Embodiment 1

[0064] Please refer to the attached figure 1 , is a schematic flow chart of a bill identification method provided by Embodiment 1 of the present invention. This method is applicable to the scene of banks or financial institutions conducting anti-counterfeit identification of valuable notes. The method is executed by a bill identification device, which can be controlled by software and / or hardware implementation, which can be integrated inside the bill validator or financial transaction equipment. The method specifically includes the following steps:

[0065] S110. Binarize the fluorescent area of ​​the fluorescent image of the bill to be identified to obtain a binarized fluorescent area.

[0066] It should be noted that the fluorescent image of the bill to be identified refers to the image of the bill to be identified under the irradiation of an ultraviolet light source, which can be obtained using an image acquisition device, and the fluorescent area is an area with a fluor...

Embodiment 2

[0077] figure 2 It is a schematic flow chart of a bill identification method provided by Embodiment 2 of the present invention. On the basis of the above-mentioned embodiments, this embodiment "blocks each of the binarized fluorescent regions and detects the corresponding blocks of the template." Perform matching, and determine the authenticity of the bill to be identified according to the matching result" was optimized. The method specifically may include the following steps:

[0078] S210. Calculate the difference between the ratio of the target pixel point to the background pixel point of each of the binarized fluorescence region blocks and the ratio of the template target pixel point to the background pixel point of the corresponding block of the detection template.

[0079] It should be noted that, in general, if there is no signal deviation or signal interference during image acquisition, the number of pixels in the binarized fluorescent area block of the bill to be id...

Embodiment 3

[0092] image 3 It is a schematic flowchart of a bill identification method provided by Embodiment 3 of the present invention, and this embodiment is optimized on the basis of the foregoing embodiments. The method specifically may include the following steps:

[0093] S310. Acquire a fluorescent image of the bill to be identified.

[0094] Specifically, the fluorescent image of the bill to be identified can be obtained by using an image acquisition device, and the image acquisition device can be a camera or a terminal device equipped with a camera, such as an image sensor. Specifically, what the image acquisition device acquires is The image of the bill to be authenticated under the irradiation of ultraviolet light source.

[0095] S320. Determine a boundary of the bill to be identified in the fluorescent image of the bill to be identified.

[0096] Specifically, the boundary point of the bill to be identified can be found by using the method of boundary tracking, and then ...

Abstract

The embodiment of the invention discloses a bill discrimination method, device and equipment, and a storage medium. The method comprises steps of carrying out binarization on a fluorescence region of a fluorescence image of a to-be-discriminated bill so as to obtain a binarization fluorescence region; blocking the binarization fluorescence region so as to obtain multiple binarization fluorescence region blocks; matching the binarization fluorescence region blocks with corresponding blocks of detection templates, and determining the authenticity of the to-be-discriminated bill according to matching results. According to the invention, by carrying out binarization on the fluorescence image of the to-be-discriminated bill, blocking the binarization image and carrying out matching by use of multiple detection templates, time complexity of an algorithm can be reduced and discrimination rate of the bill authenticity is increased, there is no need to re-check the bill, high-speed reorganization requirements of the bill can be met and bill discrimination efficiency can be improved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of image processing, and in particular, to a bill identification method, device, equipment, and storage medium. Background technique [0002] As the documents and vouchers used in economic activities, bills have been widely used at present, such as securities, bills of lading, waybills, invoices, movie tickets, train tickets, tickets, etc., which are frequently used in everyone's daily life to these bills. It is precisely because of the importance of bills that various criminal activities of counterfeiting bills are also very rampant at present, which greatly disrupts the existing financial circulation system and disrupts the order of the entire economic activity, and thus brings great harm to the country, enterprises and individuals. There came a great loss. [0003] In order to prevent counterfeiting of bills, a variety of bill anti-counterfeiting methods have been proposed. Gen...
