Problems solved by technology

When withdrawing money from an ATM, it is easy to forget to take out the card due to negligence, resulting in economic losses
In addition, the life of the magnetic strip is limited. After a certain number of swipes, the magnetic strip will be worn to varying degrees, resulting in bank card failure.
Although there is OCR optical character recognition technology at present, it is used for monochrome background and monochrome font, and its limitation is that it cannot extract the card number from the complex color background.

Embodiment 1

[0058] A method for automatic identification of bank card numbers based on digital image processing, comprising the following steps:

[0059] 1. Lead out the LED power supply wire from the wire hole, supply power, and the light emitted by the LED light passes through the lens and evenly illuminates the identification window 5.

[0060] 2. Take any bank card and insert it into the card slot of the box. After stabilization, the computer confirms the drawing.

[0061] 3. The camera 1 inside the box takes pictures, and the pictures are transmitted to the inside of the computer by the USB cable.

[0062] Fourth, use digital image processing software to read pictures for preprocessing. The processing process is grayscale, inversion, background removal, binarization, and noise removal of color images.

[0063] Fifth, by expanding the image laterally, the regions are connected. There are two types of connected regions: numeric regions and non-numeric regions.

[0064] 6. Character...

Abstract

The invention discloses an automatic band card number recognition device based on digital image processing. The device comprises a box, a computer and a display. A black light absorption material is arranged on the inner side of the box, a camera and an LED background light source are installed in the box, a recognition window with a card support is formed in the outer portion of the box, card surface image information of a bank card is extracted by a camera through photographing, the camera is connected with the computer via a data line and transmits the image information, and processed card number data is displayed by the display connected with the computer for outputting. The automatic band card number recognition device based on digital image processing provided by the invention adopts an optical non-contact type bank card number extraction mode, and is more convenient and durable compared with an existing bank card number recognition system based on magnetic stripe reading. The processing mode is based on universal computing software, so that an advantage of intelligently recognizing a bank card number is provided. The device of the invention can be applied to the social financial aspect such as automatic money depositing and withdrawing of banks and card number statistics of enterprise financial departments.

Description

technical field [0001] The invention relates to the technical field of digital image processing, in particular to an automatic identification device for bank card numbers based on digital image processing. Background technique [0002] The character recognition technology based on digital image processing is based on optical imaging, and uses the powerful processing power of digital image processing software to realize its recognition function. As a universal number, Arabic numerals play an important role in various fields such as economy and life. Therefore, the automatic number recognition technology has high practicability. Nowadays, the theoretical methods of handwritten number and printed number recognition have come up with new ones, which are mainly used in daily life aspects such as bill face value recognition, traffic management vehicle license plate recognition system, and apartment management house number recognition. [0003] Bank cards are closely related to s...
