A Contactless Solution for Monitoring Social Distancing: A Stereo Vision Enabled Real-Time Human Distance Measuring System

Ziran, H.; Dahnoun, N.

Covid-19 has significantly impacted the entire world since late 2019. Keeping a safe social distance while staying in enclosed public spaces has become an important aspect for controlling the spread of the virus. Hence, it is crucial to monitor and ensure that people are keeping a safe distance in densely populated areas. Current human distance measuring systems rely on sensors to achieving such a task. However, the sensors that are handed out might act as a medium for the virus to spread. In this paper, a stereo vision enabled contactless human distance measuring system is presented. The developed system uses a stereo camera to detect people and measure the distance between each person. The system is capable of measuring the distance between multiple people with a precision of around 10cm in real-time (15FPS). Depending on the social distancing rules, the system can send out warnings or alerts if the distance between two people is smaller than the threshold value. © 2021 IEEE.
