IISER Bhopal Innovators develop low cost ‘Crowd and Mask’ Monitoring System

Researchers at the Indian Institutes of Science Education and Research (IISER), Bhopal have developed a low cost AI-powered monitoring system to prevent the spread of COVID-19 on campus.

With the institute set to begin the process of bringing students back to the campus in phases, the "Crowd and Mask" monitoring system will help in maintaining a minimum of three-feet social distance among students and replicate manual policing to ensure that the COVID-19 prevention norms are being followed, officials said.

"We wanted a simple advisory system to warn students breaching social distancing norms at selected locations.

"The innovators used the principles of Artificial Intelligence and Machine Learning (AI-ML) in a high definition camera attached to a microchip computer and a 5V battery in a 3D printed case to monitor the movement of people in the campus," said P B Sujit, Associate Professor, Department of Electrical Engineering and Computer Science, IISER Bhopal.

If the camera detects that the social distancing and mask norms were not being followed, the device starts alerting the crowd with a pre-recorded message, he said.

"The device was initially deployed at the campus in October last year and continuously improved till it became stable with minimum false alarms. As a result, people have become sensitive to the social distancing violation and are following the safety protocol with more caution," he added.

The innovators are planning to open source the complete system along with a how-to-use tutorial for the betterment of society in such disruptive COVID-19 times, officials said.

"Given the opportunity, this device can be deployed at various crowded public places to ensure that the basic safety rules are not violated in this tough time of COVID-19 pandemic," Sujit said.
