Embodiment 1

[0018] figure 1 It is a flow chart of a banknote authenticating method provided in Embodiment 1 of the present invention. The method is suitable for counterfeiting banknotes. The method can be implemented by a banknote counterfeiting device. The device can be implemented by software and / or hardware, and is generally integrated into a banknote detector or an all-in-one deposit and withdrawal machine, etc. in the device. The method specifically includes:

[0019] S110. Obtain an infrared reflection image of the counterfeit banknote to be identified;

[0020] The banknotes to be authenticated are irradiated by an infrared light source, and the image of the banknotes to be authenticated under the irradiation of infrared light is obtained through a sensor located on the same side as the infrared light source. Reflected to the sensor, therefore, the acquired image is the infrared reflectance map. Wherein, the infrared reflection image is a gray scale image.

Embodiment 2

[0034] figure 2 It is a flow chart of a banknote authentication method provided in Embodiment 2 of the present invention. This embodiment is optimized on the basis of the previous embodiment. In this embodiment, the preset characteristic areas include preset non-discoloration areas and The preset discoloration area is for "determining the corresponding feature area in the infrared reflection image according to the preset feature area of ​​the real currency corresponding to the counterfeit banknote to be identified" and "determining the feature area of ​​the feature area according to the pixel value". Display features" and "authenticating the counterfeit banknotes to be authenticated according to the display features" are further optimized, specifically including the following steps:

[0035] S210. Obtain an infrared reflection image of the counterfeit banknote to be identified;

[0036] S220. Determine a corresponding non-discoloration area in the feature area according to t...

Embodiment 3

[0052] Figure 4 It is a schematic diagram of a banknote authenticating device provided in Embodiment 3 of the present invention, specifically including:

[0053] Infrared reflectance map acquisition module 410, used to obtain the infrared reflectance map of banknotes to be authenticated;

[0054] The feature area determination module 420 is used to determine the corresponding feature area in the infrared reflection image according to the preset feature area of ​​the genuine currency corresponding to the counterfeit banknote to be identified;

[0055] A pixel value acquisition module 430, configured to acquire pixel values ​​of pixels in the feature region;

[0056] A display characteristic determining module 440, configured to determine the display characteristic of the characteristic region according to the pixel value;

[0057] The banknote authenticating module 450 is used for authenticating the banknotes to be authenticated according to the display features.

Abstract

The embodiments of the invention disclose a banknote authenticity identification method and apparatus. The method comprises the following steps: obtaining an infrared reflectogram of a banknote to be authenticated; according to a preset feature area of a true banknote corresponding to the banknote to be authenticated, determining a corresponding feature area in the infrared reflectogram; obtaining a pixel value of a pixel point in the feature area; according to the pixel value, determining a display feature of the feature area; and according to the display feature, performing authentication on the banknote to be authenticated. According to the embodiments of the invention, through identifying the display feature of each corresponding feature area corresponding in the infrared reflectogram of the banknote to be authenticated, the banknote to be authenticated is authenticated, the problem of non-ideal authentication result in the prior art is solved, and the accuracy of a banknote authentication result is improved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of banknote inspection, and in particular to a method and device for authenticating banknotes. Background technique [0002] The existence and spread of counterfeit money have brought adverse effects on people's lives, and even threatened the safe operation of the financial industry, interfering with the normal economic order of the country. [0003] The commonly used method is to use the anti-counterfeiting characteristics under visible light or ultraviolet light to authenticate banknotes, such as using banknote size, watermark, security thread or fluorescent characteristics to detect the authenticity of banknotes. [0004] However, when the devices corresponding to these methods are integrated into financial equipment, using these methods to inspect banknotes often has the problem of unstable detection characteristics. Sometimes even genuine coins cannot detect accurate results, r...
