Claim 0:
1. A method of calibrating a moving camera capturing a sporting event, comprising:
identifying, by a computing system, a live broadcast video feed for a sporting event, the live broadcast video feed comprising a plurality of video frames captured by a camera located in a sporting venue;
receiving, by the computing system, pose data for one or more players;
removing, by the computing system, the one or more players from the plurality of video frames based on the pose data to generate a plurality of empty video frames;
analyzing, by the computing system, the plurality of empty video frames to identify a flow field between successive video frames of the plurality of empty video frames;
generating, by the computing system, a homography matrix for each empty video frame based on the flow field between the successive video frames; and
calibrating, by the computing system over a network, the camera based on the homography matrix generated for each empty video frame of the plurality of empty video frames by applying each homography matrix to a corresponding video frame of the plurality of video frames.
