Definitions

  • the invention relates to a method for detecting and checking the authenticity of banknotes with an electromagnetic radiation source, and a device for detecting and checking the authenticity of banknotes, in which the banknote is emitted into an electromagnetic radiation source, e.g. Light source is inserted.
  • an electromagnetic radiation source e.g. Light source
  • banknotes are illuminated in incident light, for example with an ultraviolet light source, in order to enable visual control in this way are known.
  • the evaluation is based on the experience of the viewer, depending on the banknote, the focus being on specific, characteristic positions of the banknote suitable for the evaluation.
  • a number of devices are known for the automatic evaluation of banknotes, in which the banknotes are passed under a scanner.
  • the special evaluation detects a number of criteria oriented towards a specific bank note and is carried out according to a predetermined scheme, so that a separate presetting is required for each bank note.
  • Such devices can generally only be used for a small number of different banknotes if the effort for the evaluation should not be too high.
  • the invention now aims to provide a method and a device of the type mentioned at the beginning with which a simple adaptation of the recognition to different banknotes is facilitated.
  • the invention aims to minimize the detection effort via simple procedures that can be carried out without complex computers so that a rapid and reliable evaluation of a large number of each other is possible different banknotes is possible.
  • the method according to the invention is used to achieve this object. Ren for recognizing and checking the authenticity of banknotes essentially characterized in that a black and white image of the irradiated banknote is recorded and that the image is an evaluation of the number, frequency and / or area distribution of at least 32 detected gray levels will throw.
  • the device according to the invention for recognizing and checking the authenticity of banknotes in which the banknote is inserted into an electromagnetic radiation source such as a light source, is essentially characterized in that the banknote is guided between a digital camera and a light source and it is detected that the video signal of the image camera is fed to a computer, that at least 32 gray levels in their relative arrangement, frequency and / or area share in the image are subjected to an evaluation and that an evaluation signal for the authenticity of a display and / or Control for the forwarding of the banknote is fed.
  • a still image By capturing a banknote carried between a digital camera and a light source, a still image can be are taken, the video signal of the image camera possibly being subjected to a conventional data compression, in particular an image data compression, before further processing.
  • the signals to be evaluated in the sequence should contain at least 32 gray levels on the recording side, the video signal being able to be subjected to a corresponding computing operation which can increase the significance of the subsequent evaluation with a correspondingly reduced computing effort.
  • the evaluation of the number of gray levels can also take place on the basis of compressed signals, it also being possible to subsequently further evaluate correspondingly coded signals, such as sum signals of the individual pixel information.
  • an evaluation signal for the authenticity of a display can be obtained in a very short time and / or a controller for forwarding the banknote.
  • the design is advantageously made such that the banknote is kept at a standstill on an illuminated plate during the recording.
  • Such a still picture allows any compression and coding before further processing, the reproducibility being independent of the transport speed of the feed or other mechanical parameters in any case.
  • the evaluation comprising at least 64, preferably 128 gray levels, the gray level signal advantageously being compared with reference signals in order to quickly follow appropriate results.
  • the reference signals can either be supplied externally to the respective computer in the form of data.
  • the design can advantageously be made such that the computer has an adaptive learning circuit, in particular an iteration circuit for calibration to a specific bank note, which enables reference signals to be formed by iteration.
  • the design can advantageously be such that a difference signal between the image signal and the reference signal is fed to the evaluation circuit.
  • the design is such that the electromagnetic steel source is designed as a steel source with short-wave light, UV or X-ray source, which ensures that even with relatively densely printed banknotes there is a maximum of evaluable signals.
  • the design preferably being such that the black and white image of the banknote is used for a picture element evaluation e.g. is subject to a "pattern recognition".
  • image evaluation programs are used, for example, in connection with the evaluation of satellite images, in which case a high degree of error tolerance is also achieved, since incorrectly read data or disturbances in the image can possibly be compensated for.
  • a banknote 1 can be seen on a transparent support 2, the banknote being held at a standstill by a digital camera 3 during the photographic recording.
  • the banknote 1 is emitted via a radiation source 4 designed as a light source shines through.
  • the signal from the digital camera passes via data lines 5 and a data compressor or data concentrator 6 to a computer 7, in which the corresponding evaluation takes place.
  • the digital camera 3 is to record at least 32 gray levels, and when the evaluation confirms the authenticity, a corresponding signal 8 can be actuated to display the authenticity.
  • a corresponding lock or a further transport mechanism can also be actuated in order to enable the banknote recognized as genuine to be stored in a corresponding slot for receiving this banknote.
  • the light source can be adapted to the particular type of bank notes 1 to be examined. In principle, high-energy, electromagnetic radiation sources are particularly advantageous for densely printed banknotes.
  • the digital camera 3 is intended to enable at least 5 band images per second with the desired resolution for rapid and reliable detection.
  • the transparent plate 2 can also be replaced by a perforated plate, and can in particular ensure the secure standstill position for fixing the banknotes during the recording by sucking in air through corresponding holes in the plate.

Abstract

En vue de la détection et de la vérification de l'authenticité de billets de banque (1), ceux-ci sont traversés par un rayon lumineux provenant d'une source lumineuse (4), et une image en noir et blanc avec au moins 32 niveaux de gris détectés est prise par une caméra numérique (3). Le signal de la caméra numérique (3) est envoyé à un ordinateur (7) pour l'évaluation du nombre, de la fréquence et/ou de la distribution en surface des niveaux de gris détectés.
