Embodiment 1

[0055] figure 1 It is a schematic flow chart of a method for detecting abnormal thickness of banknotes provided in Embodiment 1 of the present invention. The method is suitable for detecting abnormal thickness of banknotes. The method can be executed by a device for detecting abnormal thickness of banknotes. The device can be implemented by software and / or It is realized by hardware, and generally can be integrated in the equipment for detecting the abnormal thickness of banknotes. see figure 1 , the method includes the following steps:

[0056] S110. Obtain thickness data corresponding to each region in the banknote to be detected, where the thickness data includes: a thickness value.

[0057]Specifically, the image sensor collects the image signal of the banknote to be detected to form banknote image data, the thickness sensor collects the thickness signal of the banknote to be detected to form banknote thickness data, and then maps the image signal and the thickness signa...

Embodiment 2

[0089] Please refer to the attached image 3 , is a schematic structural diagram of a banknote thickness abnormal detection device provided in Embodiment 2 of the present invention, the device specifically includes the following modules:

[0090] The thickness data acquisition module 21 is used to acquire the thickness data corresponding to each area in the banknote to be detected, and the thickness data includes: a thickness value;

[0091] Detection module determination module 22, configured to determine a corresponding detection template according to the attribute information of the banknote to be detected;

[0092] The banknote thickness judging module 23 is used for judging whether the thickness of the banknote to be detected is abnormal according to the template banknote thickness data of each area of ​​the detection template and the thickness data of the corresponding area of ​​the banknote to be detected.

[0093] In this embodiment, the thickness data corresponding t...

Abstract

The present invention discloses a paper money thickness anomaly detecting method and device. The method includes the following steps that: thickness data corresponding to each region of paper money to be detected are obtained, wherein the thickness data include thickness values; a corresponding detection template is determined according to the attribute information of the paper money to be detected; and whether the thickness of the paper money to be detected is abnormal according to the template paper money thickness data of each region of the detection template and the thickness data of the corresponding regions of the paper money to be detected. With the above paper money thickness anomaly detecting method and device adopted, accurate thickness anomaly detection can be ensured after difference influence is eliminated, and an algorithm is simple.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of banknote processing, in particular to a method and device for detecting abnormal thickness of banknotes. Background technique [0002] Banknote processing refers to sorting and categorizing different versions of banknotes, counting and counting banknotes, identifying true and false banknotes and identifying abnormal thickness of banknotes. Regarding the abnormal thickness of banknotes, banknotes are easily damaged and incomplete during the circulation process in the trading market. Stains and adhesives on banknotes can also cause abnormal thickness of banknotes. How to identify banknotes with abnormal thickness is the technical problem to be solved in the present invention. Contents of the invention [0003] The invention provides a method and device for detecting abnormal thickness of banknotes, so as to realize accurate identification of abnormal thickness of banknotes. ...
