1. A system, comprising:
a communication interface configured to:
receive a transmission of a central video feed from a first camera; and
receive a respective time-stamped position information from a tracking system; and
a processor coupled to the communication interface and configured to:
calibrate the central video feed against a spatial region encompassed by the central video feed including by:
partitioning at least one frame of the central video feed into a plurality of tiles at a first resolution; and
determining a homography defining placement of augmented reality elements on the at least one frame of the central video feed;
use the received time-stamped position information and the plurality of tiles associated with at least one frame of the central video feed to define a first sub-view of the central video feed, wherein the first sub-view corresponds to a portion of the spatial region encompassed by the central video feed; and
output the first sub-view and the determined homography to a device configured to use the first sub-view and the homography to display the first sub-view.
