Abstract

According to the non-contact heart rate measurement method and device and the computer equipment, the face image is obtained in real time; the method comprises the following steps: acquiring a human face image, extracting a region of interest (ROI) of the human face image, performing image data accumulation on the ROI, performing high-quality signal region screening on the ROI when accumulation time reaches a preset time threshold value to obtain a human body photoplethysmography (PPG) signal, and performing singular spectrum analysis on the human body PPG signal to obtain a heart rate value. According to the method, the influence of the environment on the non-contact heart rate measurement is reduced and the accuracy of the non-contact heart rate measurement is improved by adopting a high-quality signal area screening and singular spectrum analysis-based heart rate calculation method.

Description

technical field [0001] The invention relates to the field of image processing, in particular to a non-contact heart rate measurement method, device and computer equipment. Background technique [0002] The current heart rate measurement methods are mainly divided into two types, one is contact measurement and the other is non-contact measurement. The contact-type heart rate measurement method is through the photoelectric volume method, the transmission type blood oxygen method, and the electrocardiographic signal method. Although the contact-type heart rate measurement method has high accuracy, the contact-type heart rate measurement method requires the human body to wear or entrain the measurement equipment. This brings a lot of inconvenience and discomfort to the user. The non-contact heart rate measurement method refers to capturing the natural light of the human body for 5s to 30s or monitoring the fluctuation of the body surface through ordinary cameras or radars, extr...
