Physical Distancing and Crowd Density Monitoring
Fig . 4 : ESP Dashboard with real time visualizations of physical distance violation clusters displaying the results in an anonymous fashion by blurring the individuals in live streaming of camera feed . In the middle , we view the violations clusters with respect to its mapping to true physical world . On the right side , there are gauges showing the count of people in each geofence . The bottom part of the dashboard has the alert table which has the list of alerts along with the timestamp of the alert origination and the alert description .
VISUALIZATIONS Heatmap Visualizations
We use heat maps superimposed on the original images to answer a few different questions . The first heat map is generated by aggregating the positions of every detected person over a given time interval . In our examples we use a time interval of 5 minutes which allows us to study how the heatmaps change over time . This heat map on Figure 5 allows us to answer questions about overall traffic flow and can be used as an indication of where cleaning crews might need to spend additional time due to heavier traffic .
