Embodiment 1

[0062] figure 1 It is a flow chart of a banknote value identification method provided by Embodiment 1 of the present invention. The method of this embodiment can be performed by a banknote value identification device, wherein the device can be implemented by software and / or hardware, and generally can be integrated into financial equipment such as automatic ticket vending machines or banknote counters. Such as figure 1 As shown, the banknote currency value identification method provided in this embodiment specifically includes the following steps:

[0063] Step 110, acquiring the grayscale images of the background area and feature area of ​​the banknote to be tested.

[0064] Wherein, the banknote to be tested is preferably Iranian currency, and may also be other currencies (such as RMB or Indonesian rupiah) with obvious color difference areas on the surface of the banknote.

[0065] In the banknote identification process, the banknote grayscale image is the image detected ...

Embodiment 2

[0074] image 3 It is a flow chart of an Iranian currency value identification method provided by Embodiment 2 of the present invention. This embodiment is optimized on the basis of the foregoing embodiments. refer to image 3 , the embodiment of the present invention specifically includes the following steps:

[0075] Step 210, acquiring grayscale images of the background area and feature area of ​​the banknote to be tested.

[0076] Step 220: Calculate the background gray value according to the gray image of the background area, and determine the feature pixel points in the feature area that are different from the background according to the background gray value.

[0077] Step 230: Calculate the difference between the gray value of the feature pixel in the feature area and the background gray value, and use the sum of all the differences as the feature attribute.

[0078] Specifically, in the process of identifying the Iranian currency value, if the gray average value o...

Abstract

The invention discloses a paper currency value identification method and a paper currency value identification device. The paper currency value identification method comprises steps that gray level images of a background area and a characteristic area of to-be-detected paper currency are acquired; a background gray value is calculated according to the gray level image of the background area, and characteristic pixels different from the background are determined in the characteristic area according to the background gray value; and the value of the to-be-detected paper currency is identified according to the characteristic attribute of the characteristic pixels. By adopting the above mentioned technical scheme, conventional paper currency value calculation methods are simplified, and the reliability of the paper currency value identification is improved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of banknote detection, in particular to a method and device for identifying the value of banknotes. Background technique [0002] With the development of the economy, the circulation of banknotes is increasing, and intelligent unmanned toll collection systems based on banknote recognition technology have appeared in many industries. For example, banknote recognition technology is not only applied to automatic vending and ticket sales, but also to systems such as bank ATMs or automatic payment machines in business halls. At the same time, the invention of the banknote counter has also provided convenience for various industries. The application of the banknote currency value recognition device saves a lot of human resources and greatly improves work efficiency. [0003] The identification of banknote currency value is the basic identification part of banknote verification, and the ...
