T365 0-113 Sentence denotes Physical Distancing was monitored for each cell using a pre-trained YOLO model for detecting people in that cell.
T366 114-163 Sentence denotes Relative distance was then calculated as follows:
T367 164-275 Sentence denotes The pairwise distance between two people is the distance between the two similar corners of their bounding box.
T368 276-397 Sentence denotes In order to minimize the camera’s vanishing point effect, the distance was then compared to their bounding box diameters.
T369 398-556 Sentence denotes If the distance was less than the longest diameter, it was assumed that the relative distance between those people was violating the Physical Distancing rule.
T370 557-659 Sentence denotes For the following example, the view from a fixed camera was divided into several polygons (geofences).
T371 660-806 Sentence denotes This can result in the creation of separate geofences (indicated by the IndoorGML nodes if they were in the building) from the camera’s viewpoint.
T372 807-939 Sentence denotes The number of people per geofence polygon and the number of times that people were closer than two metres were reported to the IoCT.
T373 940-1089 Sentence denotes The following figure (Figure 11) shows a frame of multiple geofences in an outdoor area, the detected people, and the Physical Distancing violations.
T374 1090-1283 Sentence denotes The video demo of this scene is attached in Supplementary Materials which shows the people count online when they entered or exited the geofences, as well as the physical distancing violations.
T375 1284-1348 Sentence denotes Outdoor geofences can be connected to the IndoorGML graph nodes.
