Modeling of cylindrical scene in CCTV systems with motorized camera

One of the main tasks of monitoring service operators is the video data inspection in order to search for interesting events. Assuming a CCTV system equipped with a motorized camera operating in a pan cycle (a quite typical situation), we propose a new visualization and event search method consisting: first, in generation of a cylindrical (panorama) scene model, and second, in creation of video sequences containing the selected panorama parts for a convenient automatic and/or manual video analysis.
