Abstract
A monitoring system ( ) includes a video camera ( ) which generates images of a monitored area. A computer ( ) receives the images from the video camera, and contains a digitized map ( ) of the monitored area. One of the detected images ( ) is saved as a reference image. An operator defines a first region ( ) corresponding to a selected portion of the monitored area, as viewed in the reference image, and defines a second region ( ) which corresponds to the selected portion of the area as viewed on the map. Subsequent images from the camera are compared to the reference image, in order to identify an object of interest, and a first point associated with the object is identified. If the first point is within the first region, a warp transformation of the first point from the first region to the second region is carried out, in order to identify within the second region a second point which corresponds to the first point, and which identifies the location on the map of the object of interest.
