Embodiment 1

[0050] figure 1 It is a flow chart of a method for identifying the authenticity of banknotes provided by Embodiment 1 of the present invention. This embodiment is applicable to the situation where the cash deposit and withdrawal machine is used to identify the authenticity of deposited banknotes. The method can be used to identify the authenticity of banknotes The device is implemented, and the device can be realized by hardware and / or software, and the method for identifying the authenticity of banknotes specifically includes the following steps:

[0051] Step 110: Determine a grayscale reference value according to pixel grayscale values ​​of at least one preset reference area in the banknote to be tested.

[0052] Among them, the preset reference area can be pre-set according to the currency and face value, and one or more preset areas can be selected. The preset reference area can be selected on the front and / or back of the banknote. Usually, there is no ink on the banknote...

Embodiment 2

[0059] figure 2 It is a flow chart of a method for identifying the authenticity of banknotes provided by Embodiment 2 of the present invention. The technical solution of this embodiment is further refined on the basis of the above-mentioned technical solution. The method specifically includes:

[0060] Step 110: Determine a grayscale reference value according to pixel grayscale values ​​of at least one preset reference area in the banknote to be tested.

[0061] Step 120 , calculating the ratio between the pixel gray value of the preset comparison area of ​​the banknote to be tested and the gray reference value.

[0062] Step 140: Determine a template grayscale reference value according to pixel grayscale values ​​of at least one preset template reference area in the template banknote.

[0063] Wherein, the template banknote is a genuine banknote or a counterfeit banknote, and the image of the preset template reference area is acquired by an image sensor, and then the pixel ...

Embodiment 3

[0077] image 3 It is a schematic structural diagram of a device for authenticating banknotes provided by Embodiment 3 of the present invention, and the device can be configured on a cash deposit and withdrawal machine. Such as image 3 As shown, the device 30 for identifying the authenticity of banknotes includes:

[0078] A grayscale reference value determining module 310, configured to determine a grayscale reference value according to the pixel grayscale value of at least one preset reference area in the banknote to be tested;

[0079] Ratio calculation module 320, used to calculate the ratio between the pixel gray value of the preset comparison area of ​​the banknote to be tested and the gray reference value;

[0080] The banknote authenticity determining module 330 is configured to determine the authenticity of the banknote to be tested according to the matching result of the ratio and the preset pixel comparison template.

[0081] Optionally, the preset comparison ar...

Abstract

The embodiment of the invention discloses a method, apparatus and equipment for discriminating authenticity of paper currency, and a storage medium. The method for discriminating authenticity of paper currency includes the steps: according to a pixel gray value of at least one preset reference area of the paper currency to be detected; calculating the ratio between a pixel gray value of the preset comparison area of the paper currency to be detected and the pixel gray value; and according to the coupling result between the ratio and the preset pixel comparison template, determining the authenticity of the paper currency to be detected. The technical scheme of the method, apparatus and equipment for discriminating authenticity of paper currency can determine authenticity of paper currency by obtaining the pixel gray value of the preset comparison area of the paper currency to be detected and performing corresponding data processing, has low requirement for hardware, and is easy to implement.

Description

technical field [0001] The embodiments of the present invention relate to banknote identification technology, and in particular to a method, device, equipment and storage medium for identifying authenticity of banknotes. Background technique [0002] Nowadays, all banks are equipped with all-in-one cash deposit and withdrawal machines. When users perform deposit operations, the all-in-one cash deposit and withdrawal machines need to identify the authenticity of the banknotes deposited. [0003] In the prior art, banknotes are authenticated by identifying special inks used in fixed positions on banknotes, but in general, the printing area of ​​special inks on banknotes is small, which increases the difficulty of obtaining the characteristics of special inks on banknotes On the other hand, the cooperation of ultraviolet light is required to identify special inks, and an ultraviolet light emitting device is added.
