Multi-video navigation

摘要

A video tracking system includes a user interface configured to facilitate tracking of a target between video cameras. The user interface includes user controls configured to assist a user in selecting video cameras as the target moves between fields of view of the video cameras. These user controls are automatically associated with specific cameras based on a camera topology relative to a point of view of a camera whose video data is currently being viewed. The video tracking system further includes systems and methods of synchronizing video data generated using the video cameras and of automatically generating a stitched video sequence based on the user selection of video cameras. The target may be tracked in real-time or in previously recorded video and may be track forward or backwards in time.

1. A method comprising:
identifying a first member of a plurality of cameras; identifying a first topological relationship between the first member of the plurality of cameras and a second member of the plurality of cameras; identifying a second topological relationship between the first member of the plurality of cameras and a third member of the plurality of cameras, the first topological relationship and the second topological relationship being relative to a viewpoint of the first camera; presenting video data generated using the first member of the plurality of cameras in a user interface, the user interface including a first user control and a second user control; associating the second member of the plurality of cameras with the first user control based on the topological relationship between the first member of the plurality of cameras and the second member of the plurality of cameras; associating the third member of the plurality of cameras with the second user control based on the topological relationship between the first member of the plurality of cameras and the third member of the plurality of cameras; receiving a user selection of the first user control; presenting video data generated using the second member of the plurality of cameras in the user interface based on the received user selection; and wherein the user interface includes a plurality of user controls that comprises, in part, the first, second and third user controls, the plurality of user controls including a fourth user control that is not associated with any of the plurality of cameras, the method further comprising graying out the fourth user control to indicate a lack of associate with any of the plurality of cameras.
