Abstract

A system for providing stitched video from a first camera and a second camera to an electronic display system includes a processing circuit configured to associate a view a first camera with an approximate location. The processing circuit is further configured to build relationship data between the first camera and a second camera using the approximate location. The processing circuit is further configured to transform video from the first camera relative to video from the second camera, the transformation based on the relationship data. The processing circuit is further configured to use the transformed video to cause the stitched video to be provided to the electronic display system.

Claims

1. A system for providing stitched video from a first camera and a second camera to an electronic display system, comprising:

a processing circuit configured to associate a view a first camera with an approximate location and to build relationship data between the first camera and a second camera using the approximate location, wherein the processing circuit is further configured to transform video from the first camera relative to video from the second camera, the transformation based on the relationship data, the processing circuit further configured to use the transformed video to cause the stitched video to be provided to the electronic display system;

the processing circuit is configured to calculate a geometric representation of a field-of-view for the first camera and the second camera using location information and camera property information associated with each camera, wherein the first camera is a movable camera;

the processing circuit is configured to build the relationship data by comparing the geometric representations, wherein

building the relationship data comprises updating a data structure that relates at least one of an adjacent camera pair and an adjacent field-of-view pair; and

the processing circuit determines that a field-of-view is adjacent to another field of view or that a camera is adjacent another camera by determining whether the geometric representations of the fields-of-view intersect.

2. The system of claim 1, wherein the geometric representation of the field of view is at least one of a two-dimensional shape and a three-dimensional shape;

and

wherein the processing circuit is configured to build the relationship without manual input from a user.
