Embodiment 1

[0064] Figure 1a It is a flow chart of a banknote identification method provided by Embodiment 1 of the present invention. The method of this embodiment can be executed by a banknote identification device, which can be implemented by means of hardware and / or software, and can generally be integrated in a banknote identification device. In the device with counterfeit authentication function. The method of this embodiment specifically includes:

[0065] S110. Obtain a grayscale image of a preset characteristic region of the banknote to be tested.

[0066] In this embodiment, the banknote to be tested may specifically be a banknote of any currency, and the preset characteristic area specifically refers to any area in the banknote to be tested, and may typically be a ram horn character area in RMB.

[0067] Generally speaking, when performing anti-counterfeiting detection on banknotes, the banknotes are first irradiated with infrared or ultraviolet light to obtain the grayscale ...

Embodiment 2

[0084] figure 2It is a flow chart of a banknote identification method provided by Embodiment 2 of the present invention. This embodiment is optimized on the basis of the above-mentioned embodiments. In this embodiment, it will be determined whether the edge image includes standard reference points according to the number of edge points in the row and the number of edge points in the column in the edge image. The optimization is as follows: The sum of the edge points of each reference row and the sum of the edge points of each reference column; judge whether there is a row whose edge point sum is greater than the preset row and threshold in each reference row; if there is an edge point sum in each reference row greater than the preset row and threshold , then continue to judge whether there are columns with edge points and greater than the preset column and threshold in each reference column, if there is no row in each reference row with edge points and greater than the preset...

Embodiment 3

[0110] image 3 It is a flow chart of a banknote identification method provided by Embodiment 3 of the present invention. This embodiment is optimized on the basis of the above-mentioned embodiments. In this embodiment, it will be determined whether the edge image includes standard reference points according to the number of edge points in the row and the number of edge points in the column in the edge image. The optimization is as follows: The edge value of all pixels within the preset range, where the edge value is the sum of the number of edge points in the row where the pixel is located and the sum of the number of edge points in the column where the pixel is located; determine whether any edge value in each pixel within the preset range is greater than the preset The pixel point of the edge value; if there is a pixel point with an edge value greater than the preset edge value in each pixel point within the preset range, then determine that the pixel point is a standard re...

Abstract

The embodiment of the invention discloses a banknote identification method and device. The method includes: acquiring a grayscale image of a preset characteristic region of the banknote to be tested; performing edge detection on the grayscale image of the preset characteristic region to obtain an edge image of the preset characteristic region; The number of edge points in the column determines whether the edge image includes a standard reference point; if the edge image includes the standard reference point, then determines the position of the standard reference point, and determines the matching position of the template information map and the edge image according to the position of the standard reference point; Information matching is performed on the edge image and the template information map, and the authenticity of the banknote to be tested is identified according to the information matching result. The technical solution of the embodiment of the present invention solves the technical defects of the cumbersome and computationally intensive process of banknote identification using the template matching method in the prior art, realizes the simplified process of template matching for banknote identification, greatly reduces the amount of calculation, and improves the The counterfeiting speed of banknotes.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of banknote processing, in particular to a banknote identification method and device. 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 can be applied not only 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 identification device saves a lot of human resources and greatly improves the work efficiency. [0003] Existing template matching techniques applied to banknote identification generally use the obtained grayscale image of the entire b...
