional neural network; s4, illumination compensation; S5,interested skin region signal extraction; s6, heart rate estimation: performing heart rate estimation by utilizing photoplethysmography, signal finding, artifact removal, spectral analysis and ECG-like signal reconstruction technologies; and S7, obtaining a heart rate detection signal. A non-skin-contact detection method is adopted, discomfort of a human body cannot be caused, and the detection accuracy is high.

Description

technical field [0001] The invention belongs to the technical field of heart rate detection, in particular to a video-based dynamic heart rate detection method. Background technique [0002] Heart rate is one of the most commonly measured parameters of the human body, and it is crucial to determine individual health, so heart rate monitoring plays an irreplaceable role in the monitoring of human health. [0003] Face tracking is to continue to capture information such as the position and size of the face in subsequent frames on the premise of detecting the face, including face recognition and face tracking technology. The traditional face recognition technology is mainly based on face recognition of visible light images, especially when the ambient light changes, the recognition effect will drop sharply, and there are still problems such as object occlusion and large differences between side faces and front faces. Traditional face tracking is based on this, and the natural ...
