A method and device for extracting specific information from a standard card

Abstract

This application provides a method for extracting specific information in a standard card. The relevant parameters and shape information of the standard card are determined according to the standard card template image, including: obtaining the card image of the standard card to be extracted with specific information; identifying the card image containing the The image area of ​​specific information; the image area is extracted as an independent image and output; thus, it is possible to conveniently, quickly and accurately obtain images that only involve specific information in standard cards, and improve work efficiency. In addition, the present application also provides a device for extracting specific information in a standard card, and a method for inputting specific information in a standard card on a mobile terminal.

Description

technical field [0001] This application relates to the field of computer application technology, in particular to a method and device for extracting specific information in standard cards. On the basis of the above, this application also provides a method for inputting specific information in standard cards on a mobile terminal. Background technique [0002] With the development of society, cards are widely used in life and work due to their advantages of portability, such as bank cards, medical insurance cards, membership cards and so on. The cards themselves have standard card attributes and associated information. For example, a bank card records the bank card number, validity period, etc., and its dimensions are generally 53.98mm in width and 85.6mm in length. [0003] In the era of mobile Internet, payment methods such as mobile payment or e-wallet provide convenience for life services. The payment method of the mobile terminal has been widely used in daily life. Mos...

Problems solved by technology

[0006] When the user adopts the first method, it is necessary to input on the screen of the mobile phone while checking the bank card during the input process. However, due to the long bank card number, the input is cumbersome and easily leads to input errors.

[0007] When the user adopts the second method, firstly, the information on the bank card surface needs to be printed on the surface of the bank card, and when obtaining the bank card information, the card information such as the card number can be obtained by scanning the QR code of the bank card with the camera device of the mobile terminal. , however, using this method: on the one hand, it is necessary to print the two-dimensional code information on the bank card, therefore, it is necessary to replace the existing bank card without the two-dimensional code, resulting in an increase in cost; on the other hand, due to the two-dimensional code It is not intuitive information, which must be identified by means of identification equipment, and the two-dimensional code image must be placed within the scanning frame during the identification process. Therefore, this method is not only limited by the conditions of use, but also by the shooting angle. Users poor experience

[0008] When the user adopts the third method, due to the impact of OCR (Optical Character Recognition, Optical Character Recognition) recognition error rate, after the recognition is completed, the user needs to compare the bank card with the recognition results displayed on the mobile terminal one by one, and then decrease productivity
