Die Offenlegungsschrift EP 0 925 679 A1 zeigt eine Vorrichtung zur digitalen Erfassung von transparenten Dokumentenvorlagen.The disclosure document EP 0 925 679 A1 shows a device for digitally capturing transparent document templates.

Die Patentschrift US 5,890,305 zeigt eine Vorrichtung zum Prüfen von Dokumenten im Durchlicht. Dabei wird die Hintergrundbeleuchtung mit Hilfe einer Flüssigkristallschicht auf die Größe der Dokumente maskiert.The patent specification U.S. 5,890,305 shows a device for checking documents in transmitted light. The background lighting is masked to the size of the documents with the help of a liquid crystal layer.

Zur Überprüfung der Echtheit von Dokumenten wie beispielsweise Reisepässen oder Personalausweisen werden in verschiedenen Anwendungen, wie etwa bei der Grenzkontrolle im Rahmen der First-Line-Inspektionen, üblicherweise Ganzseiten-Dokumentenprüfgeräte verwendet, welche mit optischen Bildkameras bestückt sind.To check the authenticity of documents such as passports or ID cards, full-page document checking devices that are equipped with optical cameras are usually used in various applications, such as in border controls as part of first-line inspections.

Eine Bildkamera eines derartigen Dokumentenlesegerätes ist üblicherweise in einem Kameraraum untergebracht, welcher mit einer transparenten Dokumentenauflage, meist aus transparentem Glas, abgedeckt ist. Das zu erfassende Dokument wird auf die Dokumentenauflage aufgelegt und aus dem Kameraraum heraus mit Licht in verschiedenen Wellenbereichen, etwa Weißlicht, UV-A oder nahes IR, beleuchtet. Das reflektierte Licht wird mittels der Bildkamera als Auflichtbild optisch erfasst und anschließend ausgewertet.An image camera of such a document reading device is usually accommodated in a camera room which is covered with a transparent document overlay, usually made of transparent glass. The document to be captured is placed on the document support and illuminated from the camera room with light in different wavelength ranges, such as white light, UV-A or near IR. The reflected light is optically captured by the image camera as a reflected light image and then evaluated.

Mit konventionellen Dokumentenprüfgeräten können jedoch nicht sämtliche Sicherheitsmerkmale von Dokumenten überprüft werden. Aus diesem Grund werden weiterführende, forensische Überprüfungen von Dokumenten üblicherweise in Prüflaboren von qualifiziertem Personal durchgeführt. Hierbei können beispielswiese Wasserzeichen optisch überprüft werden. Eine weiterführende Überprüfung der Echtheit von Dokumenten ist jedoch teuer und zeitaufwendig und bedarf eines qualifizierten Personals.However, not all security features of documents can be checked with conventional document checking devices. For this reason, further, forensic examinations of documents are usually carried out in test laboratories carried out by qualified personnel. Here, for example, watermarks can be visually checked. However, further verification of the authenticity of documents is expensive and time-consuming and requires qualified personnel.

Es ist daher die Aufgabe der vorliegenden Erfindung, ein effizienteres Dokumentenprüfgerät bereitzustellen, das weiterführende Dokumentenprüfungen, ggf. auch für First-Line-Inspektionen, ermöglicht.It is therefore the object of the present invention to provide a more efficient document checking device that enables further document checks, possibly also for first-line inspections.

Auf diese Weise können auch bestehende Dokumentenprüfgeräte um eine Durchlichtfunktonalität erweitert werden, mit der innere Strukturen von Dokumenten, beispielsweise Wasserzeichen oder Sicherheitsfäden, mittels eines Dokumentenlesegerätes automatisch inspiziert werden können. Die zusätzliche Beleuchtungseinheit kann in vielen Fällen auch nachgerüstet werden, so dass auch bestehende Dokumentenprüfgeräte kosteneffizient um eine zusätzliche Prüffunktionalität erweitert werden können.The invention is based on the finding that the above object can be achieved by providing an additional lighting unit in a cover of the document bed Document checking device can be solved efficiently. In this way, existing document checking devices can also be expanded to include transmitted light functionality, with which the inner structures of documents, for example watermarks or security threads, can be inspected automatically using a document reading device. In many cases, the additional lighting unit can also be retrofitted, so that existing document verification devices can also be cost-effectively expanded to include additional verification functionality.

Mit dem Begriff der Lichttransparenz ist vorliegend eine zumindest bereichsweise und/oder zeitweise Lichttransparenz zu verstehen.In the present case, the term light transparency is to be understood as meaning light transparency at least in regions and/or at times.

Mit dem Begriff der Lichtintransparenz ist vorliegend eine geringere Lichttransparenz als die der lichttransparenten Dokumentenauflage zu verstehen. Die Lichtintransparenz der lichtintransparenten Abdeckung kann zumindest bereichsweise und/oder zeitweise vorliegen.In the present case, the concept of light opacity is to be understood as meaning a lower level of light transparency than that of the light-transparent document support. The light opaqueness of the light opaque cover can be present at least in regions and/or at times.

Das Durchleuchten des Dokumentes bei der Dokumentenprüfung ermöglicht die Prüfung von inneren Sicherheitsmerkmalen eines Dokumentes, beispielsweise Wasserzeichen, metallischen Strukturen wie Metallfäden oder sonstigen eingebetteten Strukturen, welche mittels einer konventionellen Bilderfassung auf der Basis eines reflektierten oder remittierten Lichts nicht ohne Weiteres sichtbar gemacht werden können.X-raying the document during the document check enables the check of internal security features of a document, for example watermarks, metallic structures such as metal threads or other embedded structures, which cannot easily be made visible using conventional image acquisition based on reflected or remitted light.

Die lichttransparente Dokumentenauflage kann beispielswese aus Glas gefertigt sein. Die Dokumentenauflage ist seitlich an dem Dokumentenprüfgerät Dokumentenprüfgerät angeordnet. Dabei ist die lichtintransparente Abdeckung ebenfalls seitlich am Dokumentenprüfgerät angeordnet und es ist vorgesehen, das Dokument federnd gegen die Dokumentenauflage zu pressen. Auf diese Weise können unterschiedliche Dicken und/oder Größen von Dokumenten, beispielsweise ID-1, ID-2 oder Pässe mit unterschiedlich vielen Visa-Seiten, ausgeglichen werden.The light-transparent document support can be made of glass, for example. The document support is arranged on the side of the document checking device document checking device. The non-transparent cover is also on the side Arranged document checking device and it is intended to resiliently press the document against the document support. In this way, different thicknesses and/or sizes of documents, for example ID-1, ID-2 or passports with different numbers of visa pages, can be compensated.

Bei einer Auflage des Dokumentes an bzw. auf der lichttransparenten Dokumentenauflage ist eine Rückseite des Dokumentes der lichttransparenten Dokumentenauflage abgewandt und der lichtintransparenten Abdeckung zugewandt. Durch die Beleuchtungseinrichtung wird die Rückseite des Dokumentes angestrahlt, wodurch das Dokument in Richtung der lichttransparenten Dokumentenauflage durchleuchtet wird. Das dabei entstehende Durchleuchtbild kann beispielsweise durch eine Bildkamera, welche in einem Kameraraum hinter der lichttransparenten Dokumentenauflage angeordnet sein kann, optisch erfasst und mittels eines Prozessors ausgewertet werden.When the document is placed on or on the light-transparent document support, a rear side of the document faces away from the light-transparent document support and faces the light-intransparent cover. The back of the document is illuminated by the lighting device, as a result of which the document is transilluminated in the direction of the light-transparent document bed. The resulting X-ray image can be optically recorded, for example, by an image camera, which can be arranged in a camera room behind the light-transparent document bed, and evaluated by a processor.

Das Dokument kann eines der folgenden Dokumente sein: Wertdokument, insbesondere eine Banknote, Identitätsdokument, wie Personalausweis, Reisepass, Zugangskontrollausweis, Berechtigungsausweis, Unternehmensausweis, Steuerzeichen oder Ticket, Geburtsurkunde, Führerschein oder Kraftfahrzeugausweis, Zahlungsmittel, beispielsweise eine Bankkarte oder Kreditkarte. Das Dokument kann ein- oder mehrlagig bzw. papier- und/oder kunststoffbasiert sein. Das Dokument kann aus kunststoffbasierten Folien aufgebaut sein, welche zu einem Körper mittels Verkleben und/oder Laminieren zusammengefügt werden, wobei die Folien bevorzugt ähnliche stoffliche Eigenschaften aufweisen.The document can be one of the following documents: document of value, in particular a bank note, identity document such as an identity card, passport, access control card, authorization card, company ID card, tax stamp or ticket, birth certificate, driver’s license or vehicle registration card, means of payment, for example a bank card or credit card. The document can have one or more layers or be based on paper and/or plastic. The document can be made up of plastic-based foils, which are joined together to form a body by means of gluing and/or laminating, with the foils preferably having similar material properties.

Gemäß einer Ausführungsform ist die Beleuchtungseinrichtung ausgebildet, Weißlicht, Ultraviolettlicht und/oder Infrarotlicht auszusenden.According to one embodiment, the lighting device is designed to emit white light, ultraviolet light and/or infrared light.

Gemäß einer Ausführungsform ist die Beleuchtungseinrichtung an oder in einer der lichttransparenten Dokumentenauflage zuwendbaren Abdeckungsseite der lichtintransparenten Abdeckung angeordnet. Dadurch wird erreicht, dass das Licht in Richtung der lichttransparenten Dokumentenauflage ausgesendet wird. Durch die lichtintransparente Abdeckung wird gleichzeitig ein Störlichteinfall auf die lichttransparente Dokumentenauflage verhindert.According to one embodiment, the lighting device is arranged on or in a cover side of the light-intransparent cover that can be turned toward the light-transparent document bed. This ensures that the light is emitted in the direction of the light-transparent document support. At the same time, the opaque cover prevents stray light from falling on the translucent document support.

Gemäß einer Ausführungsform ist die Beleuchtungseinrichtung ausgebildet, unterschiedlich große Beleuchtungsbereiche zu erzeugen, um unterschiedlich große Dokumente zu durchleuchten. Hierzu kann die Beleuchtungseinrichtung mehrere Lichtelemente aufweisen, beispielsweise LEDs, welche flächig angeordnet sind und einzeln ansteuerbare oder einschaltbare Lichtbereiche bilden.According to one embodiment, the illumination device is designed to generate illumination areas of different sizes in order to x-ray documents of different sizes. For this purpose, the lighting device can have a plurality of light elements, for example LEDs, which are arranged over a large area and form light areas that can be controlled or switched on individually.

Gemäß einer Ausführungsform weist die Beleuchtungseinrichtung eine Mehrzahl von schaltbaren Lichtelementen, insbesondere Licht emittierenden Dioden, auf, um unterschiedlich große Beleuchtungsbereiche zur Durchleuchtung von unterschiedlich großen Dokumenten zu erzeugen. Die Beleuchtungsbereiche sind festgelegt durch eine Größe eines leuchtenden Bereichs der Beleuchtungseinrichtung. Die Größe eines leuchtenden Bereichs kann beispielsweise durch eine Anzahl der aktivierten, d.h. eingeschalteten und flächig angeordneten Lichtelemente festgelegt sein.According to one embodiment, the illumination device has a plurality of switchable light elements, in particular light-emitting diodes, in order to generate illumination areas of different sizes for x-raying documents of different sizes. The illumination areas are defined by a size of a luminous area of the illumination device. The size of a luminous area can be determined, for example, by a number of activated, i.e. switched on and arranged over a large area light elements.

Gemäß einer Ausführungsform weist die Beleuchtungseinrichtung erste Lichtelemente, welche einen ersten Beleuchtungsbereich festlegen, und zweite Lichtelemente, welche einen zweiten Beleuchtungsbereich festlegen, auf, wobei die ersten Lichtelemente für die Durchleuchtung eines Dokumentes mit einer ersten Größe aktivierbar sind und wobei die ersten Lichtelemente und die zweiten Lichtelemente für die Durchleuchtung eines Dokumentes mit einer zweiten Größe aktivierbar sind, oder wobei die zweiten Lichtelemente für die Durchleuchtung eines Dokumentes mit der ersten Größe deaktivierbar sind.According to one embodiment, the lighting device has first light elements, which define a first lighting area, and second light elements, which define a second lighting area, wherein the first light elements can be activated for the X-raying of a document with a first size and wherein the first light elements and the second Light elements can be activated for x-raying a document of a second size, or the second light elements can be deactivated for x-raying a document of the first size.

Die zweiten Lichtelemente können zusätzlich zu den ersten Lichtelementen hinzugeschaltet werden. Hierbei kann die Größe des Dokumentes beispielsweise mittels einer Benutzerschnittstelle, beispielsweise einer graphischen Benutzerschnittstelle oder eines Schalters auswählbar sein. Die Größe des Dokumentes kann jedoch automatisch erkannt werden. Hierzu kann mittels einer Bildkamera des Dokumentenprüfgerätes eine Kalibrierungsaufnahme des Dokumentes erzeugt werden. Auf der Basis der Kalibrierungsaufnahme kann beispielsweise mittels einer Kantendetektion eine Kontur und somit eine Größe des Identifikationselementes bestimmt werden.The second light elements can be switched on in addition to the first light elements. In this case, the size of the document can be selectable, for example, by means of a user interface, for example a graphical user interface or a switch. However, the size of the document can be detected automatically. For this purpose, a calibration recording of the document can be generated using an image camera of the document checking device. On the basis of the calibration recording, a contour and thus a size of the identification element can be determined, for example by means of edge detection.

Gemäß einer Ausführungsform umgibt der zweite Beleuchtungsbereich den ersten Beleuchtungsbereich zumindest teilweise oder der zweite Beleuchtungsbereich grenzt an den ersten Beleuchtungsbereich an. Auf diese Weise können unterschiedlich große Beleuchtungsbereiche für die Durchleuchtung von unterschiedlich großen Dokumenten erzeugt werden.According to one embodiment, the second illumination area at least partially surrounds the first illumination area or the second illumination area borders on the first illumination area. In this way, illumination areas of different sizes can be generated for the x-raying of documents of different sizes.

Gemäß einer Ausführungsform umfasst die Beleuchtung mehrere Lichtelemente, die abhängig von Größe und/oder Lage des aufgelegten Dokumentes geschaltet, beispielsweise eingeschaltet oder ausgeschaltet, werden. Hierbei wird beispielsweise zunächst wird ein Auflichtbild erfasst, mittels diesem Größe und Lage des Dokumentes bestimm. In Abhängigkeit von einem Ergebnis dieser Bestimmung könne die entsprechenden Lichtelemente für Durchlicht, die sich hinter dem Dokument befinden, aktiviert werden. Auf diese Weise kann der Beleuchtungsbereich für die Durchleuchtung von unterschiedlich großen Dokumenten in verschiedenen Auflagepositionen erzeugt werden.According to one embodiment, the lighting comprises a plurality of light elements which are switched, for example switched on or off, depending on the size and/or position of the document placed. In this case, for example, a reflected light image is first recorded, by means of which the size and position of the document are determined. Depending on a result of this determination, the corresponding light elements for transmitted light, which are located behind the document, can be activated. In this way, the illumination area for x-raying documents of different sizes can be generated in different support positions.

Erfindungsgemäß weist die lichttransparente Dokumentenauflage eine bereichsweise änderbare Lichttransparenz auf. Dadurch wird erreicht, dass die Dokumentenauflage bereichsweise abgedunkelt werden kann, um zu verhindern, dass auf die Dokumentenauflage einfallendes Fremdlicht in einen ggf. unterhalb oder hinter der Dokumentenauflage liegenden Kameraraum mit einer Bildkamera gelangen kann. Derjenige Dokumentenauflagebereich, welcher durch das Dokument abdeckbar ist, wird hingegen nicht abgedunkelt bzw. wird auf lichttransparent geschaltet, um eine optische Aufnahme des Dokumentes mittels der Bildkamera zu ermöglichen.According to the invention, the light-transparent document support has a light transparency that can be changed in certain areas. The result of this is that the document bed can be darkened in certain areas in order to prevent extraneous light falling on the document bed from being able to get into a camera room with an image camera that may be located below or behind the document bed. In contrast, that document support area which can be covered by the document is not darkened or is switched to light-transparent in order to enable an optical recording of the document by means of the video camera.

Gemäß einer Ausführungsform ist ein erster Dokumentenauflagebereich der lichttransparenten Dokumentenauflage durch das Dokument abdeckbar, wobei ein zweiter Dokumentenauflagebereich der lichttransparenten Dokumentenauflage außerhalb des ersten Dokumentenauflagebereichs angeordnet ist, und wobei eine Lichttransparenz des ersten Dokumentenauflagebereichs höher als eine Lichttransparenz des zweiten Dokumentenauflagebereichs einstellbar oder anwählbar ist. Die Einstellung der Lichttransparenz kann durch einen Prozessor, beispielswese den hier beschriebenen Prozessor, vorgenommen werden. Durch die Verringerung der Lichttransparenz des zweiten Dokumentenauflagebereichs wird dieser abgedunkelt. Andererseits wird der erste, transparente Dokumentenauflagenbereich durch das Dokument abgedeckt. Somit kann durch die Dokumentenauflage hindurch kein Fremdlicht in einen darunter oder dahinter liegenden bzw. durch die Dokumentenauflage abgedeckten Kameraraum eindringen.According to one embodiment, a first document support area of the light-transparent document support area can be covered by the document, with a second document support area of the light-transparent document support area being arranged outside of the first document support area, and wherein a light transparency of the first document support area can be set or selected to be higher than a light transparency of the second document support area. The light transparency can be adjusted by a processor, for example the processor described here. By reducing the light transparency of the second document support area, it is darkened. On the other hand, he will first, transparent document overlay area covered by the document. Thus, no extraneous light can penetrate through the document support into a camera space located below or behind it or covered by the document support.

Erfindungsgemäß weist die lichttransparente Dokumentenauflage Flüssigkristallzellen auf, welche zur bereichsweisen Änderung der Lichttransparenz der lichttransparenten Dokumentenauflage bereichsweise ansteuerbar sind, oder die lichttransparente Dokumentenauflage umfasst eine Flüssigkristallschicht, insbesondere eine Folie, wobei die Flüssigkristallschicht Flüssigkristallzellen aufweist, welche zur bereichsweisen Änderung der Lichttransparenz der lichttransparenten Dokumentenauflage bereichsweise ansteuerbar, beispielsweise mit elektrischer Spannung beaufschlagbar, sind. Die Ansteuerung kann mittels eines Prozessors, beispielswese mittels des hier beschriebenen Prozessors, erfolgen.According to the invention, the light-transparent document overlay has liquid crystal cells which can be controlled in areas for changing the light transparency of the light-transparent document overlay in areas, or the light-transparent document overlay comprises a liquid crystal layer, in particular a film, the liquid crystal layer having liquid crystal cells which can be activated in areas for changing the light transparency of the light-transparent document overlay in areas , For example, can be subjected to electrical voltage. The control can take place by means of a processor, for example by means of the processor described here.

In beiden Fällen können die Flüssigkristallzellen zu einer Matrix angeordnet und bereichswiese dem ersten Dokumentenauflagebereich oder dem zweiten Dokumentenauflagebereich, beispielsweise durch eine Adressierung, zugeordnet werden. Zu Beginn der optischen Erfassung ist die gesamte Dokumentenauflage beispielsweise lichttransparent. Dadurch wird die optische Erfassung des ersten Dokumentenauflagenbereichs ermöglicht. Diese kann beispielswese mittels einer Detektion, beispielsweise mittels des hier beschriebenen Prozessors, einer Kontur des Dokumentes auf der Dokumentenauflage durchgeführt werden. Danach wird der durch das Dokument nicht abgedeckte zweite Dokumentenauflagenbereich beispielsweise mittels des hier beschriebenen Prozessors intransparent geschaltet bzw. abgedunkelt. Nach der Abdunkelung kann das Dokument optisch, beispielsweise mittels einer unterhalb der Dokumentenauflage angeordneten optischen Kamera, erfasst werden.In both cases, the liquid crystal cells can be arranged in a matrix and assigned in certain areas to the first document support area or to the second document support area, for example by addressing. At the beginning of the optical detection, the entire document overlay is light-transparent, for example. This enables the optical detection of the first document support area. This can be carried out, for example, by means of a detection, for example by means of the processor described here, of a contour of the document on the document support. The second document support area not covered by the document is then switched to be non-transparent or darkened, for example by means of the processor described here. After it has been darkened, the document can be captured optically, for example by means of an optical camera arranged below the document bed.

Gemäß einer Ausführungsform ist der Prozessor ausgebildet, den ersten Dokumentenauflagebereich anhand einer optischen Erfassung des Dokumentes zu bestimmen. Auf diese Weise kann die geometrische Ausdehnung bzw. Position des ersten Dokumentenauflagebereichs in Abhängigkeit von einer Größe und/oder einem Auflageort des auf die Dokumentenauflage auflegbaren Dokumentes bestimmt werden.According to one embodiment, the processor is designed to determine the first document support area based on an optical detection of the document. In this way, the geometric extent or position of the first document support area can be determined as a function of a size and/or a support location of the document that can be placed on the document support.

Die optische Erfassung des Dokumentes kann beispielsweise ausgehend von einer anfangs transparenten Dokumentenauflage mittels einer optischen Kamera des Dokumentenlesegerätes erzeugt werden, welche durch den Prozessor ausgewertet wird, um darin das Dokument bzw. dessen Lage auf der Dokumentenauflage zu detektieren. Diese Detektion kann mittels einer Kantenerkennung oder einer Mustererkennung durchgeführt werden. Nach der Detektion kann der Prozessor die Dokumentenauflage außerhalb des ersten Dokumentenauflagebereichs abdunkeln bzw. intransparent schalten.The optical detection of the document can be generated, for example, starting from an initially transparent document overlay by means of an optical camera of the document reading device, which is evaluated by the processor in order to detect the document or its position on the document overlay. This detection can be carried out using edge detection or pattern detection. After the detection, the processor can darken or switch the document bed to non-transparent outside of the first document bed area.

Dadurch wird eine Anpassung einer Größe des ersten Dokumentenauflagebereichs an unterschiedliche Größen von Dokumenten erreicht. Der erste Dokumentenauflagebereich kann beispielsweise lichttransparent geschaltet werden oder lichttransparent bleiben, während der zweite Dokumentenauflagebereich, welcher den ersten Dokumentenauflagebereich zumindest teilweise umgibt und nicht durch das Dokument abgedeckt ist, abgedunkelt bzw. auf nicht-transparent geschaltet werden kann. Dadurch wird effizient einem Streulichteinfall entgegengewirkt.This allows the size of the first document support area to be adapted to different sizes of documents. The first document support area can, for example, be switched to be light-transparent or remain light-transparent, while the second document support area, which at least partially surrounds the first document support area and is not covered by the document, can be darkened or switched to non-transparent. This efficiently counteracts the incidence of scattered light.

Gemäß einer Ausführungsform ist der erste Dokumentenauflagebereich in Abhängigkeit von einer Größe des Dokumentes vorgebbar, insbesondere mittels einer graphischen Benutzerschnittstelle auswählbar oder eingebbar. Hierbei können beispielsweise verschiedene Größen von Dokumenten auswählbar bzw. eingebbar sein, um die Größe des ersten, lichttransparenten Dokumentenauflagebereichs zu bestimmen. Der zweite Dokumentenauflagebereich, welcher den ersten Dokumentenauflagebereich zumindest teilweise umgibt bzw. außerhalb des ersten Dokumentenauflagebereichs liegt, ist beispielsweise der restliche Bereich der Dokumentenauflage und kann beispielswiese für die optische Aufnahme des Dokumentes abgedunkelt bzw. auf intransparent geschaltet werden.According to one embodiment, the first document support area can be specified as a function of the size of the document, in particular can be selected or entered using a graphical user interface. Here, for example, different sizes of documents can be selected or entered in order to determine the size of the first, light-transparent document support area. The second document bed area, which at least partially surrounds the first document bed area or is outside the first document bed area, is, for example, the remaining area of the document bed and can be darkened or switched to opaque for the optical recording of the document.

Gemäß einer Ausführungsform weist das Dokumentenprüfgerät einen Kameraraum, welcher durch die lichttransparente Dokumentenauflage abgedeckt ist, und eine in dem Kameraraum angeordnete Bildkamera für die Aufnahme eines Durchleuchtbildes des Dokumentes auf.According to one embodiment, the document checking device has a camera space, which is covered by the light-transparent document overlay, and an image camera arranged in the camera space for recording a transmitted image of the document.

Gemäß einer Ausführungsform kann in dem Kameraraum eine weitere Beleuchtungseinrichtung angeordnet sein, um das Dokument auf der lichttransparenten Auflage zu beleuchten. Dadurch kann die Bildkamera das Auflichtbild des Dokumentes für eine weitere Dokumentenprüfung optisch erfassen. Die weitere Beleuchtungseinrichtung kann ausgebildet sein, Weißlicht, Infrarotlicht oder Ultraviolettlicht zu erzeugen.According to one embodiment, a further lighting device can be arranged in the camera space in order to illuminate the document on the light-transparent support. In this way, the camera can optically record the reflected light image of the document for a further document check. The additional lighting device can be designed to generate white light, infrared light or ultraviolet light.

Erfindungsgemäß weist das Dokumentenprüfgerät ein Gehäuse auf, wobei die lichtintransparente Abdeckung an dem Gehäuse schwenkbar angeordnet ist. Die lichtintransparente Abdeckung kann beispielswese als eine schwenkbare Federklappe gebildet sein.According to the invention, the document checking device has a housing, with the light-opaque cover being pivotably arranged on the housing. The cover, which is opaque to light, can be formed, for example, as a pivotable spring flap.

Erfindungsgemäß weist die lichtintransparente Abdeckung ein erstes lichtintransparentes Abdeckelement und ein zweites lichtintransparentes Abdeckelement auf, wobei das erste lichtintransparente Abdeckelement an dem Gehäuse schwenkbar befestigt ist und wobei das zweite lichtintransparente Abdeckelement an dem ersten lichtintransparenten Abdeckelement federnd befestigt ist. Die lichtintransparente Abdeckung ist somit zweigeteilt.According to the invention, the opaque cover has a first opaque cover element and a second opaque cover element, the first opaque cover element being pivotably attached to the housing and the second opaque cover element being resiliently attached to the first opaque cover element. The non-transparent cover is thus divided into two.

Durch das zweite lichtintransparente Abdeckelement kann ein konstanter Anpressdruck auf das Dokument erzeugt werden. Dadurch kann das Dokument auch auf einer seitlich liegenden Dokumentenauflage, deren Flächennormale beispielsweise im Rahmen eines Toleranzbereichs senkrecht auf einen Schwerkraftvektor steht, gegen die Schwerkraft gehalten werden. Durch das Anpressen wird darüber hinaus erreicht, dass unerwünschtes Streulicht von außen unterbunden wird, wodurch eine definierte Durchleuchtbeleuchtung realisiert werden kann.A constant contact pressure can be generated on the document by the second opaque cover element. As a result, the document can also be held against the force of gravity on a laterally lying document support whose surface normal is, for example, within a tolerance range perpendicular to a gravity vector. The pressing effect is also achieved in that unwanted scattered light from the outside is suppressed, as a result of which a defined backlighting can be implemented.

Gemäß einer Ausführungsform weist das Dokumentenprüfgerät einen Prozessor zur Steuerung der Beleuchtungseinrichtung oder zur Steuerung einer Lichttransparenz der lichttransparenten Dokumentenauflage auf. Der Prozessor kann der vorstehend oder nachstehend beschriebene Prozessor sein.According to one embodiment, the document checking device has a processor for controlling the lighting device or for controlling a light transparency of the light-transparent document overlay. The processor may be the processor described above or below.

Gemäß einer Ausführungsform ist das Dokument durchleuchtbar, um ein Durchleuchtbild zu erhalten, und wobei der Prozessor ausgebildet ist, das Durchleuchtbild zu verarbeiten, um einen Durchleuchtbildbereich zu erhalten, welcher einer Größe des Dokumentes entspricht. Das Durchleuchtbild kann mittels der Bildkamera erfasst werden. Die Verarbeitung kann beispielsweise ein Software-realisiertes Zuschneiden, sog. Clipping, des Durchleuchtbildes umfassen.According to one embodiment, the document can be X-rayed in order to obtain a X-ray image, and the processor is designed to process the X-ray image in order to obtain a X-ray image area which is a size of the document is equivalent to. The X-ray image can be captured by the image camera. The processing can include, for example, software-implemented cropping, so-called clipping, of the X-ray image.

Gemäß einer Ausführungsform ist das Dokument durchleuchtbar, um ein Durchleuchtbild zu erhalten, und wobei der Prozessor ausgebildet ist, das Durchleuchtbild mit einem Referenzbild zu vergleichen, um das Dokument zu prüfen. Das Durchleuchtbild kann beispielsweise mittels der Bildkamera erfasst werden.According to one embodiment, the document can be X-rayed in order to obtain a X-ray image, and the processor is designed to compare the X-ray image with a reference image in order to examine the document. The X-ray image can be captured by the image camera, for example.

Gemäß einer Ausführungsform ist das Dokument eines der folgenden Dokumente: ein Ausweisdokument, ein Reisepass, ein Zahlungsmittel, eine Bankkarte, eine Kreditkarte, ein Führerschein, ein Unternehmensausweis, ein Frachtbrief oder ein Berechtigungsausweis. Im Allgemeinen kann das Dokument auch jedes andere Dokument sein, dessen Identität und Echtheit bestätigt werden soll. Das Dokument kann einen integrierten Schaltkreis enthalten.According to one embodiment, the document is one of the following documents: an identification document, a passport, a means of payment, a bank card, a credit card, a driver's license, a company ID card, a bill of lading or an authorization card. In general, the document can also be any other document whose identity and authenticity is to be confirmed. The document may contain an integrated circuit.

Die Erfindung betrifft ferner ein Verfahren zum Prüfen eines Dokumentes, mit: Beleuchten einer Rückseite eines auf einer lichttransparenten Dokumentenauflage eines Dokumentenprüfgerätes mit einer Vorderseite aufliegenden Dokumentes, um das Dokument zu durchleuchten; und Aufnehmen eines Durchleuchtbildes des Dokumentes.The invention also relates to a method for checking a document, comprising: illuminating a back side of a document lying on a light-transparent document support of a document checking device with a front side in order to x-ray the document; and capturing a candling image of the document.

Die Prüfung des Dokumentes kann auf der Basis des Durchleuchtbildes, beispielsweise durch einen Vergleich des Durchleuchtbildes mit einem Referenzbild, vorgenommen werden. Hierzu kann das Dokumentenprüfgerät eine Datenbank mit Referenzbildern umfassen. Gemäß einer Ausführungsform umfasst das Dokumentenprüfgerät eine Kommunikationsschnittstelle für die Kommunikation mit einem externen Datenserver, welcher Referenzbilder bereitstellt, über ein Kommunikationsnetzwerk.The document can be checked on the basis of the X-ray image, for example by comparing the X-ray image with a reference image. For this purpose, the document checking device can include a database with reference images. According to one embodiment, the document checking device comprises a communication interface for communication with an external data server, which provides reference images, via a communication network.

Weitere Merkmale des Verfahrens zum Prüfen eines Dokumentes ergeben sich unmittelbar aus der Funktionalität des Dokumentenprüfgerätes.Further features of the method for checking a document result directly from the functionality of the document checking device.

Das Verfahren wird erfindungsgemäß mit dem erfindungsgemäßen Dokumentenprüfgerät durchgeführtAccording to the invention, the method is carried out with the document checking device according to the invention

Fig. 1A zeigt eine Draufsicht auf ein Dokumentenprüfgerät 100 mit einer lichttransparenten Dokumentenauflage 101 für die Aufnahme eines in Fig. 1 nicht dargestellten Dokumentes, und mit einer lichtintransparenten Abdeckung 103 zum Abdecken der lichttransparenten Dokumentenauflage 101, wobei die lichtintransparente Abdeckung 103 eine Beleuchtungseinrichtung 105 zum Durchleuchten des Dokumentes aufweist. Figure 1A shows a top view of a document checking device 100 with a light-transparent document support 101 for receiving an in 1 document, not shown, and with a light-opaque cover 103 for covering the light-transparent document overlay 101, the light-opaque cover 103 having an illumination device 105 for transilluminating the document.

Die Beleuchtungseinrichtung 105 umfasst eine Mehrzahl von beispielsweise bereichsweise einschaltbaren Lichtelementen 107. Die Mehrzahl der Lichtelemente 107 umfasst beispielsweise erste Lichtelemente 109, welche einen ersten Beleuchtungsbereich 111 festlegen, und zweite Lichtelemente 113, welche einen zweiten Beleuchtungsbereich 115 festlegen. Die ersten Lichtelemente 109 sind für die Durchleuchtung eines Dokumentes mit einer ersten Größe aktivierbar bzw. einschaltbar und die ersten Lichtelemente 109 und die zweiten Lichtelemente 113 sind gemeinsam für die Durchleuchtung eines größeren Dokumentes mit einer zweiten Größe aktivierbar bzw. einschaltbar. Alternativ können die zweiten Lichtelemente 113 für die Durchleuchtung eines Dokumentes mit der ersten Größe deaktiviert werden. Das Dokumentenprüfgerät 100 weist ferner ein Gehäuse 116 mit einem Kameraraum 117 auf, welcher durch die lichttransparente Dokumentenauflage 101 abgedeckt ist. Ferner umfasst das Gehäuse 116 eine in dem Kameraraum 117 angeordnete Bildkamera 119 für die Aufnahme eines Durchleuchtbildes des Dokumentes.The lighting device 105 includes a plurality of light elements 107 that can be switched on in certain areas, for example. The first light elements 109 can be activated or switched on for x-raying a document of a first size, and the first light elements 109 and the second light elements 113 can be activated or switched on together for x-raying a larger document of a second size. Alternatively, the second light elements 113 can be deactivated for the X-raying of a document with the first size. The document checking device 100 also has a housing 116 with a camera chamber 117 which is covered by the light-transparent document support 101 . Further the housing 116 includes an image camera 119 arranged in the camera space 117 for recording a X-ray image of the document.

Die lichtintransparente Abdeckung 103 ist an dem Gehäuse 116, beispielsweise mittels eines oder mehrerer Scharniere 131, schwenkbar angeordnet.The opaque cover 103 is pivotally mounted on the housing 116, for example by means of one or more hinges 131.

Die lichtintransparente Abdeckung 103 umfasst ein erstes lichtintransparentes Abdeckelement 121 und ein zweites lichtintransparentes Abdeckelement 123. Das erste lichtintransparente Abdeckelement 121 ist an dem Gehäuse 116 schwenkbar befestigt. Das zweite lichtintransparente Abdeckelement 123 ist an dem ersten lichtintransparenten Abdeckelement 121 federnd befestigt. Das zweite lichtintransparente Abdeckelement 123 kann als eine gefederte Andruckspange ausgebildet sein. Auf diese Weise kann das Dokument federnd gegen die lichttransparente Dokumentenauflage 101 gepresst werden.The opaque cover 103 comprises a first opaque cover element 121 and a second opaque cover element 123. The first opaque cover element 121 is attached to the housing 116 in a pivotable manner. The second opaque cover element 123 is resiliently fastened to the first opaque cover element 121 . The second opaque cover element 123 can be designed as a spring-loaded pressure clip. In this way, the document can be resiliently pressed against the light-transparent document bed 101 .

Die lichttransparente Dokumentenauflage 101 ist seitlich am Gehäuse 116 an einer Gehäuseseite 125 angeordnet. Das Gehäuse umfasst ferner eine Gehäuseoberschale 127.The light-transparent document support 101 is arranged laterally on the housing 116 on a housing side 125 . The housing also includes a housing upper shell 127.

Die lichtintransparente Abdeckung 103, welche auch einen beweglichen Tisch formt, ist gemäß einer Ausführungsform gegenüber der Gehäuseoberschale 127 abgesenkt angeordnet. Dadurch wird ermöglicht, beispielsweise Dokumentenseiten eines Reisepasses bei abgeklappten Buchdeckeln einzulegen bzw. auf die Dokumentenauflage 101 aufzulegen.According to one embodiment, the opaque cover 103, which also forms a movable table, is arranged lowered in relation to the upper housing shell 127.
