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 bank card number automatic identification method based on digital image processing, comprising the following steps:

[0059] 1. Lead the LED power supply line out from the line hole, supply power, and the light emitted by the LED light will evenly shine on the identification window 5 after passing through the lens.

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

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

[0062] 4. Use digital image processing software to read pictures for preprocessing. The processing process is color image grayscale, inversion, background removal, binarization, and noise removal.

[0063] 5. By expanding the image horizontally, the region is connected. There are two types of connected regions: digital regions and non-digital regions.

[0064] 6. Character segm...

Abstract

An automatic identification device for bank card numbers based on digital image processing, comprising a box, a computer, and a display. There is a black light-absorbing material on the inside of the box, a camera and an LED background light are installed inside the box, and an identification window with a card tray is set up outside the box. The image information of the bank card is captured by the camera, and the camera is connected to the computer through a data cable and transmitted. The image information and the processed card number data are displayed and output by the monitor connected to the computer. The automatic bank card number recognition device based on digital image processing of the present invention adopts an optical non-contact bank card number extraction method, which is more convenient and durable than the existing bank card number recognition system based on magnetic stripe reading. Its processing method is based on general computing software, which has the advantage of intelligently identifying bank card numbers. It can be applied in social financial aspects such as bank automatic deposit and withdrawal, card number statistics of corporate finance department.

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] Character recognition technology based on digital image processing is based on optical imaging, and uses the powerful processing capability of digital image processing software to realize its recognition function. Arabic numerals, as universal numbers in the world, play an important role in various fields such as economy and life. Automatic digital recognition technology therefore has high practicability. Nowadays, the theoretical methods of handwritten and printed numbers recognition are being innovated, which are mainly used in daily life such as face value recognition of bills, vehicle license plate recognition system for traffic management, house number recognition for apartment management, etc. [0003] Bank cards are closely related to...
