Method and device of extracting specific information in standard card

Abstract

A method of extracting particular information in a standard card is disclosed herein. The method includes: acquiring a card image of a standard card having particular information to be extracted; identifying an image region containing the particular information in the card image; and extracting and outputting the image region as an independent image. Thus, an image related to the part of the particular information only can be obtained from the standard card conveniently, quickly and accurately, thereby improving the working efficiency. In addition, the present disclosure further provides an apparatus of extracting particular information in a standard card and a method of inputting particular information of a standard card in 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, thereby reducing the workload. efficiency
