Tracking positions using a scalable position tracking system

A method comprising:

• receiving, by a first camera client, a first plurality of frames of a first video from a first camera of an array of cameras, the array of cameras positioned above a space, each camera of the array of cameras configured to capture a video of a portion of the space, the space containing a person, each frame of the first plurality of frames showing the person within the space;
• for a first frame of the first plurality of frames:
• determining, by the first camera client, a first bounding area around the person shown in the first frame;
• and
• generating, by the first camera client, a first timestamp of when the first frame was received by the first camera client;
• for a second frame of the first plurality of frames:
• determining, by the first camera client, a second bounding area around the person shown in the second frame;
• and
• generating, by the first camera client, a second timestamp of when the second frame was received by the first camera client;
• for a third frame of the first plurality of frames:
• determining, by the first camera client, a third bounding area around the person shown in the third frame;
• and
• generating, by the first camera client, a third timestamp of when the third frame was received by the first camera client;
• receiving, by a second camera client separate from the first camera client, a second plurality of frames of a second video from a second camera of the array of cameras, each frame of the second plurality of frames showing the person within the space;
• for a fourth frame of the second plurality of frames:
• determining, by the second camera client, a fourth bounding area around the person shown in the fourth frame;
• and
• generating, by the second camera client, a fourth timestamp of when the fourth frame was received by the second camera client;
• for a fifth frame of the second plurality of frames:
• determining, by the second camera client, a fifth bounding area around the person shown in the fifth frame;
• and
• generating, by the second camera client, a fifth timestamp of when the fifth frame was received by the second camera client;
• determining, by a camera server separate from the first and second camera clients, that the first timestamp falls within a first time window;
• in response to determining that the first timestamp falls within the first time window, assigning, by the camera server, coordinates defining the first bounding area to the first time window;
• determining, by the camera server, that the second timestamp falls within the first time window;
• in response to determining that the second timestamp falls within the first time window, assigning, by the camera server, coordinates defining the second bounding area to the first time window;
• determining, by the camera server, that the third timestamp falls within a second time window that follows the first time window;
• in response to determining that the third timestamp falls within the second time window, assigning, by the camera server, coordinates defining the third bounding area to the second time window;
• determining, by the camera server, that the fourth timestamp falls within the first time window;
• in response to determining that the fourth timestamp falls within the first time window, assigning, by the camera server, coordinates defining the fourth bounding area to the first time window;
• determining, by the camera server, that the fifth timestamp falls within the second time window;
• in response to determining that the fifth timestamp falls within the second time window, assigning, by the camera server, coordinates defining the fifth bounding area to the second time window;
• processing, by the camera server, the coordinates assigned to the first time window by:
• calculating, by the camera server, based at least on the coordinates defining the first bounding area and the coordinates defining the second bounding area, a combined coordinate for the person during the first time window for the first video from the first camera;
• and
• calculating, by the camera server, based at least on the coordinates defining the fourth bounding area, a combined coordinate for the person during the first time window for the second video from the second camera;
• after processing the coordinates assigned to the first time window, processing the coordinates assigned to the second time window by:
• calculating, by the camera server, based at least on the coordinates defining the third bounding area, a combined coordinate for the person during the second time window for the first video from the first camera;
• and
• calculating, by the camera server, based at least on the coordinates defining the fifth bounding area, a combined coordinate for the person during the second time window for the second video from the second camera.
