Abstract

The invention discloses a method and a device for identifying characters in a card and certificate and computing equipment. The identification method comprises the steps of obtaining a card and certificate image, wherein the card and certificate image comprises at least one type of character sequence; Obtaining various types of character sequence images from the card image by using a first targetdetection model to obtain at least one first character sequence image; Performing block binarization processing on each first character sequence image to obtain a corresponding second character sequence image; Obtaining a single character image from the second character sequence image by using a second target detection model; And for each single-word image obtained from the second character sequence image, identifying character information in the single-word image.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a method, a device and a computing device for recognizing characters in a card. Background technique [0002] With the development of Internet technology, whether it is in the business of auto finance, second-hand car transactions, etc., or on the e-commerce platform dominated by online payment, a large number of bank card or certificate text information input work is involved. The automatic reading of card information can replace a large number of tedious manual entry, which can effectively improve the efficiency of information entry and save management costs. At the same time, the high-precision identification of Chinese character information in cards can accurately read user information into the computer system, improve the service quality of Internet services, and bring good user experience to customers, so it has important research significance. [0003] The extrac...
