[0001] The present application relates to the field of banknote detection technology, in particular to a banknote authenticity detection system and device. BACKGROUND

[0002] With the increasing frequency of economic activities, the circulation of counterfeit currency has become a major problem plaguing the financial system. Therefore, existing authenticity detection technology mainly relies on magnetic ink induction, infrared transmission analysis, fluorescence reaction detection and other identification methods. Although these technologies are effective, they still need to be improved in terms of portability, cost control and accuracy.

[0003] With the increasing popularity of online payments, cash payments are becoming less and less common, but some customers still use paper currency for small denomination transactions. Due to the size of the equipment, many offline stores no longer provide point-of-sale machines with paper currency authenticity verification functions to reduce the occupied area, and the detection of small denomination paper currency is not convenient. During detection, only ultraviolet light is usually used for detection, which can easily lead to false detection. SUMMARY

[0004] To solve the problem of the detection of small denomination paper currency by the point-of-sale machine in the prior art, which is not convenient and usually only uses ultraviolet light for detection, which can easily lead to false detection, the present application provides a banknote authenticity detection system, the specific scheme is as follows.

[0005] A banknote authenticity detection system, comprising a light source control module, an acquisition module, a processing module, a judgment module and a display module.

[0006] The light source control module is used to emit light source to irradiate the paper currency, and the light source includes ultraviolet light, infrared light and white light.

[0007] The acquisition module is used to acquire the images of the paper currency under the irradiation of ultraviolet light, infrared light and white light, respectively.

[0008] The processing module is used to process the three types of paper currency images acquired by the acquisition module and integrate the anti-counterfeiting features of the paper currency.

[0009] The judgment module is used to judge the paper currency image to obtain paper currency authenticity data.

[0010] The display module is used to display the paper currency authenticity result and the difference between the paper currency and the true currency range features.

[0011] By adopting the above technical scheme, the light source regulation module can emit ultraviolet rays, infrared rays and white light, and the paper currency image under the irradiation of each different light source is acquired by the acquisition assembly, and then the paper currency image is judged by the judgment module, so that the authenticity of the paper currency can be judged, and the authenticity result can be displayed by the display module. Once, three kinds of detection can be performed, the convenience is improved, and the wrong detection situation is reduced.

[0012] Optionally, the standard model library is further included, and the standard model library stores the anti-counterfeiting feature data of the real paper currency under the irradiation of ultraviolet rays, infrared rays and white light. The standard model library is used for the judgment module to compare the paper currency image with the anti-counterfeiting features of the real paper currency.

[0013] By adopting the above technical scheme, the standard model library is set, and when the paper currency image is obtained, the paper currency image to be detected can be directly compared with the anti-counterfeiting features of the real paper currency, the wrong detection situation is reduced, and the detection accuracy is further improved.

[0014] Optionally, the control module is further included, and the control module is used for controlling the light source regulation module and the display module.

[0015] By adopting the above technical scheme, the control module is set, and the control module can adjust the light source regulation module to control the light source, and control the display module to display the data to be displayed.

[0016] Optionally, the cleaning module is further included, and when the processing module judges that there is a defect on the paper currency, the cleaning module can spray cleaning agent towards the paper currency and clean.

[0017] By adopting the above technical scheme, the cleaning module can attempt to clean when detecting that there is a defect on the paper currency, and it is more convenient to judge the anti-counterfeiting features of the paper currency after cleaning, the false detection situation is further reduced, and the detection accuracy is further improved.

[0018] Optionally, the drying module is further included, and the drying module is used for drying the cleaning agent after the cleaning module works, and sends a signal to the acquisition module to acquire the paper currency image again after the drying module works.

[0019] By adopting the above technical scheme, the drying module is set, and the paper currency can be quickly dried after cleaning, and the damage caused by the moisture of the paper currency is reduced.

[0020] Optionally, the AI repair module is further included, and when the processing module processes the paper currency image again after cleaning and drying and still has defects, the AI repair module is used for repairing part of the paper currency image and marking the repaired anti-counterfeiting feature part. The paper currency image repaired by the AI repair module is transmitted to the judgment module for judgment.

[0021] By adopting the technical scheme, the AI repairing module is arranged, and the AI algorithm can be used to complete the banknote when the features of the banknote are incomplete. The AI repairing module can complete the banknote according to the existing features of the banknote, so that the completed features are correct when the existing features are completely correct. However, when the existing features are fake, the completed features will also be completed. In the comparison, the banknote will not be directly judged as a fake banknote due to defects, reducing the influence of the missing part of the features on the true and false judgment. When the defects are small and few, the true and false of the banknote can be directly judged. However, when the defects are large, the completed part can be marked, and the true and false of the banknote can be further judged, reducing the situation that the AI completion is completely different from the original banknote next time, and further improving the accuracy of the judgment.

[0022] To solve the problem that the existing point counting machine is not convenient for detecting small denomination banknotes, and usually only uses ultraviolet light for detection during detection, which is prone to misjudgment, the application also provides a banknote true and false detection device, and the specific scheme is as follows.

At the same time, the banknote can be irradiated by the ultraviolet lamp, the infrared lamp and the white light lamp, and the corresponding banknote image can be acquired. The detection can be completed by comparing the banknote image with the anti-fake features of the real banknote. The whole is more convenient to carry, and single small denomination banknotes can be detected to improve the detection accuracy.

[0047] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0048] Example 1

[0049] like Figure 1 As shown, a banknote authenticity detection system includes a light source control module 1, an acquisition module 2, a processing module 3, a judgment module 4, and a display module 5. The light source control module 1 emits a light source to illuminate the banknote; the light source includes ultraviolet light, infrared light, and white light. The acquisition module 2 acquires images of the banknote under ultraviolet light, infrared light, and white light illumination, respectively. The processing module 3 processes the three banknote images acquired by the acquisition module 2 and integrates the banknote's anti-counterfeiting features. The judgment module 4 judges the acquired banknote images to obtain banknote authenticity data. The display module 5 displays the banknote authenticity result and compares the differences between the banknote and genuine banknotes in terms of features. In specific implementation, the light source control module 1 first illuminates the banknote with one type of light, the acquisition module 2 obtains the first image, and then the banknote images under all three light sources are repeatedly acquired to determine the authenticity of the banknote. The result is then displayed through the display module 5. In other embodiments, a fluorescence reaction module can be added for further banknote detection.

[0050] like Figure 1 As shown, it also includes a standard model library 41, which stores anti-counterfeiting feature data of genuine banknotes under ultraviolet, infrared, and white light illumination. The standard model library 41 is used by the judgment module 4 to compare the banknote image with the anti-counterfeiting features of genuine banknotes. In specific implementation, the standard model library 41 stores anti-counterfeiting feature data of banknotes of various denominations under various light sources used for detection. When judging the authenticity of banknotes, the authenticity conclusion can be drawn by comparing the image and data, thus improving the accuracy of detection.

[0051] likeFigure 1 As shown, it also includes a control module 6 for controlling the light source regulation module 1 and the display module 5. In actual implementation, the selection of the light source and the display of the image and detection results by the display module 5 are all controlled by the control module 6.

[0052] As shown, it also includes a control module 6 for controlling the light source regulation module 1 and the display module 5. In actual implementation, the selection of the light source and the display of the image and detection results by the display module 5 are all controlled by the control module 6. Figure 1 As shown, it also includes a cleaning module 7 capable of spraying cleaning agent towards the banknote and cleaning when the processing module 3 judges that there is a defect on the banknote. It also includes a drying module 72 for drying the cleaning agent after the cleaning module 7 works, and sends a signal to the acquisition module 2 to acquire the image of the banknote again after the drying module 72 works. In actual implementation, the cleaning module 7 can spray alcohol or other small amount of cleaning agent with mildew and stain removal towards the banknote, and then dry the cleaning agent by drying, which can reduce the influence of the defect on the accuracy of the detection of the banknote to a certain extent.

[0053] As shown, it also includes a control module 6 for controlling the light source regulation module 1 and the display module 5. In actual implementation, the selection of the light source and the display of the image and detection results by the display module 5 are all controlled by the control module 6. Figure 1 As shown, it also includes an AI repair module 31 for repairing part of the image of the banknote and marking the repaired anti-counterfeiting feature part when the processing module 3 judges that there is still a defect in the image of the banknote acquired again after cleaning and drying, and the banknote image repaired by the AI repair module 31 is transmitted to the judgment module 4 for judgment. In actual implementation, when the defect is small, the banknote image repaired by the AI repair module 31 is completed according to the anti-counterfeiting feature on the banknote, at this time, the banknote image repaired will not deviate from the banknote image in the standard database, which can reduce the false detection caused by the defect. When the defect is large, the banknote may not have anti-counterfeiting features or have too few anti-counterfeiting features to be repaired, at this time, the banknote image repaired by the AI repair module 31 no longer has comparison significance, so the banknote image repaired by the AI repair module 31 is not transmitted to the judgment module 4 for judgment.

[0054] Working principle: after the banknote is put in, the light source regulation module 1 irradiates the banknote with multiple light sources and acquires the image of the banknote, at the same time, the banknote with defects is cleaned and repaired, then by comparing the data in the standard model library 41, the authenticity of the banknote can be judged.
