Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
The scheme is used for identifying paper money with three crown word numbers, as shown in fig. 2, the three crown word numbers are positioned on the front, specifically, a transverse crown word number and a first longitudinal crown word number which can be identified under visible light, and a second longitudinal crown word number which can be identified under ultraviolet light, and the second longitudinal crown word number and the first longitudinal crown word number are positioned in the same position area. The transverse crown word number is located in a first preset area 0-2 at the lower left corner of the front face, and the first longitudinal crown word number and the second longitudinal crown word number are located in a second preset area 0-3 in the middle position of the right side of the chairman portrait 0-0. Each crown word number in the transverse crown word number, the first longitudinal crown word number and the second longitudinal crown word number consists of a crown word and a number. Wherein, the 'crown word' is two or three English letters for marking printing batch, and is arranged and printed by a bank note printer according to a certain rule; the number is an Arabic numeral serial number printed behind the crown word number and used for indicating the arrangement sequence of each banknote in the same crown word number batch.
Fig. 3 is a flowchart of a method for identifying a serial number of a banknote according to an embodiment of the present invention, where the method is applicable to a case where banknotes with multiple serial numbers are identified, and the method may be executed by a banknote identification device, such as an Automatic Teller Machine (ATM), a currency detector, and the like. The method specifically comprises the following steps:
and 110, identifying the image in the first preset area to obtain a transverse crown word number.
Wherein the first preset area is an area where the transverse crown word number is located.
As an example, the rmb with a face value of 100 yuan has a size of 165 × 77mm, and the first predetermined area is a rectangular area composed of (5,15) (45,15) (45,20) (5,20) with 1mm as a coordinate system unit. And scanning the first preset area to obtain an image in the first preset area. And carrying out binarization processing on the image to obtain a binary image. And carrying out image analysis on the binary image to obtain a character string contained in the binary image, wherein the character string is a transverse crown word number.
And 120, identifying the image in the second preset area to obtain a first longitudinal crown word number.
And the second preset area is the area where the first longitudinal crown word number is located.
As an example, the rmb of 100 yuan is 165 × 77mm in size, 1mm is taken as a coordinate system unit, and the second predetermined region is a rectangular region composed of (155,20) (160,20) (160,60) (155, 60). The image recognition method in the second preset area may be implemented by referring to the image recognition method in the first preset area, which is not described herein again.
And step 130, applying light with preset wavelength to the paper money.
The light with the preset wavelength can be ultraviolet light, and the ultraviolet light is a general term of radiation with the wavelength from 10nm to 400nm in an electromagnetic spectrum. As an example uv light corresponds to a wavelength of 200 nm. The image that undergoes a fluorescent reaction with the light of the predetermined wavelength can be obtained by irradiating the bill with ultraviolet rays or the like.
The moving bank note is irradiated by an ultraviolet light source and the fluorescence reflection of the bank note is detected by a silicon photocell, so that the authenticity of the bank note can be judged. In order to eliminate the interference of ambient light on false identification, a set of color filter with the transmission wavelength consistent with the fluorescent reaction wavelength of the counterfeit money can be arranged on the surface of the silicon photocell.
And 140, under the light with the preset wavelength, identifying the image in the second preset area to obtain a second longitudinal crown word number.
If the banknote is true, the second longitudinal crown word number coincides with the first longitudinal crown word number. The first longitudinal crown number may be acquired under visible light (e.g., light provided by fluorescent lights). A second longitudinal crown number is available under uv light. The process of identifying the image in the second preset area to obtain the second longitudinal crown number may refer to the scheme of obtaining the transverse crown number in step 120.
The horizontal crown word number is a character string which is arranged horizontally, the first longitudinal crown word number and the second longitudinal crown word number are character strings which are arranged longitudinally, and for the three character strings, the character strings are stored in an array mode or a linked list mode and the like after being identified.
And 150, if at least two of the transverse crown number, the first longitudinal crown number and the second longitudinal crown number are the same, determining that the crown number identification is successful.
The determination of whether the crown number is successfully identified may be performed by:
1. and if the three crown word numbers are the same, determining that the crown word number identification is successful.
2. And if two crown word numbers are the same and the other crown word number is identified wrongly or fails, determining that the crown word number is identified successfully.
3. And if the three recognition results are different from each other, determining that the crown word number recognition fails.
According to the embodiment of the invention, the serial numbers of three positions on the paper money are identified, and the serial numbers can be successfully identified as long as at least two of the serial numbers of the three positions are consistent. In the prior art, only one crown word number is identified, and if the crown word number cannot be identified, the identification of the crown word number fails, and at this time, misjudgment may be caused. When one crown word number cannot be identified or is identified incorrectly, the embodiment of the invention can determine whether the identification of the crown word number is successful or not by comparing the other two crown word numbers, thereby improving the identification efficiency of the crown word number. In addition, because the embodiment of the invention can identify the serial numbers of a plurality of crown words of the paper money, the manufacturing difficulty of counterfeit paper money can be increased, the paper money is not easy to copy, and the safety of the paper money is improved.
Example two
In the technical solution provided in the first embodiment, at least two identical crown word numbers may exist on the banknote, but the identical crown word numbers are false crown word numbers, and at this time, a false judgment may occur according to the solution of the first embodiment.
Based on this, the embodiment of the present invention further provides a method for identifying a crown word number of a banknote, as further described in the first embodiment, as shown in fig. 4, before determining that identification of the crown word number is successful in step 150, the method further includes: determining whether the same crown number is true, step 150 can be performed as follows:
and 151, if at least two of the transverse crown number, the first longitudinal crown number and the second longitudinal crown number are the same, judging whether the same crown numbers are true. If true, execution is made 152, otherwise, step 153 is performed.
And when judging whether the same crown word number is true, comparing according to a correct crown word number set prestored locally to determine whether the number is true. Or may be sent over the network to a server which determines whether the number is genuine.
And step 154, outputting the identification failure information of the crown word number.
The failure message may be an alarm or may be a signal to flash an indicator light or change the color of an indicator light.
According to the technical scheme provided by the embodiment, the authenticity of the same crown word number can be detected when the fact that the paper money has at least two same crown word numbers is determined, and the accuracy of crown word number identification is further improved.
Since the different denominations of the banknotes have different sizes, the positions of the first preset area and the second preset area will also change, for example, the positions of the crown numbers of the 100 yuan denomination banknotes are different from those of the 50 yuan denomination banknotes. If a banknote with a face value of 50 dollars is recognized according to the position of the crown number of the 100 dollar banknote, the problem of failure in recognition of the crown number occurs.
Based on this, an embodiment of the present invention further provides a method for identifying a crown word number of a banknote, as shown in fig. 5, before identifying an image in a first preset area to obtain the transverse crown word number in step 110, the method further includes:
The identification of the denomination of a banknote may use the identification scheme of the banknote denomination in the prior art of banknote validation. For example: the invisible denomination number of the upper right corner of the front face of the paper currency is determined, or the white watermark of the lower left corner of the front face of the paper currency is determined, and the like.
And 102, determining first coordinate information of a first preset area and second coordinate information of a second preset area according to the denomination of the paper money.
At this time, step 110 identifies the image in the first preset area to obtain the horizontal crown number, which can be implemented by the following method:
and 110', identifying the image in the first preset area according to the first coordinate information to obtain a transverse crown word number.
and 120', identifying the image in the second preset area according to the second coordinate information to obtain a first longitudinal crown word number.
and 140', under the light with the preset wavelength, identifying the image in the second preset area according to the second coordinate information to obtain a second longitudinal crown word number.
According to the technical scheme provided by the embodiment, the coordinate information of the first preset area and the second preset area can be determined according to the face value of the paper money, the image containing the crown word number can be accurately found according to the determined coordinate information, and therefore the reliability of crown word number identification is improved.
The embodiment of the present invention further provides a method for identifying a crown word number of a banknote, and as a further description of the above embodiment, the embodiment provides a method for identifying a crown word number, which specifically includes:
identifying the image in the first preset area by using a neural network algorithm to obtain the transverse crown word number;
and/or the presence of a gas in the gas,
identifying the image in a second preset area by using a neural network algorithm to obtain the first longitudinal crown word number;
and/or the presence of a gas in the gas,
and identifying the image in the second preset area by using a neural network algorithm to obtain the second longitudinal crown word number.
The neural network algorithm can refer to related methods provided in the prior art, and details are not described herein.

In implementing the above embodiment, if ultraviolet rays are applied to the entire bill, there is no need for the identification of the crown number in the other area than the second preset area, and the ultraviolet rays irradiated to the other area are wasted.
Based on this, as shown in fig. 6, step 130 of applying light with a preset wavelength to the banknote may be implemented by the following method:
step 130', applying light with a predetermined wavelength to the second predetermined region.
In the technical scheme provided by the embodiment, because the area of the second preset area is smaller than that of the whole paper money, when light with preset wavelength is applied to the second preset area, the power consumption of the ultraviolet emitting device can be saved, and the cost of identifying the serial number is reduced.
