Embodiment 1

[0057] figure 1 It is a flow chart of a banknote identification method provided by Embodiment 1 of the present invention. The technical solution of this embodiment can be applied to the situation of authenticating banknotes. The method can be executed by a banknote identification device provided in an embodiment of the present invention, which can be implemented in the form of software and / or hardware, and configured and applied in equipment such as banknote validators. The method specifically includes the following operations:

[0058]S110. Acquire a first image of the banknote to be identified under visible light and a second image under infrared light.

[0059] The banknote to be identified may be of any currency, for example, it may be RMB, Singapore currency or Iranian currency. Preferably in RMB. The image of banknotes to be identified under visible light can accurately reflect the position of the anti-counterfeiting pattern. Under infrared light, due to the special...

Embodiment 2

[0066] figure 2 It is a flow chart of a banknote identification method provided by Embodiment 2 of the present invention. On the basis of the above-mentioned embodiments, the embodiment of the present invention further optimizes the method of cutting the second image according to the position of each anti-counterfeit pattern in the first image to obtain the target area corresponding to each anti-counterfeit pattern. operate.

[0067] Correspondingly, the method of this embodiment includes:

[0068] S210. Acquire a first image of the banknote to be identified under visible light and a second image under infrared light.

[0069] S220. According to the first position of all the anti-counterfeit patterns of the banknote to be identified in the first image, cut the first area of ​​all the anti-counterfeit patterns in the first image and the first area of ​​all the anti-counterfeit patterns in the The second region in the second image.

[0070] According to the positions of all...

Embodiment 3

[0080] image 3 It is a flow chart of a banknote identification method provided by Embodiment 3 of the present invention. On the basis of the above embodiments, the embodiment of the present invention further optimizes the anti-counterfeiting pattern to be a serial number, and accordingly optimizes the operation of determining the authenticity of the banknote to be identified according to the target area and the setting rules.

[0081] Correspondingly, the method of this embodiment includes:

[0082] S310. Acquire a first image of the banknote to be identified under visible light and a second image under infrared light.

[0083] S320. According to the position of each anti-counterfeit pattern of the banknote to be identified in the first image, cut the second image to obtain a target area corresponding to each anti-counterfeit pattern.

[0084] S330. Determine that the version of the banknote to be identified is the first version.

[0085] The banknote version to be identif...

Abstract

The invention discloses a banknote discrimination method and apparatus. The method includes acquiring the first image of the banknote to be discriminated in the visible light and the second image of the banknote to be discriminated in the infrared light; cutting the second image to obtain a target area corresponding to each of the anti-counterfeiting patterns according to the position of each anti-counterfeiting pattern of the banknote to be discriminated in the first image; and determining the authenticity of the banknote to be discriminated according to the target area and the setting rule. The banknote discrimination method and apparatus improve the accuracy and speed of banknote authenticity discrimination.

Description

technical field [0001] The embodiments of the present invention relate to banknote processing technology, and in particular to a banknote identification method and device. Background technique [0002] The anti-counterfeiting patterns of banknotes are usually carefully designed. Banknotes of different countries have different anti-counterfeiting designs, and there are many types of anti-counterfeiting patterns. [0003] One of the anti-counterfeiting patterns is the serial number. The serial number is the code printed on the banknote, and each banknote has a unique serial number, so the serial number is widely used in banknote identification. [0004] At present, most identification methods based on the serial number are based on the magnetic detection of the serial number. This method has a poor detection effect on spliced ​​banknotes, so the accuracy of banknote identification is low. Another part of the recognition method based on the serial number is to identify the se...
