Embodiment 1

[0035] Such as figure 1 As shown, the method includes the following steps:

[0036] S101, first collect images of mobile banknote numbers through a line array image sensor;

[0037] S102, converting the analog signal into a digital signal and inputting it into the DSP processor;

[0038] S103, then the DSP processor preprocesses the collected number image;

[0039] S104, finally perform recognition processing on the banknote number image after the preprocessing, and save the recognition result to a designated storage location, such as a data memory.

Embodiment 2

[0041] The method includes the following steps:

[0042] S101, first collect images of mobile banknote numbers through a line array image sensor;

[0043] Preferably, the numbers include:

[0044] The serial number arranged horizontally on the left side of the banknote and the serial number arranged vertically on the right side of the banknote.

[0045] S102, converting the analog signal into a digital signal and inputting it into the DSP processor;

[0046] S103, then the DSP processor preprocesses the collected number image;

[0047] Locate the position of the number in the image and perform binarization on it;

[0048] Denoising is performed on the binarized image. Wherein, the binarization adopts a method based on threshold segmentation to define the threshold by itself.

[0049] S104, finally perform recognition processing on the banknote number image after the preprocessing, and save the recognition result to a designated storage location, such as a data memory.

Embodiment 3

[0058] Such as figure 2 As shown, the system includes the following parts: image acquisition module 11, DSP core module, photoelectric switch, serial port communication module and LCD.

[0059]Image collection module 11, the main function of this module is to use the linear image sensor to collect the image of the banknote number in motion, and the line array image sensor will output the collected number image in the form of an analog signal, and the analog signal is a voltage signal. It is amplified by an operational amplifier, converted to a digital signal by an analog-to-digital converter, and then level-shifted to enter a microcontroller. This part of the circuit before the image signal enters the microcontroller becomes the number acquisition circuit. Since the ATM cash out process is one by one, in the whole cash out module, the banknotes are first removed from the cash box by vacuum or friction. Banknotes are output sequentially, and pass through a series of sensors, ...

Abstract

The invention discloses a banknote number identification and management method, comprising: collecting the number image of the moving banknote through a linear array image sensor; converting an analog signal into a digital signal and inputting it into a DSP processor; The number image is preprocessed; the banknote number image after the pretreatment is analyzed, and the recognition result is stored in a designated memory. The invention also discloses a banknote number recognition and management system. By adopting the scheme of the invention, banknote numbers can be automatically collected and identified and recorded and stored during the banknote output process, and can also be connected with printing equipment to facilitate printing.

Description

technical field [0001] The invention belongs to the field of photoelectric technology, and in particular relates to a banknote number identification and management method and system. Background technique [0002] The counterfeiting of existing banknotes is mainly used for the fourth and fifth sets of RMB, and there is no corresponding number identification and management method for the new 2015 version of RMB that was newly launched last year. The number designed for the 2015 version of RMB is a horizontal and vertical double number. The lower left of the front of the face adopts a horizontal number. The crown and the first two digits are dark red, the last six digits are black; the vertical number on the right is blue. This increases the difficulty of counterfeiting and reduces the generation of counterfeit money, but the existing system cannot recognize the characteristics of this double number. Contents of the invention [0003] In view of this, the present invention p...
