Abstract
This invention concerns wide-area video surveillance systems. In a first aspect the invention is a surveillance network, in another aspect the invention is a virtual observer, and in a further aspect the invention is a method for operating a virtual observer. Each segments or frame of video, from each camera of the network is associated with the following trajectory parameters; a time and a spatial position, and possibly a radius, orientation, resolution and field of view, and stored for later recall.

- 13. A virtual observer in a wide area video surveillance network, comprising a computer having access to recall segments or frames of video recorded and stored, and a monitor on which it displays a view constructed from segments or frames recorded at different times, or from different cameras, or both, and associated with the trajectory parameters of time and spatial position.

16. A method of operating a virtual observer in a wide area video surveillance network, comprising the following steps:
-
receiving an input of the location of the virtual observer on a map of the network; receiving an input of the query operators and observation parameters for the location; determining trajectory parameters corresponding to the specified location, query operators and observation parameters;
recalling stored segments or frames of video associated with the determined trajectory parameters; and
,synthesizing a view to be displayed from the recalled video segments or frames. - View Dependent Claims (17, 18, 19, 20)
