Physical Distancing and Crowd Density Monitoring
Fig . 1 : A high-level overview of the physical distance monitoring system using computer vision and streaming analytics . The color legend indicates the frequency with which each component is updated . Camera calibration denoted by the yellow box is needed only once for each input video . Components in green boxes are updated continuously in real-time , components in blue boxes are updated daily , whereas the person detection model needs to be updated as per requirement .
The person detection model makes predictions to detect people in each frame independent of previous and future frames . This does not allow to track the trajectory of the movement of people across frames , which is crucial to monitor the movement of people . We use a high-speed
