Claim Text:
1. A system for reconstructing a scene observed by a virtual observer in a wide area video surveillance network comprising: (a) plural mobile video cameras mounted on different vehicles that move in the wide area video surveillance network, the plural mobile video cameras having an external view, and wherein each segment or frame of video recorded by the plural mobile video cameras is stored together with corresponding trajectory parameters including a time of the segment or frame of video, a spatial position of a first camera of the plural mobile video cameras, orientation of the first camera, resolution of the first camera and field of view of the first camera; (b) a computer to recall segments or frames of the stored video in response to receiving one or more queries that include observation parameters, so as to enable a view from the virtual observer representing an imaginary camera located at a point in the wide area video surveillance network, the view being defined by the observation parameters and the observation parameters including a source position of the imaginary camera, orientation of the imaginary camera, resolution of the imaginary camera, field of view of the imaginary camera, and visibility radius of the field of view of the imaginary camera by synthesizing together recalled segments or frames that: wherein the synthesizing together the recalled segments or frames includes an operation to merge the recalled segments or frames; and (c) a monitor to display the view from the virtual observer.
