Problems solved by technology

[0003] At present, when identifying banknotes, the identification method usually adopted is to identify the entire banknote, but in fact the anti-counterfeiting features of the banknote will not spread all over the entire banknote. Therefore, when identifying the entire banknote, not only The workload of recognition is heavy, and the speed of recognition is not high

Embodiment 1

[0036] figure 1 The implementation flow of the banknote detection method provided by Embodiment 1 of the present invention is shown, and the details are as follows:

[0037] In step S101, the front fluorescence image and the back fluorescence image of the banknote to be detected are obtained;

[0038] In the embodiment of the present invention, the light in the non-fluorescence band can be filtered by the image sensor, the front and back sides of the banknote to be detected can be scanned respectively, and the scanned front image can be determined as the front fluorescence image of the banknote to be detected. The scanned back image is determined to be the back fluorescence image of the banknote to be detected, wherein the type of the above image sensor may be a contact image sensor or other type of image sensor, which is not limited here. The banknotes to be tested above specifically refer to RMB issued by the People's Bank of China and circulated in China. The front side o...

Embodiment 2

[0088] Figure 9 A specific structural block diagram of the banknote detection device provided by the second embodiment of the present invention is shown, and for the convenience of description, only the parts related to the embodiment of the present invention are shown. The banknote detection device 9 includes: an acquisition unit 91 , a positioning unit 92 , a reverse fluorescent area determination unit 93 , a detection unit 94 , and a detection result determination unit 95 .

[0089] Wherein, the obtaining unit 91 is used to obtain the front fluorescent image and the reverse fluorescent image of the banknote to be detected;

[0090] A positioning unit 92, configured to locate the front fluorescent area in the front fluorescent image, wherein the fluorescent area includes a fluorescent digital pattern;

[0091] The reverse fluorescent region determination unit 93 is configured to determine the reverse fluorescent region corresponding to the front fluorescent region in the a...

Embodiment 3

[0129] Figure 10 It is a schematic diagram of the electronic device provided by Embodiment 3 of the present invention. like Figure 10 As shown, the electronic device 10 of this embodiment includes: a processor 100, a memory 101, and a computer program 102 stored in the memory 101 and operable on the processor 100, such as an application program management program. When the above-mentioned processor 100 executes the above-mentioned computer program 102, the steps in the embodiments of the above-mentioned application program management methods are implemented, for example figure 1 Steps S101 to S104 are shown. Alternatively, when the above-mentioned processor 100 executes the above-mentioned computer program 102, the functions of each unit in the above-mentioned device embodiments are realized, for example Figure 9 Function of units 91 to 94 shown.

[0130] Exemplarily, the above-mentioned computer program 102 may be divided into one or more units, and the one or more uni...

Abstract

The present invention discloses a paper money detection method, a paper money detection device, an electronic device and a computer readable storage medium. The paper money detection method comprisesthe steps of: obtaining a front fluorescence graph and a reversed fluorescence graph of paper money to be detected; positioning a front fluorescent area in the front fluorescence graph, wherein the fluorescent area comprises a fluorescent digital pattern; according to a positioning result, determining a reversed fluorescent area corresponding to the front fluorescent area in the reversed fluorescence graph; detecting whether the image features of the reversed fluorescent area meet preset image feature conditions or not, wherein the image features comprise texture features and shape features; and if the image features of the reversed fluorescent area do not meet the image feature conditions, determining that the paper money to be detected is abnormal paper money. The detection efficiency ofthe abnormal paper money can be improved.

Description

technical field [0001] The invention belongs to the technical field of banknote identification, and in particular relates to a banknote detection method, a banknote detection device, electronic equipment and a computer-readable storage medium. Background technique [0002] Banknotes are value symbols issued and compulsorily used by countries or regions. However, in order to make profits, lawbreakers have produced counterfeit or altered banknotes (collectively referred to as abnormal banknotes) for use and circulation in the market. These abnormal banknotes have destroyed society. The principle of credit interferes with the normal order of currency circulation. If abnormal banknotes are flooded, it will also cause national economic instability, and even lead to economic, social and social crises. Therefore, in order to maintain the financial order of the society and prevent abnormal banknotes from circulating in the market, the anti-counterfeiting features of banknotes in va...
