The monitoring arrangement includes a first video camera (1) with a fixed wide-angle lens (2). An evaluation arrangement (3) is coupled to the first video camera for the recognition and localization of changes in the image section (5) recorded by the first video camera. A second video camera (8) is provided with a lens (10) with larger focus distance, which is preferably, adjusted by a motor, and with a positioning drive (9) for an adjustment of the view direction of the second video camera. There is a control arrangement (7) for positioning the second video camera in the view direction on the area of the image change in the image section.

Description

Die Erfindung betrifft eine Video-Überwachungseinrichtung.The invention relates to a video surveillance device.

Aus "Funkschau I Spezial", 1990, Seiten 20 bis 23 ist eine Video-Überwachungseinrichtung mit einer Vielzahl von Video­ kameras bekannt, deren Videosignale über eine Video-Kreuz­ schiene je nach Bedarf auf unterschiedliche Monitore schalt­ bar sind. Dabei werden neben Videokameras mit fester Blick­ richtung und fester Brennweite auch bewegliche Videokameras mit Vario-Objektiven eingesetzt, um die Identifikation feiner Details in dem Überwachungsbereich zu ermöglichen; die ent­ sprechende Steuerung der Videokameras erfolgt dabei durch Be­ dienpersonal in einer Video-Zentrale. Zur Entlastung des Be­ dienpersonals von ermüdenden Beobachtungsaufgaben werden Vi­ deo-Controller (Video-Bewegungsmelder) eingesetzt, die das Kamerabild nach Änderungen bewerten und diese mit einstell­ baren Alarmkriterien vergleichen.From "Funkschau I Spezial", 1990 , pages 20 to 23, a video monitoring device with a large number of video cameras is known, the video signals of which can be switched to different monitors via a video crossbar as required. In addition to video cameras with a fixed line of sight and a fixed focal length, movable video cameras with zoom lenses are used to enable the identification of fine details in the surveillance area; The corresponding control of the video cameras is carried out by operating personnel in a video center. To relieve the operating personnel of tiring observation tasks, video de-controllers (video motion detectors) are used, which evaluate the camera image after changes and compare them with adjustable alarm criteria.

Der Erfindung liegt die Aufgabe zugrunde, eine noch weiter­ gehende Automatisierung der Überwachungsfunktionen zu errei­ chen.The invention has for its object one more to achieve ongoing automation of the monitoring functions chen.

Gemäß der Erfindung wird die Aufgabe durch die in Anspruch 1 angegebene Video-Überwachungseinrichtung gelöst. According to the invention the object is achieved by the in claim 1 specified video surveillance device solved.  

Vorteilhafte Weiterbildungen der erfindungsgemäßen Video-Überwachungseinrichtung sind den Unteransprüchen zu entneh­ men.Advantageous further developments of the invention Video monitoring device can be found in the subclaims men.

Der Vorteil der erfindungsgemäßen Video-Überwachungseinrich­ tung liegt darin, daß nicht nur eine Alarmsituation automa­ tisch erkannt wird, sondern daß zusätzlich das alarmauslö­ sende Objekt für das Bedienpersonal sofort detailliert dar­ gestellt und bei Bewegung verfolgt wird.The advantage of the video surveillance device according to the invention tion is that not only an alarm situation automa table is recognized, but that in addition the alarm trigger send object immediately for the operating personnel posed and tracked when moving.

Zur weiteren Erläuterung der Erfindung wird im folgenden auf die Figur der Zeichnung Bezug genommen, die ein Ausführungs­ beispiel der erfindungsgemäßen Video-Überwachungseinrichtung zeigt.To further explain the invention, the following is based on the figure of the drawing referred to an execution example of the video monitoring device according to the invention shows.

Zur Beobachtung eines vorgegebenen Überwachungsbereichs ist eine erste feste Videokamera 1 mit einem Weitwinkelobjektiv 2 über eine Auswerteeinrichtung 3 an einer Video-Kreuz schiene 4 angeschlossen. Die Auswerteeinrichtung 3 unterteilt den von der Videokamera 1 erfaßten Bildausschnitt 5 in unterschied­ liche Auswertefenster 6, innerhalb derer Bildänderungen de­ tektiert und an eine Steuereinrichtung 7 übertragen werden.To observe a predetermined monitoring area, a first fixed video camera 1 with a wide-angle lens 2 is connected via an evaluation device 3 to a video crossbar 4. The evaluation device 3 divides the image section 5 captured by the video camera 1 into different evaluation windows 6 , within which image changes are detected and transmitted to a control device 7 .

Der ersten Videokamera 1 ist eine zweite Videokamera 8 zu­ geordnet, die ausgangsseitig ebenfalls an der Video-Kreuz­ schiene 4 angeschlossen ist. Je nach Eingabe über eine Be­ dieneinrichtung 11 werden die Videosignale der beiden Video­ kameras 1 und 8 auf unterschiedliche Monitore 12a, 12b durch­ geschaltet. Die zweite Videokamera 8 kann über einen Positio­ nierantrieb 9 in unterschiedliche Blickrichtungen geneigt und geschwenkt wird. Darüber hinaus weist die zweite Videokamera 8 ein Objektiv 10 mit motorisch variabler Brennweite auf. Die Ansteuerung des Positionierantriebs 9 und des Objektivs 10 erfolgt durch die Steuereinrichtung 7, wobei die Positionie­ rung der zweiten Videokamera 8 in Abhängigkeit von unter­ schiedlichen, in einem Speicher 13 hinterlegten Positionen erfolgt. Dabei ist jedem Auswertefenster 6 in der Auswerte­ einrichtung 3 jeweils eine Position in dem Speicher 13 zuge­ ordnet.The first video camera 1 is assigned a second video camera 8 , which is also connected on the output side to the video crossbar 4 . Depending on the input via a control device 11 , the video signals of the two video cameras 1 and 8 are switched through to different monitors 12 a, 12 b. The second video camera 8 can be tilted and pivoted in different viewing directions via a positioning drive 9 . In addition, the second video camera 8 has a lens 10 with a motor-variable focal length. The positioning drive 9 and the lens 10 are actuated by the control device 7 , the positioning of the second video camera 8 taking place as a function of different positions stored in a memory 13 . Each evaluation window 6 in the evaluation device 3 is assigned a position in the memory 13 .

Die erste Videokamera 1 liefert ein Übersichtsbild des zu überwachenden Bereichs. Wenn ein Objekt in diesen Überwa­ chungsbereich eindringt, wird eine entsprechende Bildänderung von der Auswerteeinrichtung 3 detektiert und anhand der Aus­ wertefenster 6 lokalisiert. Die Auswerteeinrichtung 3 meldet die Detektion der Steuereinrichtung 7, die sofort über die Videokreuzschiene 4 das Bild der Videokamera 1 auf den Moni­ tor 12a und das Bild der Videokamera 8 auf den Monitor 12b aufschaltet. Die zweite Videokamera 8 wird durch die Steuer­ einrichtung 7 in die dem Auswertefenster 6 mit der darin detektierten Bildänderung zugeordneten Position gesteuert und liefert ein detailliertes Bild des alarmauslösenden Objekts. Wird nachfolgend von der Auswerteeinrichtung 3 ein anderes Auswertefenster 6 mit darin detektierter Bildänderung gemeldet, so wird die zweite Videokamera 8 nachpositioniert; dadurch ist eine detailliertere Verfolgung des Objekts mög­ lich. The first video camera 1 provides an overview image of the area to be monitored. If an object enters this monitoring area, a corresponding image change is detected by the evaluation device 3 and localized on the basis of the evaluation window 6 . The evaluation device 3 reports the detection of the control device 7, which immediately on the video crossbar 4 tor the picture of the video camera 1 to the Moni 12 a and the image of the video camera aufschaltet b 8 to the monitor 12th The second video camera 8 is controlled by the control device 7 in the position assigned to the evaluation window 6 with the image change detected therein and provides a detailed image of the object triggering the alarm. If another evaluation window 6 with an image change detected therein is subsequently reported by the evaluation device 3 , the second video camera 8 is repositioned; this enables a more detailed tracking of the object.

Für unterschiedliche Überwachungsbereiche können an die Vi­ deo-Kreuz schiene 4 mehrere Kamerapaare entsprechend den bei­ den Videokameras 1 und 8 angeschlossen werden.For different surveillance areas, 4 pairs of cameras can be connected to the Vi deo crossbar 4 in accordance with the video cameras 1 and 8 .
