Abstract
Description
Die Erfindung betrifft ein Verfahren zur Verkehrszeichenerkennung, bei dem ein oder mehrere Verkehrszeichen und/oder zumindest ein dem oder den Verkehrszeichen zugeordnetes Zusatzzeichen erfasst werden.The The invention relates to a method for traffic sign recognition, in which one or more traffic signs and / or at least one of the or the traffic signs associated additional characters are detected.
Aus
der
Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren zur Verkehrszeichenerkennung anzugeben, mittels welchem insbesondere eine Erfassung von Zusatzzeichen verbessert und somit eine zuverlässige Ausgabe einer korrekten Bedeutung des Verkehrzeichens und dessen Zusatzzeichens erreicht wird.Of the Invention is based on the object, a method for traffic sign recognition specify, by means of which in particular a detection of additional characters improved and thus a reliable output of a correct Meaning of the traffic sign and its additional sign achieved becomes.
Die Aufgabe wird erfindungsgemäß mit einem Verfahren gelöst, welches die im Anspruch 1 angegebenen Merkmale aufweist.The Object is according to the invention with a method solved, which specified in claim 1 features having.
Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.advantageous Embodiments of the invention are the subject of the dependent claims.
Das erfindungsgemäße Verfahren zur Verkehrszeichenerkennung, bei dem ein oder mehrere Verkehrszeichen und/oder zumindest ein dem oder den Verkehrszeichen zugeordnetes Zusatzzeichen erfasst werden, zeichnet sich erfindungsgemäß dadurch aus, dass das Zusatzzeichen nach der Erfassung des Verkehrszeichens mittels zumindest eines Suchalgorithmus in vorgegebenen Positionen bezüglich einer Position des Verkehrszeichens gesucht wird.The inventive method for traffic sign recognition, in which one or more traffic signs and / or at least one the additional character associated with the traffic sign or signs be distinguished according to the invention thereby from that the additional sign after the detection of the traffic sign by means of at least one search algorithm in predetermined positions is searched for a position of the traffic sign.
Bei diesen vorgegebenen Positionen handelt es sich insbesondere um gesetzlich vorgeschriebene Positionen und/oder um häufig verwendete Positionen, welche beispielsweise in Fahrversuchen ermittelt wurden. Somit ist es in vorteilhafter Weise möglich, den Verkehrszeichen zugeordnete Zusatzzeichen zuverlässig und schnell zu erkennen und somit die Wirkung von Fahrerassistenzsystemen eines Fahrzeuges zu verbessern. Bei den Fahrerassistenzsystemen kann es sich beispielsweise um eine automatische Unterstützung eines Fahrers des Fahrzeuges bei der Einhaltung einer aktuellen Geschwindigkeitsbegrenzung auf einem augenblicklich befahrenen Straßenabschnitt (auch als Intelligent Speed Adaption bekannt) handeln.at these given positions are in particular legal prescribed positions and / or frequently used Positions that were determined, for example, in driving tests. Thus, it is possible in an advantageous manner, the traffic signs assigned additional characters reliably and quickly recognize and thus the effect of driver assistance systems of a vehicle to improve. In the driver assistance systems, for example for automatic assistance of a driver of the vehicle when complying with a current speed limit an immediately traveled section of road (also as Intelligent Speed Adaptation) act.
