Description

Vorrichtung zum Erkennen und Analysieren eines aus Farben im Spektral- und Infrarot-Wellenbereich bestehenden Sicherheitszeichens Device for detecting and analyzing a security mark consisting of colors in the spectral and infrared waveband
Die Erfindung betrifft eine Vorrichtung zum Auslesen und Analysieren eines Sicherheitszeichens, mit einem Farbbildsensor und einer Beleuchtung im Rahmen eines Rücknahmeautomaten für Einwegverpackungen, wie PET-Flaschen und dergleichen, welche ein derartiges Sicherheitszeichen als Etikett tragen.The invention relates to a device for reading and analyzing a security sign, with a color image sensor and a lighting in the context of a reverse vending machine for disposable packaging, such as PET bottles and the like, which carry such a safety mark as a label.
Im allgemeinen Stand der Technik sind Schwarz- /Weiß-Bildverarbeitungssensoren mit angeschlossenen Rechnern zur Bildverarbeitung hinlänglich bekannt.In the general state of the art, black and white image processing sensors with connected computers for image processing are well known.
Diese weisen aber gewisse Nachteile auf und zwar in der Art, dass z.B. Fälschungen bei denen statt der Infrarotfarbe eine hellblaue Farbe appliziert wird, also nicht dem Original entsprechend, trotzdem als richtig erkannt werden. Dadurch lässt sich, ein Sicherheitszeichen sogar mit normalen Farbdruckern reproduzieren. Weil solche Sicherheitszeichen für Pfand- Gelderstattung auf Einwegverpackungen benutzt werden, kann es zu erheblichen Geldverlusten kommen, was erfindungsgemäß vermieden wird.However, these have certain disadvantages in the way that e.g. Forgeries in which instead of the infrared color a light blue color is applied, thus not according to the original, nevertheless recognized as correct. This makes it possible to reproduce a safety mark even with normal color printers. Because such safety signs are used for deposit-refund on disposable packaging, it can lead to significant losses of money, which is inventively avoided.
Dabei stellt sich für einen schwarz /weiß Bildsensor das Hellblau als grau dar. Wenn nun die originale Infrarotfarbe grau ist oder der Untergrund auf dem die graue Infrarotfarbe appliziert wird ebenfalls grau ist, dann kann der schwarz-/ weiß Bildsensor keinen signifikanten Unterschied zwischen dem Original und der Fälschung feststellen; dadurch erfüllt das System mit einem schwarz-/ weiß Bildsensor nicht vollends seine Aufgabe. Diese Unsicherheit führt auch dazu, dass schlechte Leserergebnisse die Folge dieses Nachteiles sind.The light blue turns out to be gray for a black and white image sensor. If the original infrared color is gray or the background on which the gray infrared color is applied is also gray, then the black and white image sensor can not make a significant difference between the original and the gray and the forgery; As a result, the system does not completely fulfill its task with a black and white image sensor. This uncertainty also leads to poor reader results being the result of this disadvantage.
Erfindungsgemäß wird die Aufgabenstellung einer falschungssicheren Analyse eines Sicherheitszeichens durch die Merkmale von Anspruch 1 gelöst. Die nachfolgenden abhängigen Ansprüche geben vorteilhafte Weiterbildungen der Erfindung wieder.According to the invention, the task of a falsification-proof analysis of a security sign is achieved by the features of claim 1. The following dependent claims give advantageous developments of the invention.
Mit dem Farbbildsensor und in Verbindung mit einer weißen oder gemischten blaugrünen Beleuchtung sowie der Benutzung eines Rotsperrfilters weist die Vorrichtung alle bildartigen Darstellungen die unter Kunstlicht nicht grau sind, bei der Analyse mit einer Beleuchtung im spektralen Wellenbereich von weiß oder blaugrün zurück, weil für den Farbbildsensor das zu erkennende Zeichen nicht grau ist. Unter Infrarotlicht prüft der .Farbbildsensor, ob der Bereich der bildartigen Darstellung, der aus Infrarotfarbe besteht sich nun genau gegensätzlich verhält wie unter Kunstlicht, indem schwarz transparent wird oder transparent schwarz wird. Durch eine besondere Farbe oder ein Markierungsfeld die/das sich im oder am Rande der bildlichen Darstellung befindet kann mit Hilfe dieses Zusatzzeichens der Befehl an die Bildverarbeitungssoftware gegeben werden, dass der Untergrund auf dem sich das mit Infrarotfarbe applizierte Zeichen befindet nicht weiß ist sondern einen anderen spektralen Wert besitzt. Diesen Unterschied kann ein schwarz /weiß Bildsensor des Standes der Technik dagegen nicht differenzieren.With the color image sensor and in conjunction with a white or mixed blue-green illumination and the use of a red blocking filter, the device has all the image-like Representations that are not gray under artificial light, when analyzed with backlighting in the spectral wave range of white or blue-green, because for the color image sensor, the character to be recognized is not gray. Under infrared light, the color image sensor checks whether the region of the image-like representation which consists of infrared color behaves exactly opposite to that under artificial light in that black becomes transparent or becomes transparent black. By means of a special color or a marking field which is located in or on the edge of the pictorial representation, the command to the image processing software can be given with the help of this additional sign that the background on which the infrared-applied character is located is not white but a different one has spectral value. By contrast, a black and white image sensor of the prior art can not differentiate this difference.
Ein weiterer Vorteil dieser erfindungsgemäßen Vorrichtung ist, dass nur ein Bild und nicht wie bei herkömmlicher Bildverarbeitungssensoren und ihren verbundenen Rechnern, für eine Analyse zwei Bilder gemacht werden müssen und zwar eines im spektralen Lichtbereich und das andere unter IR-Licht.A further advantage of this device according to the invention is that only one image and not, as in conventional image processing sensors and their associated computers, two images must be taken for analysis, one in the spectral light region and the other under IR light.
Bei der erfindungsgemäßen Vorrichtung sind die LED 's der Beleuchtungseinheit im Spektral- irαd Infrarot- Wellenbereich gleichzeitig aktiv geschaltet, während bei herkömmlichen Lesesystem jeweils die verschiedenen Beleuchtungen im Wechsel aktiviert werden. Dabei wird errlndungsgemäß eine Koordinatenmatrix erstellt. Jedes dadurch entstehende Feld wird im fortlaufenden Wechsel zum einen für das Registrieren im spektralen Wellenbereich reserviert und zum anderen für das Registrieren der Darstellung unter infrarotem Licht reserviert, dadurch ist erfmdungsgemäß bedingt, dass nur ein Bild gemacht wird, obwohl aber tatsächlich zwei unterschiedliche Bilder in einer Bildaufhahme erstellt werden. Dadurch ergibt sich erfindungsgemäß, dass ein Teil des Bildes den spektralen Wellenbereich darstellt und der andere den infraroten Wellenbereich.In the device according to the invention, the LEDs of the illumination unit in the spectral irαd infrared wave range are simultaneously activated, whereas in conventional reading systems the different lights are activated alternately. According to the invention, a coordinate matrix is created. Each resulting field is reserved in the continuous change to the one for the registration in the spectral wave range and reserved for the other to register the representation under infrared light, thereby according to the invention requires that only one image is taken, but in fact two different images in one Image capture will be created. This results according to the invention in that one part of the image represents the spectral waveband and the other the infrared waveband.
Daraus ergibt sich der weitere erfindungsgemäße Vorteil, dass das Fälschungsrisiko reduziert wird, weil genau geprüft wird, dass es sich tatsächlich um ausschließlich ein homogenes Bild handelt und nicht um zwei Bilder die nebeneinander gestellt die bildartige Darstellung zum einen wie der Bildsensor es unter spektralen Licht und zum anderen unter Infrarotlicht sehen würde. Die Erfindung wird nachfolgend exemplarisch anhand eines Ausführungsbeispiels näher beschrieben. Es zeigt:This results in the further inventive advantage that the risk of counterfeiting is reduced, because it is precisely checked that it is actually only a homogeneous image and not two images juxtaposed the image-like representation on the one hand as the image sensor under spectral light and to see another under infrared light would. The invention will now be described by way of example with reference to an embodiment. It shows:

In Prozess (9) Fig. 2 werden die gefundenen Grauwerte/ Pixel mit den Sollwerten verglichen ebenso die IR-Farben Pixel werden unter IR-Licht geprüft und mit den Sollwerten verglichen. In Prozess (10) Fig. 2 wird geprüft ob die Graupixel sich in den vorgegebenen Koordinatenfeldern befinden. Dieser Prozess findet unter spektralem und infrarotem Licht statt. Stimmen die Ist- mit den Sollwerten nicht überein erfolgt im Prozess (10 + 11) Fig. 2 die Ergebnisanalyse „falsch", das Ergebnis wird an den externen Rechner (8) Fig. 2 weitergeleitet, der wiederum die Abweisung veranlasst. Der Leseprozess wird in Prozess (12) Fig. 2 damit beendet.If a positive preliminary result is created in process (5), FIG. 2, the center of the image found is determined in process (S), and the geometric properties are checked.
