In California, startup Airspace Systems has created a software application that allows public agencies to analyze video streams captured by drones and detect people who are not physical distancing or wearing face masks. The software can also process video captured by ground-based cameras as well. The system does not use facial recognition or save images, but instead generates aggregate data on how many people in a given area are maintaining physical distancing and wearing masks. The data can then be used to provide communities with public health messages, cleaning crews, and law enforcement depending on local and state policies.
