Abstract

Innerhalb eines bestimmten Überwachungsbereiches werden durch sich bewegende Objekte (OB) hervorgerufene Kontraständerungen mit zwei Fernsehkameras erfaßt, mittels automatischer Bildauswertung bewertet und zur Alarmgabe herangezogen. Within a given monitoring area (OB) are detected caused changes in contrast with two television cameras by moving objects, evaluated by means of automatic image analysis and used for alarm signal. Zwei zusammengehörige Fernsehbilder werden gemeinsam ausgewertet. Two related television images are evaluated together. Dabei sind die Fernsehkameras (K1,K2) in einem bestimmten, gegenüber einer üblichen Stereo-Anordnung jedoch großen Abstand (d) voneinander angeordnet und bilden eine gemeinsame Abstandslinie (AL), so daß sich das Beobacht ungsvolumen (GA) bei unterschiedlicher Blickrichtung im Blickfeld der beiden Kameras (K1,K2) befindet. In this large distance (d), the television cameras (K1, K2) are arranged at a certain, relative to a conventional stereo arrangement, however, and form a common distance line (AL), so that the Beobacht ungsvolumen (GA) at different viewing direction in the field of view of the two cameras (K1, K2) is located. Aufgrund der vorgegebenen Positionen der Kameras, dh bestimmter Kamera-Abstand (d) und gegebene Raumwinkel (ε1, ε2, α1, α2) der jeweiligen Kamera und unter Berück sichtigung der Objektiv-Brennweiten wird der tatsächliche Ort, die wahre Größe und die äußere Gestalt des Objekts (OB) ermittelt und hieraus ein Alarmkriterium abgeleitet. Due to the predetermined positions of the cameras, ie specific camera distance (d) and given solid angle (ε1, ε2, α1, α2) of the respective camera and taking into account the lens focal length is the actual location, the true size and the outer shape the object (OB) is determined and deriving an alarm criterion.
