Example Embodiment

[0063] Example one

[0064] See attached figure 1 , Is a schematic flow chart of a bill authentication method provided in the first embodiment of the present invention. The method is suitable for scenarios where banks or financial institutions perform anti-counterfeiting and authentication of valuable bills. The method is executed by a bill authentication device, which can be implemented by software and / Or hardware implementation, which can be integrated into the bill authenticator or financial transaction equipment. The method specifically includes the following steps:

[0065] S110: Binarize the fluorescence area of ​​the fluorescence image of the bill to be authenticated to obtain the binarized fluorescence area.

[0066] It should be noted that the fluorescent image of the bill to be authenticated refers to the image of the bill to be authenticated under the irradiation of an ultraviolet light source, which can be obtained by using an image acquisition device, and the fluoresc...

Example Embodiment

[0076] Example two

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

[0078] S210: Calculate the difference between the target pixel to background pixel ratio of each block of the binarized fluorescent area and the ratio of the template target pixel to the background pixel of the corresponding block of the detection template.

[0079] It should be noted that, generally, 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 ...

[0091] Example three

[0092] image 3 It is a schematic flowchart of a bill authentication method provided in the third embodiment of the present invention. This embodiment is optimized on the basis of the foregoing embodiment. The method may specifically include the following steps:

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

[0094] Specifically, the fluorescence image of the bill to be authenticated may be obtained by using an image acquisition device, which may be a camera or a terminal device equipped with a camera, such as an image sensor. Specifically, the image acquisition device acquires The image of the bill to be authenticated under the ultraviolet light source.

[0095] S320: Determine the boundary of the bill to be authenticated in the fluorescence image of the bill to be authenticated.

[0096] Specifically, the boundary points of the bill to be authenticated may be found by using a boundary tracking method, and then the boundary points ...

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...
