Description

Die Erfindung des Hauptpatentes beschreibt eine Scanner-Anordnung, bei der große Objekte wie z.B. Autos, Lkws, Busse und Züge auf ihrer Unterseite mit hoher Bildqualität optisch erfaßt werden können, und dabei die Anordnung der optischen und elektronischen Erfassungskomponenten so gewählt wird, daß für den Einbau nur geringfügige Baumaßnahmen notwendig sind und gleichzeitig eine einfache Wartung möglich ist.The Invention of the main patent describes a scanner assembly, in the great Objects such as Cars, trucks, buses and trains on their bottom with high picture quality optically detected can be and the arrangement of the optical and electronic detection components so chosen that for the installation only minor construction work are necessary and at the same time easy maintenance is possible.

Die Erfindung des Zusatzpatentes hat weitere Verbesserungen der erfindungsgemäßen Lösung des Hauptpatentes besonders zur Bilderfassung und Bildauswertung zum Inhalt.The Invention of the additional patent has further improvements of the invention of the solution Main patent especially for image acquisition and image analysis for Content.

Für die vorliegende Erfindung waren die Patentschriften DE 44 11 994 A1 und USP 4,630,109 hinsichtlich ihrer technischen Inhalte und vorgesehenen Anwendungen für die vorliegende erfinderische Lösung zu berücksichtigen. So wird in der DE 44 11 994 A1 die Detektion und Klassifizierung von Fahrzeugen für die Verkehrsüberwachung und Verkehrskontrolle des laufenden Verkehrs als Aufgabe der Erfindung benannt, dazu erfolgt die Bestimmung der Geschwindigkeit durch Laserradar und die Erfassung der Konturen der Fahrzeuge über ein 3D Bildaufnahmeverfahren.The patents were for the present invention DE 44 11 994 A1 and USP 4,630,109 for their technical contents and intended applications for the present inventive solution. So will in the DE 44 11 994 A1 the detection and classification of vehicles for traffic monitoring and traffic control of current traffic named as an object of the invention, this is done to determine the speed by laser radar and the detection of the contours of the vehicles via a 3D image recording method.

Im USP 4,630,109 wird eine Sensoranordnung beschrieben, die den seitlichen Abstand eines Fahrzeuges aus dem Fahrzeug bestimmt und mit diesen gemessenen Werten über eine entsprechende Elektronik Einfluß auf die Steuerung des Fahrzeuges nimmt. Unter Beachtung der in der DE 44 11 994 A1 und USP 4,630,109 dargelegten technischen Lösungen für die Erfassung der Geschwindigkeit wird für die Unterstützung des Korrelationsverfahrens nach dem Hauptpatent DE 100 38 731 B4 vorgeschlagen, eine zusätzliche Einrichtung zur Erfassung der Geschwindigkeit und/oder Position der Fahrzeuge im Detektionsbereich anzuordnen.In USP 4,630,109 a sensor arrangement is described, which determines the lateral distance of a vehicle from the vehicle and with these measured values via a corresponding electronics influence on the control of the vehicle. In compliance with the in the DE 44 11 994 A1 and USP 4,630,109, for the detection of speed, is for supporting the correlation method after the main patent DE 100 38 731 B4 proposed to arrange an additional means for detecting the speed and / or position of the vehicles in the detection area.

Diese zusätzliche Einrichtung hat die weitere Verbesserung der erfindungsgemäßen Lösung des Hauptpatentes besonders zur Bilderfassung und Bildauswertung zum Inhalt. Diese Verbesserungen der erfindungsgemäßen Lösung betreffen im Einzelnen:
Zur Unterstützung des Korrelationsverfahrens wird im Zusatzpatent Akz. 101 34 975.0 vorgeschlagen, eine zusätzliche Einrichtung zur Erfassung der Geschwindigkeit und/oder Position der Fahrzeuge im Detektionsbereich anzuordnen.This additional device has the further improvement of the inventive solution of the main patent especially for image acquisition and image analysis to the content. These improvements of the solution according to the invention relate in more detail to:
In support of the correlation procedure, the additional patent Akz. 101 34 975.0 proposed to arrange an additional means for detecting the speed and / or position of the vehicles in the detection area.

Für die beiden Kameras A und B mit ihren Strahlen 4A und 4B werden bei Erfordernis getrennte Schlitze in der Fahrbahn zur Erfassung und Aufnahme der Fahrzeugunterböden angeordnet. Bei großen Objekten kann eine dritte Kamera oder können weitere Kameras zur Aufteilung des Betrachtungsfeldes angeordnet werden.For both Cameras A and B with their beams 4A and 4B are required separate slots in the roadway for detecting and recording the Vehicle subfloors arranged. For large objects can a third camera or can more cameras arranged to divide the field of view become.

Diese Einrichtung selbst besteht aus Komponenten des Standes der Technik für derartige Funktionen.These The device itself consists of components of the prior art for such Functions.

Aufgabe der nachfolgenden Erfindung ist es, eine weitere technische Möglichkeit für die Erfassung der Geschwindigkeit und oder Position der Fahrzeuge im Detektionsbereich zu schaffen, wenn aus verschiedenen Gründen die technische Lösung des Zusatzpatentes Akz. 101 34 975.0 A1 nicht realisiert werden kann. Ein solcher Fall liegt vor, wenn es aus baulichen Gründen nicht möglich ist, einen zweiten Schlitz in der Fahrbahn zu realisieren oder der Abstand der Schlitze zwischen der eigentlichen Bildaufnahmekamera und der Korrelationskamera nicht genügend groß ist.task The following invention is another technical possibility for the Recording the speed and or position of the vehicles in the Detection area to create, if for various reasons the technical solution of the additional patent Akz. 101 34 975.0 A1 can not be realized can. Such a case exists if it is not for structural reasons possible is to realize a second slot in the roadway or the Distance of the slots between the actual imaging camera and the correlation camera is not big enough.

Für diesen Fall wird vorgeschlagen eine zusätzliche Zeilen- oder Flächenkamera seitlich der abzuscannenden Fahrzeuge, horizontal in der Höhe des Schlitzes für die Scanstrahl und vertikal in geeigneter Höhe anzuordnen. Aus den Bildern dieser Kamera wird die Winkelgeschwindigkeit des vorbeifahrenden Fahrzeuges ermittelt und mit Hilfe des Bildes der Scankamera wird der Abstand zum Fahrzeug bestimmt. Aus den beiden Meßwerten wird die lineare Geschwindigkeit des Fahrzeuges beim Überfahren des Schlitzes dann errechnet.For this Case is proposed an additional Line or area camera at the side of the vehicles to be scanned, horizontally at the height of the slot for the Scan beam and vertically at a suitable height to arrange. From the pictures This camera will monitor the angular velocity of the passing Vehicle is determined and with the help of the image of the scan camera the distance to the vehicle determined. From the two measured values is the linear velocity of the vehicle when crossing the Slot then calculated.

In der 1 ist die erfindungsgemäße Lösung schematisch dargestellt.In the 1 the solution according to the invention is shown schematically.
