Abstract
Non-contact long-distance monitoring system could provide benefit for examination and monitoring of patients without infectious contamination and rapidly recognize infected patients in a high flow of people. Although on-body wearable sensing systems and infrared camera were widely developed for preventing COVID-19, however, there are still demands on the non-contact sensing systems for the public area of people with masks. In this paper, we present an Image-based non-contact breathing monitoring system for people wearing masks. By calculating the RGB values in nostrils region on the mask, the respiratory rate was successfully been obtained. The signal to noise ratio and influence of the size of the region, illumination condition and CMOS sensors were also studied. With appropriate measuring region, the monitoring system was able to record breath even the light illumination was 1 lumen.
