Problems solved by technology

[0004] In the process of realizing the present invention, the inventor found that the prior art has the following defects: the infrared reflective detection method mainly uses the scheme of one emission and one reception for detection, and its resolution is low, and the detection results are affected by the old and new banknotes, the face value of banknotes and temperature changes have serious effects on
The detection method by measuring the thickness of banknotes has high requirements on the consistency of the structure, and the influence of vibration needs to be eliminated, so it is difficult to control the consistency of production
It can be seen that the comprehensive detection rate of existing banknote stickers is relatively low.

Embodiment 1

[0033] figure 1 It is a flow chart of a detection method for banknote stickers provided by Embodiment 1 of the present invention. This embodiment is applicable to the detection of banknote stickers. The method can be performed by a detection device for banknote stickers. The device can be composed of It can be realized by means of software and / or hardware, and can generally be integrated in various banknote identification devices (typically, various types of sorting machines or ATMs). Such as figure 1 As shown, the method includes the following operations:

[0034] S110. Acquire the fluorescence image of the banknote to be tested, and perform binarization processing on the fluorescence image to obtain the binary image of the banknote to be tested.

[0035] Wherein, the banknote to be tested is a banknote that needs to detect whether there is a sticker. In this embodiment of the present invention, optionally, the sticker may include an adhesive tape.

Embodiment 2

[0050] figure 2 It is a flow chart of a detection method for banknote stickers provided by Embodiment 2 of the present invention. This embodiment is embodied on the basis of the above-mentioned embodiments. In this embodiment, the binarization of the image according to Carry out sum value traversal calculation in the first traversal order, and perform sum value traversal calculation on the binarized image at the refinement traversal position according to the second traversal order, and determine whether the banknote to be tested is based on the sum value calculation result There are concrete implementations of stickies. Correspondingly, such as figure 2 As shown, the method of this embodiment may include:

[0051] S210. Acquire a fluorescence image of the banknote to be tested, and perform binarization processing on the fluorescence image to obtain a binary image of the banknote to be tested.

[0052] S220. For the binarized image, sequentially calculate the sum value in ...

Embodiment 3

[0066] Figure 3a It is a flow chart of a method for detecting paper currency stickers provided by Embodiment 3 of the present invention. This embodiment is embodied on the basis of the above-mentioned embodiments. In this embodiment, it is provided to further determine whether there are stickers in banknotes. specific implementation. Correspondingly, such as Figure 3a As shown, the method of this embodiment may include:

[0067] S310. Acquire a fluorescence image of the banknote to be tested, and perform binarization processing on the fluorescence image to obtain a binary image of the banknote to be tested.

[0068] S320. For the binarized image, sequentially calculate the sum value within the first preset range according to the traversal sequence from top to bottom or from left to right.

[0069] Wherein, when the first traversal order is from top to bottom, the first preset range is the range formed by the set height value and the binarized image width value; when the f...

Abstract

The invention discloses a banknote sticker detection method, device and equipment. The method comprises steps of obtaining a fluorescence image of a to-be-detected banknote, carrying out binarizationprocessing of the fluorescence image, and obtaining a binarization image of the to-be-detected banknote; performing sum value traversal calculation of the binarized image according to a first traversal sequence, and obtaining a position of which the sum value meets a preset condition as a refined traversal position; and performing sum value traversal calculation of the binarized image at the refined traversal position according to a second traversal sequence, and determining whether the to-be-detected banknote has a sticker or not according to a sum value calculation result. The method is advantaged in that a detection rate of banknote stickers can be improved.

Description

technical field [0001] The invention relates to the technical field of banknote identification, in particular to a method, device and equipment for detecting banknote stickers. Background technique [0002] As a medium of exchange, banknotes are widely circulated in all aspects of social life. In the process of circulation, banknotes will inevitably be worn and become damaged or old. In life, people often use stickers (such as adhesive tape) to deal with the damaged currency and continue to use it, but the current common money detectors and ATM (Automatic Teller Machine, automatic teller machine) and other equipment cannot accurately identify this kind of currency with stickers. banknotes, even causing equipment damage when recognizing such banknotes. [0003] In the prior art, two methods are usually used to detect the paste in the banknotes. A light sensor is used to distinguish the unique characteristics of the infrared light reflectance of banknotes with stickers (suc...
