It is essential to maintain social distance and avoid large mob gatherings at one place to break the chain of corona virus infection, but maintaining these things is not that much easy. People knowingly or unknowingly, gather, roam on the streets & break the rules. Hence Keeping an eye on all these activities is not an easy job. The proposed system is an automatic method for controlling crowd in this pandemic situation, where crowd gatherings should be avoided on large basis. We have proposed a system which will keep a watchful eye on crowd gathering with help of RPi camera, as crowd is detected the system will give a alert to authorities that they will take actions against the crowd gatherings and restrict the public from areas where crowds are restricted to be gather. The main aim of the survey is to be found how to avoid unnecessary gatherings where crowd is restricted! and if crowd gathers unnecessarily, system can alert the respective authorities and crowd can be minimized.
