Interaktives Überwachungssystem

摘要

A process is disclosed for observing or monitoring an area in space. Images of the area (1) to be observed/monitored are taken by means of at least one camera (2), the converted image information is sent to a control computer (3), the control computer (3) checks the images for changes in the observed area (1), the main direction and/or speed of optically perceptible changes (movements) in the observed area are analysed by analysis of the optical flow, the analysis result is converted into control instructions sent to a controller (4) that mechanically moves the camera, and if required the position and/or size of the image section that may be taken by the camera is modified. Also disclosed is an interactive surveillance system with a control computer (3) connected to or integrated into a camera (2) or into one among several cameras. The control computer (3) receives and processes the data recorded by the camera(s) and sends control signals to a zoom lens (5). A mechanical controller (4) reacts to impulses from the control computer (3) and modifies the recording section of the area (1) to be observed or the size of the image section (5). A device reacts to signals from the control computer (3) and opens a normally closed passage.
