Problems solved by technology

[0003] Existing banknote identification equipment can usually only identify the authenticity of banknotes, but cannot accurately detect spliced ​​banknotes
Especially for the detection of spliced ​​banknotes that are spliced ​​from two (or more) different authentic coins, the current technology is not very mature, and the detection rate of spliced ​​banknotes is low

Embodiment 1

[0030] figure 1 This is a flowchart of a method for detecting spliced ​​banknotes provided in Embodiment 1 of the present invention. This embodiment is applicable to the detection of spliced ​​banknotes. The method can be executed by a detection device for spliced ​​banknotes, which can be implemented by software and / or or hardware, and can generally be integrated in various banknote identification devices (typically, various sorting machines or ATMs and other devices). like figure 1 As shown, the method includes the following operations:

[0031] S110. Acquire a first set area image of a standard banknote and a second set area image of a banknote to be detected; wherein the first set area image and the second set area image are in the same position in the banknote.

[0032] Among them, the standard banknotes are normal real banknotes without defects (such as splicing, missing corners or pasting, etc.), and the banknotes to be tested are the banknotes to be detected. Corres...

Embodiment 2

[0046] figure 2 This is a flow chart of a method for detecting spliced ​​banknotes provided in the second embodiment of the present invention. This embodiment is embodied on the basis of the above-mentioned embodiment. In this embodiment, a method of combining the first local area A specific implementation manner of matching an image with the second local area image. correspondingly, as figure 2 As shown, the method of this embodiment may include:

[0047] S210: Acquire the first set area image of the standard banknote and the second set area image of the banknote to be detected.

[0048] S220: Divide the first set area image into a set number of first partial area images, and divide the second set area image into a set number of second partial area images.

[0049] S230. Perform sliding window matching on each of the first partial area images and each of the second partial area images, and calculate the first partial area image correspondingly between each of the first p...

Embodiment 3

[0079] Figure 3a This is a flow chart of a method for detecting spliced ​​banknotes provided in the third embodiment of the present invention. This embodiment is embodied on the basis of the above-mentioned embodiment. In this embodiment, another method of combining the first part of A specific implementation manner of matching the region image with the second partial region image. correspondingly, as Figure 3a As shown, the method of this embodiment may include:

[0080] S310: Acquire the first set area image of the standard banknote and the second set area image of the banknote to be detected.

[0081] S320: Divide the first set area image into a set number of first partial area images, and divide the second set area image into a set number of second partial area images.

[0082] S330. Perform sliding window matching between each of the first partial area images and each of the second partial area images, and calculate the first partial area image correspondingly betwee...

Abstract

The embodiment of the present invention discloses a detection method, device, financial equipment and storage medium for spliced ​​banknotes. The method includes: acquiring a first set area image of a standard banknote and a second set area image of the banknote to be detected; wherein, The position of the first set area image and the second set area image in the banknote is the same; the first set area image is divided into a set number of first partial area images, and the first set area image is divided into a set number of first partial area images. Two set area images are divided into a set number of second partial area images; the first partial area image is matched with the second partial area image, and according to the matching result, it is determined whether the banknote to be detected is a spliced ​​banknote . The technical solutions of the embodiments of the present invention can improve the detection rate of spliced ​​banknotes.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of banknote detection, and in particular, to a detection method, device, financial equipment, and storage medium for splicing banknotes. Background technique [0002] Spliced ​​banknotes are artificially connected banknotes by technical processing. As a kind of altered currency, the detection of spliced ​​banknotes has always been a difficulty in the detection of banknote identification equipment such as sorting machines and ATMs (Automatic Teller Machines). [0003] Existing banknote identification devices usually can only identify the authenticity of banknotes, but cannot accurately detect spliced ​​banknotes. Especially for the detection of spliced ​​banknotes formed by splicing two (or more) different genuine banknotes, the current technology is not very mature, and the detection rate of spliced ​​banknotes is low. SUMMARY OF THE INVENTION [0004] Embodiments of the present inv...
