Abstract
Description
Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur Benachrichtigung einer mit einer einen Bereich überwachenden Überwachungskamera über ein analoges Datennetz verbundenen Netzeinheit bei einem von der Überwachungskamera zu detektierenden Ereignis.The invention relates to a method and a device for notifying a network unit connected to an area monitoring camera via an analog data network in an event to be detected by the surveillance camera.
Videoüberwachungssysteme (CCTV) bestehen meistens aus Überwachungskameras, die mit Speichereinheiten zum Speichern der aufgenommenen Videodaten und/oder Monitoren zum Anzeigen der aufgenommenen Videodaten über ein Datennetz verbunden sind. Dabei kann als Datennetz ein analoges oder ein digitales Datennetz wie zum Beispiel ein paketvermittelndes Kommunikationsnetz verwendet werden. Über digitale oder analoge Datennetze können die Überwachungskameras auch mit einer Verarbeitungseinheit wie zum Beispiel einem Computer, einem Server etc. verbunden werden, welche die von der Überwachungskamera aufgenommenen Videodaten bearbeiten kann. Derartige Verarbeitungseinheiten können mittels geeigneter Algorithmen zum Beispiel Bewegungen erkennen (Motion Detection), Objekte wie zum Beispiel Personen, Fahrzeuge, Türen, Fenster, Parkplätze etc. beobachten (Tracking) etc. Bei konventionellen Videoüberwachungssystemen (CCTV Systemen) werden Videobilder bzw. Videodaten meist analog übertragen um dann auf Videowänden mit mehreren Monitoren angezeigt zu werden und/oder analog oder digital gespeichert zu werden. Oft ist es dem Betrachter überlassen die Videobilder auszuwerten und zu interpretieren. Da Bilder von mehreren Kameras kommend nicht alle gleichzeitig auf einer Videowand dargestellt werden können, sondern sequenziell (auch in Gruppen) angezeigt werden, kann es leicht vorkommen, dass Ereignisse nicht angezeigt oder nicht wahrgenommen werden können.Video surveillance systems (CCTV) usually consist of surveillance cameras connected to storage units for storing the captured video data and / or monitors for displaying the captured video data over a data network. In this case, an analog or a digital data network such as, for example, a packet-switching communications network can be used as the data network. Via digital or analogue data networks, the surveillance cameras can also be connected to a processing unit, such as a computer, a server, etc., which can process the video data recorded by the surveillance camera. By means of suitable algorithms such processing units can detect movements (motion detection), observe objects such as persons, vehicles, doors, windows, parking spaces etc. (tracking) etc. In conventional video surveillance systems (CCTV systems), video images or video data usually become analog transferred to then be displayed on video walls with multiple monitors and / or stored analog or digital. It is often left to the viewer to evaluate and interpret the video images. Since images coming from multiple cameras can not all be displayed simultaneously on a video wall, but are displayed sequentially (also in groups), it can easily happen that events can not be displayed or can not be perceived.
Eine intelligente Überwachungskamera gemäss dem Oberbegriff des Anspruchs 1 ist beispielsweise aus Panasonic: "Color cctv camera WV-NP472 Operating instructions", 2002, oder auch AXIS Communications AB; "AXIS 221 Network camera User's manual Rev.1.0", 2005, bekannt. In einem vorbestimmbaren Bildbereich erfasster digitaler Videodaten ist eine Bewegung detektierbar. Die detektierte Bewegung aktiviert einen Alarmausgang der Überwachungskamera. Die von der Überwachungskamera erfassten Bilddaten wie auch der Alarm sind über ein digitales Kommunikationsnetz an ein entsprechend konfigurierten Netzwerkknoten, beispielsweise an einen sogenannten Event Server oder PC übertragbar, wo Bilddaten und Alarminformation in entsprechenden Browser-Fenstern darstellbar sind.An intelligent surveillance camera according to the preamble of
Aus
Die Aufgabe der vorliegenden Erfindung ist darin zu sehen, eine möglichst einfache und effiziente Möglichkeit zur Benachrichtigung einer Netzeinheit bei einem von einer Überwachungskamera detektieren Ereignis vorzuschlagen.The object of the present invention is to provide a possible simple and efficient way to notify a network unit in an event detected by a surveillance camera event.
Die Aufgabe wird erfindungsgemäß jeweils durch die Gegenstände der unabhängigen Patentansprüche gelöst. Weiterbildungen der Erfindung sind in den Unteransprüchen angegeben.The object is achieved in each case by the subject matters of the independent claims. Further developments of the invention are specified in the subclaims.
Ein Kern der Erfindung ist darin zu sehen, dass die von einer digitalen Überwachungskamera aufgenommen Videodaten hinsichtlich zu detektierenden Ereignisse in der Überwachungskamera zumindest teilweise ausgewertet werden. Bei einem positiven Auswertergebnis, also bei der Detektion eines zu detektierenden Ereignisses, wird den Videodaten mindestens ein Hinweisdatum hinzugefügt und über ein analoges Datennetz an eine Netzeinheit übertragen. Bei einem zu detektierenden Ereignis kann es sich zum Beispiel um eine Bewegung im überwachten Bereich, einen Brand, eine Rauchentwicklung, stehende Fahrzeuge, sich bewegende Fahrzeuge (langsam fahrende, falsch fahrende (in Gegenrichtung, Geisterfahrer) etc.), Überwachung von Nischen (Tunnelnischen), eine Manipulation an der Überwachungskamera wie zum Beispiel das Abdecken der Kamera, das Öffnen des Gehäuses, das Verdrehen (Veränderung des sichtbaren bzw. des überwachten Bereichs) der Kamera, ein zu überwachender Gegenstand wie zum Beispiel ein Auto, eine Tür, ein Fenster, eine Eingangsschleuse, ein Parkplatz, ein Gebäude, ein Treppe etc., eine zu überwachende Person etc. handeln. Auch so genannte kontinuierliche Ereignisse wie zum Beispiel das kontinuierliche Einfärben einer Fläche bzw. dem ereignisabhängigen Einfärben einer solchen Linie, Fläche etc. in einem Videobild wird als Ereignisse betrachtet. Ein Hinweisdatum kann eine alphanumerische Nachricht sein, die während der Wiedergabe der Videodaten eingeblendet wird, also mit den Videodaten überlagert wird. Selbstverständlich sind auch ein akustisches und/oder ein graphisches Hinweisdatum vorstellbar. Als graphisches Hinweisdatum könnte zum Bespiel eine Linie, eine Fläche etc. in einer bestimmten Farbe bei den Videodaten eingeblendet werden. Auch Diagramme und das Einblenden einer bestimmten Geometrie bei den ausgewerteten Videodaten sind erfindungsgemäss vorstellbar. Optional zur Übertragung der Videodaten über das analoge Datennetz können die Videodaten auch über ein paketvermittelndes Kommunikationsnetz wie zum Beispiel einem IP-Kommunikationsnetz, einem mobilen Kommunikationsnetz etc. übertragen werden. Dies kann parallel zur analogen Übertragung der Videodaten inkl. Des mindestens einen Hinweisdatums geschehen. Die zumindest teilweise Auswertung der Videodaten erfolgt erfindungsgemäss durch eine Verarbeitungseinheit wie zum Beispiel einer Prozessoreinheit (DSP), einem Hostprozessor etc. in der Überwachungskamera. Nach der Auswertung werden die digitalen Videodaten mit dem mindestens einen Hinweisdatum in analoge Signale gewandelt und über ein analoges Datennetz an die Netzeinheit übertragen. Vorstellbar ist auch, dass die ausgewerteten Videodaten enkodiert und/oder in einer Speichereinheit der Überwachungskamera zwischengespeichert werden. Vor der Digital/Analog-Wandlung werden die gespeicherten enkodierten Videodaten dann wieder mittels einer Dekodiereinheit dekodiert. Als Netzeinheit kann ein Bildausgabegerät, ein Monitor, ein Fernsehgerät, ein Videoprojektor, ein mobiles Bildausgabegerät, eine Videodaten-Verarbeitungsgerät (Computer, Server etc.), eine Netz-Speichereinheit etc. verwendet werden. Die Auswertung der digital aufgenommenen Videodaten kann automatisch abhängig von Ereignissen, Lichtverhältnissen, Umgebungseinflüssen etc. von der Kamera durchgeführt werden. Dabei kann für die Auswertung eine Falschfarbeneinblendung zur Hervorhebung gewisser Merkmale, eine Überlagerung von gespeicherten Videodaten, eine Kontrasterhöhung der Videodaten etc. durchgeführt werden. Selbstverständlich ist es auch denkbar, dass die Auswertung der digital aufgenommenen Videodaten aufgrund manuell eingegebener Kommandos bzw. zusätzlichen Informationen ausgelöst wird. Derartige Kommandos bzw. zusätzlichen Informationen können von einem Computer, einem Server, einer Datenbank etc. über zum Beispiel ein paketvermittelndes Kommunikationsnetz an die Überwachungskamera übertragen werden.A core of the invention is to be seen in that the video data recorded by a digital surveillance camera are at least partially evaluated with regard to events to be detected in the surveillance camera. In the case of a positive evaluation result, that is to say when an event to be detected is detected, at least one reference date is added to the video data and transmitted to a network unit via an analogue data network. An event to be detected may be, for example, a movement in the monitored area, a fire, a smoke, stationary vehicles, moving vehicles (slow-moving, wrong-moving (in the opposite direction, ghost driver) etc.), monitoring of niches (tunnel niches ), a manipulation on the surveillance camera, such as covering the camera, opening the housing, twisting (changing the visible or monitored area) of the camera, an object to be monitored, such as a car, a door, a window , an entrance lock, a parking lot, a building, a staircase etc., a person to be monitored, etc. act. Even so-called continuous events such as the continuous coloring of a surface or the event-dependent coloring of such a line, surface etc. in a video image are considered as events. A reference date can be an alphanumeric message that is superimposed during playback of the video data, that is overlaid with the video data. Of course, an audible and / or graphical reference date are conceivable. For example, a line, an area etc. in a specific color could be displayed as a graphical reference for the video data. Also diagrams and the fading in of a certain geometry in the evaluated video data are conceivable according to the invention. Optionally for transmitting the video data via the analogue data network, the video data can also be transmitted via a packet-switched communications network such as, for example, an IP communications network, a mobile communications network, etc. This can be done parallel to the analog transmission of the video data including the at least one reference date. The at least partial evaluation of the video data is carried out according to the invention by a processing unit such as a processor unit (DSP), a host processor etc. in the surveillance camera. After the evaluation, the digital video data with the at least one reference date is converted into analog signals and transmitted to the network unit via an analogue data network. It is also conceivable that the evaluated video data are encoded and / or buffered in a memory unit of the surveillance camera. Before the digital / analog conversion, the stored encoded video data is then decoded again by means of a decoding unit. As a network unit, an image output device, a monitor, a television, a video projector, a mobile image output device, a video data processing device (computer, server, etc.), a network storage device, etc. may be used. The evaluation of the digitally recorded video data can be performed automatically by the camera depending on events, lighting conditions, environmental influences, etc. In this case, a false color display for highlighting certain features, a superimposition of stored video data, an increase in contrast of the video data, etc., can be carried out for the evaluation. Of course, it is also conceivable that the evaluation of the digitally recorded video data is triggered due to manually entered commands or additional information. Such commands or additional information can be transmitted from a computer, a server, a database, etc. via, for example, a packet-switched communication network to the surveillance camera.
Ein wesentlicher Vorteil der Erfindung besteht darin, dass eine digitale Überwachungskamera, die eine Möglichkeit zum zumindest teilweisen Auswerten von digital aufgenommenen Videodaten besitzt, in bestehende analoge Überwachungssysteme integriert werden kann. Somit können analoge Überwachungssysteme einfach, effizient und kosteneffektiv auf veränderte Sicherheits-Anforderungen angepasst werden.A significant advantage of the invention is that a digital surveillance camera, which has a possibility for at least partially evaluating digitally recorded video data, can be integrated into existing analog monitoring systems. Thus, analog monitoring systems can be easily, efficiently and cost-effectively adapted to changing security requirements.

Die Verarbeitungseinheit VE der erfindungsgemässen Überwachungskamera SC kann verschiedene Bildverarbeitungsalgorithmen bzw. Auswertmethodiken ausführen. Selbstverständlich ist es auch denkbar, dass die für die Auswertung benötigten Algorithmen über zum Beispiel dem paketvermittelnden Kommunikationsnetzes heruntergeladen werden können. Dies vereinfacht die Wartung und die Aktualisierung der erfindungsgemässen Überwachungskamera. So kann z.B. eine Sabotagedetektion bzw.
