Contactless Measurement of Vital Signs Using Thermal and RGB Cameras: A Study of COVID 19-Related Health Monitoring

Abstract

In this study, a contactless vital signs monitoring system was proposed, which can measure body temperature (BT), heart rate (HR) and respiration rate (RR) for people with and without face masks using a thermal and an RGB camera. The convolution neural network (CNN) based face detector was applied and three regions of interest (ROIs) were located based on facial landmarks for vital sign estimation. Ten healthy subjects from a variety of ethnic backgrounds with skin colors from pale white to darker brown participated in several different experiments. The absolute error (AE) between the estimated HR using the proposed method and the reference HR from all experiments is 2.70±2.28 beats/min (mean ± std), and the AE between the estimated RR and the reference RR from all experiments is 1.47±1.33 breaths/min (mean ± std) at a distance of 0.6–1.2 m.

Remotely Monitoring COVID-19 Patient Health Condition Using Metaheuristics Convolute Networks from IoT-Based Wearable Device Health Data

“…Fan Yang et al [ 28 ] defined one method for measuring vital signs without the use of a face mask, as was proposed in this research that uses latent heat and an RGB camcorder to measure a person’s temperature of the body, heartbeat, and breathing rates (BRs). There were three areas of interest (AOIs) found by using facial landmarks and the convolution neural network (CNN) face detector.…”

A UAV‐based portable health clinic system for coronavirus hotspot areas

“…It informs the householder of its presence and senses the person's approach through a mounted motion detection sensor. Then it gives guidance instructions for getting the required information by measuring the vital signs of a person, including the body temperature, heart rate, oxygen saturation of the blood (SpO 2 ), blood pressure, and respiratory rate, through recording a video for his/her face and processing the images onboard as in [ 25 ], a detailed primary screening process is shown in Figure 4 .…”
