Identification method for information carrier comprising multi-type identifications

Abstract

The invention brings forward an identification method for an information carrier comprising multi-type identifications. The information carrier can be a product label. By use of auxiliary positioning identification and a corresponding positioning identification detection identification algorithm, auxiliary positioning identifications on the information carrier are automatically identified, such that automatic positioning of multi-type data is realized. By use of an image identification algorithm, such information as characters, bar codes, display contents of display screens, two-dimensional codes, images and the like can be simultaneously identified, and the electronic display screens can display such contents as the characters, the bar codes, the two-dimensional codes, the images and the like, such that the information carrier has abundant information, and the identification results are accurate and reliable. Compared to bar code identification, two-dimensional code identification and image identification, character identification is smaller in characters and high in character segmentation and character identification difficulty. In order to ensure the accuracy of the character identification, the identification results are verified for the character identification by use of already known character lengths.

Description

Technical field [0001] The invention relates to an identification method for an information carrier containing multiple types of identifications. The information carrier may be a product label, which contains multiple types of identifications including character identification, barcode identification and two-dimensional code identification. Background technique [0002] With the continuous development of digital image technology, it is not only possible to recognize numbers and dial scales through computer vision technology, but also to recognize characters, bar codes and two-dimensional codes. The application fields of computer vision technology are becoming more and more diverse. Some inventors have proposed methods for recognizing characters in images. Peking University and Founder Group proposed a segmentation method for verification code recognition (patent number: 201110287721.1), which provides a method for extracting characters from verification code images in web pages. ...

But the case is just plate counting and food label recognition

Patent 201310140900.1 relates to an ERP data identification method that supports multiple identification technologies. This solution can only be identified separately on the same carrier, and cannot identify multiple types of identification information at the same time after scanning the information carrier.
