Problems solved by technology

[0004] During the circulation of banknotes, the serial number may be unclear due to wear and other reasons
At this time, judging the authenticity of banknotes based on the horizontal serial number is prone to misjudgment, and the banknote recognition rate is low.

Embodiment 1

[0030] This scheme is used to identify banknotes with three serial numbers, such as figure 2 As shown, the three serial numbers are all located on the front, specifically the horizontal serial number and the first vertical serial number recognizable under visible light, the second vertical serial number recognizable under ultraviolet light, the second vertical serial number The serial number is in the same location area as the first vertical serial number. The horizontal serial number is located in the first preset area 0-2 in the lower left corner of the front, and the first vertical serial number and the second vertical serial number are located in the second preset area in the middle of the right side of Chairman Mao's portrait 0-0 0-3. Each of the horizontal serial number, the first vertical serial number and the second vertical serial number consists of two parts: a serial number and a number. Among them, "crown characters" are two or three English letters used to mark...

Embodiment 2

[0051] In the technical solution provided by Embodiment 1, there may be at least two identical serial numbers on the banknotes, but the same serial numbers are false serial numbers. At this time, a missed judgment will occur according to the solution of Embodiment 1.

[0052] Based on this, the embodiment of the present invention also provides a banknote serial number identification method, as a further description of the first embodiment, as Figure 4 As shown, in step 150, before determining that the serial number recognition is successful, it also includes: judging whether the same serial number is true, and now step 150 can be implemented in the following manner:

[0053] Step 151, if at least two of the horizontal serial number, the first vertical serial number and the second vertical serial number are the same, determine whether the same serial number is true. If true, go to step 152, otherwise go to step 153.

[0054] When judging whether the same prefix number is true...

Embodiment 3

[0088] An embodiment of the present invention provides a banknote serial number identification device, the device shown is used to implement the method provided in the above embodiment, the device is located in the banknote identification device, the banknote has a horizontal serial number, a first vertical The serial number and the second vertical serial number, such as Figure 7 shown, including:

[0089] Horizontal serial number identification unit 11, configured to identify the image in the first preset area to obtain the horizontal serial number, where the first preset area is the area where the horizontal serial number is located;

[0090] The first vertical serial number identification unit 12 is used to identify the image in the second preset area to obtain the first vertical serial number, and the second preset area is the first vertical serial number the area in which it is located;

[0091] an irradiation unit 13, configured to apply light of a preset wavelength t...

Abstract

The invention discloses a method and a device for recognizing a crown word number of a banknote. The method comprises the steps of: recognizing an image in a first preset region to obtain a transverse crown word number, wherein the first preset region is the region where the transverse crown word number locates; recognizing an image in a second preset region to obtain a first longitudinal crown word number, wherein the second preset region is the region where the first longitudinal crown word number locates; applying light rays of a preset wavelength to the banknote; recognizing the image in the second preset region under the light rays of the preset wavelength, so as to obtain a second longitudinal crown word number; and determining that crown word number recognition is successful if at least two of the transverse crown word number, the first longitudinal crown word number and the second longitudinal crown word number are identical. When one crown word number of the banknote cannot be recognized or is wrongly recognized, whether the crown word number recognition is successful can be determined through comparing the other two crown word numbers, thereby improving the crown word number recognition efficiency, and enhancing security of the banknote.

Description

technical field [0001] The embodiment of the present invention relates to banknote verification technology, and in particular to a banknote serial number recognition method and device. Background technique [0002] With the gradual increase in the circulation of RMB, the anti-counterfeiting means of RMB have also been strengthened. Because the prefix number can be used as a factor to determine the authenticity of RMB, it is widely used in the scheme of identifying the authenticity of RMB. Each person is uniquely identified by the serial number, and the authenticity of the serial number can be determined by identifying and verifying the identified serial number. [0003] Take the identification of the prefix number of the fifth set of RMB as an example, such as figure 1 As shown, in the present invention, the side printed with Chairman Mao's portrait 0-0 is called the front side, and the other side is called the back side, and the back side is printed with different landsca...
