Abstract

The system detects a space-time region using a filtered image sensor (3) in combination with an ultrasonic sensor (2). It automatically detects a change in the region according to a defined tolerance schema and produces a corresp. alarm signal. The plane image sensor image information is expanded to spatial dimensions by the additional application of the ultrasonic sensor or by stereoscopic image acquisition. Several intelligent sensors can be operated and evaluated simultaneously. ADVANTAGE - System enables unambiguous geometric and time characterisation of monitored space or object.

Description

Selbstlernendes Alarmsystem für die Objektüberwa­ chung mit automatischer Objekterkennung über einen kombinierten Ultraschall/Bildsensor.Self-learning alarm system for object monitoring with automatic object recognition via a combined ultrasound / image sensor.

Herkömmliche Alarmsysteme und deren Sensoren erfassen räumliche Geometrien und die zeitliche Änderung derselben bei beobachteten Objekten relativ ungenau. Damit sind eindeutige Identifizierungen und Unter­ scheidungen von Objektänderungen auf Alarmwürdig­ keit äußerst unsicher. Fehlalarme, unbewußt ausgelöst oder bewußt provoziert, sind die Folge.Detect conventional alarm systems and their sensors spatial geometries and the temporal change the same is relatively imprecise for observed objects. This makes unique identifications and sub divorces from object changes to alarm-worthy extremely uncertain. False alarms, triggered unconsciously or deliberately provoked, the result.

Beim Einsatz von Bildsensoren erfolgt eine rein flächi­ ge Auswertung, oder es werden spezielle, teure Bild­ verarbeitungssysteme als Sonderausführungen einge­ setzt, die für den durchschnittlichen Endanwender nicht erschwinglich oder unwirtschaftlich sind. Bei einfachen Systemen erfolgt keine automatische und damit im­ merwährende, reproduzierbare Auswertung des Bildes. Ein menschlicher Beobachter wird meist eingesetzt.When using image sensors, there is a purely flat ge evaluation, or there will be special, expensive picture processing systems as special versions sets that for the average end user not are affordable or uneconomical. With simple Systems is not automatic and therefore in Continuous, reproducible evaluation of the image. A human observer is mostly used.

Die im Hauptanspruch und den Unteransprüchen ange­ gebene Erfindung beseitigt diese Nachteile.The in the main claim and the dependent claims The present invention overcomes these disadvantages.

Ein IR-befilterter Bildaufnehmer, vorzugsweise eine CCD-Flächenkamera liefert ein 2D-Bild zu einem ge­ gebenen Zeitpunkt. Durch Einsatz eines zusätzlichen Ultraschallsensors, der neben dem Bildsensor angeord­ net ist, wird zudem eine räumliche Komponente (z- Achse) gewonnen (Abb. 1). Aufwendiger kann mit Verwendung eines zweiten Bild­ sensors, der in einem horizontalen Abstand zum ersten angeordnet ist, oder über eine ebenso angeordnete Op­ tik, die die unterschiedlichen Bildwinkel auf einen Bildsensor zu unterschiedlichen Zeitpunkten konzen­ triert, und durch entsprechende Auswertung dieser Bildinformationen eine räumliche Komponente gewon­ nen werden.An IR-filtered image recorder, preferably a CCD area camera, delivers a 2D image at a given time. By using an additional ultrasonic sensor, which is arranged next to the image sensor, a spatial component (z-axis) is also obtained ( Fig. 1). More complex can gain a spatial component with the use of a second image sensor, which is arranged at a horizontal distance from the first, or via a likewise arranged optics, which concentrates the different image angles on an image sensor at different times, and by appropriate evaluation of this image information be.

Damit ist eine eindeutige geometrische und zeitliche Charakterisierung des zu überwachenden Rau­ mes/Objektes möglich. Die gewonnene Information wird gelernt, d. h. sie wird als Referenz in einem Spei­ cher (Abb. 2) abgelegt. Gegebenenfalls können mehrere solcher Referenzen eingelesen und abgespeichert wer­ den. Jede Änderung, sei es in der räumlichen Geometrie oder dem zeitlichen Verhalten (z. B: Helligkeitsschwan­ kungen, Bewegung) wird registriert und zur Auswerte­ einheit übertragen. Dazu wird ein spezielles, störunan­ fälliges Protokoll verwendet, um auch den Anschluß mehrerer solcher Sensoren an eine Auswertestation zu ermöglichen. Die Übertragung der Daten vom Sensor zur Auswerteeinheit kann über die Netzleitung, eine Funkstrecke, oder eine separate Verkabelung erfolgen.This enables a clear geometric and temporal characterization of the room / object to be monitored. The information obtained is learned, ie it is stored as a reference in a memory ( Fig. 2). If necessary, several such references can be read in and saved. Every change, be it in the spatial geometry or the temporal behavior (e.g. brightness fluctuations, movement) is registered and transferred to the evaluation unit. For this purpose, a special, fault-prone protocol is used to enable the connection of several such sensors to one evaluation station. The data can be transferred from the sensor to the evaluation unit via the mains cable, a radio link or separate cabling.

Bei Änderung der zeitlichen Bedingungen hinsichtlich von Helligkeitsschwankungen, die vom Sensor regi­ striert werden, kann über einen im Sensor integrierten IR-Sender ein Ausgleich erfolgen. Der Sensor kann da­ bei in seinen Funktionen von der Auswerteeinheit ge­ steuert u. programmiert werden.When changing the time conditions regarding of brightness fluctuations regi can be striated using an integrated sensor IR transmitters are compensated. The sensor is there in its functions from the evaluation unit controls u. be programmed.

Bei Netzausfall dient eine Batteriepufferung im Sensor und der Auswerteeinheit dazu, die Funktion des Sy­ stems sicherzustellen. Die Kamera wird, um die Batte­ rie zu entlasten, nur bei Vorliegen einer Bewegungs­ meldung über den Ultraschallsensor aktiviert.In the event of a power failure, battery backup is used in the sensor and the evaluation unit, the function of the Sy ensure stems. The camera is going to the batte to relieve the strain, only if there is movement message activated via the ultrasonic sensor.

Der Ultraschallsensor kann in seiner Funktion von Be­ wegungsmeldung auf Distanzmessung nach den jewei­ ligen Erfordernissen umgeschaltet werden.The function of the ultrasonic sensor can be from Be Motion report on distance measurement according to the respective current requirements can be switched.
