Abstract

The embodiment of the invention discloses a recognition method of a transversely spliced banknote. The method comprises a step of obtaining the infrared transmission image of a banknote to be identified and determining the longitudinal edge position of an anti-fake metal wire according to the pixel gray scale distribution characteristic in the infrared transmission image, and a step of obtaining the column projection of the longitudinal edge position of the anti-fake metal wire in the infrared transmission image of the banknote to be identified and judging whether the banknote is the transversely spliced banknote according to the projection intensity of the column projection. By using the technical scheme provided by the embodiment of the invention, a transversely spliced fake banknote can be effectively identified, and the identification effect is stable.

Description

technical field [0001] The invention relates to the field of banknote detection, in particular to a method and device for identifying horizontally spliced ​​banknotes. Background technique [0002] In recent years, there has been a phenomenon of spliced ​​banknotes circulating in the market. The spliced ​​banknotes refer to uncovering the front or back of the banknotes, and forging the banknotes by means of cutting, piecing together, altering and the like. At present, there are two main types of "spliced ​​banknotes" that are more common: one is to divide a real coin into two, and at the same time put half of the real coin and half of the counterfeit together by pasting; Cut out the coins, and paste the color-changing fluorescent numbers on the cut out genuine coins on the same position of the counterfeit coins with large denominations, so as to make the counterfeit ones real. [0003] In the existing methods for identifying the authenticity of banknotes, it is relatively ...
