Abstract
Verfahren zur Erfassung der Beleuchtungssituation an Verkehrswegen, welche mit an Straßenlaternen angebrachten Beleuchtungskörpern (6) beleuchtet werden, wobei die Messung von einem Fahrzeug aus erfolgt und die Leuchtdichte und/oder die Beleuchtungsstärke hinter einer hinsichtlich Ihrer spektralen und absoluten Durchlässigkeit definiert lichtdurchlässigen Scheibe (5) gemessen wird und zusätzlich die geometrische Form der Beleuchtungskörper (6) erfasst wird, indem eine Messung mit zwei Kameras (3.1, 3.2) durchgeführt wird, welche um drei Achsen gedreht werden können und in Richtung der Straßenlaternen (6) ausgerichtet werden, so dass aus den Winkeln zwischen den Zielrichtungen der Kameras (3.1, 3.2) und/oder der Größe der Abbildungen auch der Abstand zu den Beleuchtungskörpern (6) bestimmt werden kann, wobei die Kameras (3.1, 3.2) im Sättigungsbereich ihres lichtempfindlichen Sensors betrieben und die Form der Beleuchtungskörper aus den abgebildeten Umrisskanten ermittelt wird.Method for detecting the lighting situation on traffic routes, which are illuminated with lighting fixtures (6) mounted on street lamps, wherein the measurement takes place from a vehicle and the luminance and / or the illuminance behind a translucent pane (5) defined with respect to its spectral and absolute permeability In addition, the geometric shape of the lighting fixtures (6) is detected by performing a measurement with two cameras (3.1, 3.2) which can be rotated about three axes and aligned in the direction of the street lamps (6), so that off the angles between the target directions of the cameras (3.1, 3.2) and / or the size of the images and the distance to the lighting fixtures (6) can be determined, the cameras (3.1, 3.2) operated in the saturation region of its photosensitive sensor and the shape of the Lighting fixture determined from the contour outline shown becomes.
Description
Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur Erfassung der Beleuchtungssituation an Verkehrswegen.The invention relates to a method and a device for detecting the lighting situation on traffic routes.
Die Erfindung ist insbesondere für selektive Beleuchtungsmessungen an Verkehrswegen einsetzbar und ermöglicht die Überprüfung der Beleuchtungssituation sowie der Funktionstüchtigkeit und der Wirksamkeit von Straßenbeleuchtungen.The invention can be used in particular for selective illumination measurements on traffic routes and makes it possible to check the lighting situation as well as the functionality and efficiency of street lighting.
Zur Beurteilung der Beleuchtung von Fahrbahnen ist es bekannt, die auf der Fahrbahn vorhandene Bestrahlungsstärke zu messen, um eine Information zu den Sichtbedingungen für Verkehrsteilnehmer zu gewinnen.In order to assess the illumination of lanes, it is known to measure the irradiance present on the road in order to obtain information on the visibility conditions for road users.
Aus dem Stand der Technik sind zur Bestimmung der Beleuchtungssituation auf Fahrbahnen verschiedene Verfahren und Anordnungen bekannt.Various methods and arrangements are known from the prior art for determining the lighting situation on roadways.

Um Aussagen über den Beleuchtungszustand zu gewinnen, können die bekannten Methoden zwar auch angewendet werden. Nachteilig ist dabei jedoch, dass der von der Beschaffenheit des Straßenbelags abhängige Reflexionsfaktor das Ergebnis beeinflusst, und somit keine eindeutige Aussage über die Parameter und den Zustande der Straßenbeleuchtungseinrichtungen ermöglicht.In order to gain information about the illumination state, the known methods can indeed be applied. The disadvantage here, however, that the dependent on the nature of the road surface reflection factor affects the result, and thus no clear statement about the parameters and the state of the street lighting devices allows.
Aus
Diese Anordnung ermöglicht es, die Beleuchtungssituation auf der Fahrbahn zu erfassen. Sie ist zur Erkennung einer Landebahnbefeuerung vorgesehen und erfasst die Beleuchtungsverhältnisse beim Überfahren der Feuer. Dabei wird jeweils genau ein Beleuchtungsköper erfasst. Die Erfassung von Beleuchtungskörper, die in unterschiedlicher Höhe angebracht sind, sowie Aussagen über die Art und die Lage der Beleuchtungskörper können damit nicht ermittelt werden.This arrangement makes it possible to detect the lighting situation on the road. It is designed to detect a runway lighting and detects the lighting conditions when driving over the fire. In each case exactly one light fixture is detected. The detection of lighting fixtures that are mounted at different heights, as well as statements about the type and location of lighting fixtures can not be determined.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren und eine Anordnung der eingangs genannten Art zu schaffen, welche eine Aussage über den Zustand von Fahrbahnbeleuchtungseinrichtungen ermöglichen, die weitgehend unabhängig von störenden Einflüssen ist.The invention has for its object to provide a method and an arrangement of the type mentioned above, which allow a statement about the condition of roadway lighting devices, which is largely independent of disturbing influences.
Erfindungsgemäß wird die Aufgabe mit einem Verfahren, welches die in Anspruch 1 angegebenen Merkmale aufweist, und mit einer Vorrichtung, welche die in Anspruch 3 angegebenen Merkmale enthält, gelöst.According to the invention the object is achieved with a method which has the features specified in claim 1, and with a device which contains the features specified in claim 3.
Vorteilhafte Ausgestaltungen sind in den Unteransprüchen angegeben.Advantageous embodiments are specified in the subclaims.
Die Erfindung ermöglicht es, die Art der Beleuchtungskörper sowie Ihre Anzahl und deren Funktion zu ermittelt.The invention makes it possible to determine the type of lighting fixtures as well as their number and their function.
Die erfindungsgemäße Vorrichtung ist vorzugsweise auf einem geeigneten beweglichen System angeordnet, welches die geographische Lage mit einem GPS-System bestimmen kann. Die Vorrichtung enthält ein Kamerasystem, das aus zwei Kameras besteht, die in Richtung der Beleuchtungskörper ausgerichtet sind. Die Kameras werden im Sättigungsbereich ihrer lichtempfindlichen Sensoren betrieben, um die Form der Beleuchtungskörper aus deren Umrisskanten ermitteln zu können.The device according to the invention is preferably arranged on a suitable mobile system which can determine the geographical position with a GPS system. The device includes a camera system consisting of two cameras aligned in the direction of the lighting fixtures. The cameras are operated in the saturation region of their photosensitive sensors in order to determine the shape of the lighting fixtures from their outline edges.
Hinter einer definiert lichtdurchlässige Fläche, die in Ihrer spektralen und absoluten Durchlässigkeit an die jeweilige Applikation angepasst ist, ist ein Leuchtdichtesensor angeordnet.Behind a defined translucent surface, which is adapted in its spectral and absolute permeability to the respective application, a luminance sensor is arranged.
Die erfindungsgemäße Anordnung ermöglicht es, die vorhandene Anzahl von Beleuchtungskörpern, ihre Funktionstüchtigkeit, ihre Leuchtdichte sowie die Beleuchtungssituation auf der Fahrbahn zu erfassen und eine Auswertung unter Berücksichtigung von geographischen Daten zu erstellen.The inventive arrangement makes it possible to detect the existing number of lighting fixtures, their functionality, their luminance and the lighting situation on the road and to create an evaluation in consideration of geographical data.
Die Erfindung wird im Folgenden anhand eines Ausführungsbeispieles näher erläutert. In der zugehörigen Zeichnung ist in
Auf einem Verkehrsweg
Auf dem Fahrzeug
Damit ist es möglich, dass die Messanordnung erkennt, ob die Beleuchtung von Na-Dampflampen oder von Hg-Dampflampen oder von Mischsituationen erfolgt.It is thus possible for the measuring arrangement to detect whether the illumination of Na vapor lamps or of Hg vapor lamps or of mixed situations takes place.
Durch Vergleich mit in einem Speicher hinterlegten Sollwerten können auch Fehler, beispielsweise defekte Lampen, erkannt werden.By comparison with stored in a memory setpoints and errors, such as defective lamps can be detected.
