Problems solved by technology

At this time, if you use the camera of the scanning device to scan the two-dimensional codes in the webpage one by one, there will be some problems: you need to use the camera to scan the two-dimensional codes, and you need to make multiple adjustments to make the shooting frame align with the two-dimensional codes. Recognizing the QR code is not very convenient to operate and

Abstract

The invention provides a method and a device for recognizing two-dimension codes. The method comprises the following steps of: recognizing all position detection graphics from an acquired picture; searching out position detection graphic triples conforming to the composition characteristics of the two-dimension codes from all the position detection graphics, wherein the composition characteristics of the two-dimension codes comprise the fact that two shortest connecting lines in the three connecting lines formed among the position detection graphics in the position detection graphic triples are vertical to each other and equal in length; determining the areas of the two-dimension codes on the basis of the searched-out position detection graphic triples; recognizing information of the two-dimension codes from the determined areas of the two-dimension codes. The method and the device for recognizing the two-dimension codes provided by the invention have the advantages that fast and batch recognition of the information contained by the multiple two-dimension codes can be realized under the condition without the help of a camera.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, and more specifically, to a two-dimensional code identification method and device. [0002] Background technique [0003] QR (Quick Response, quick response) two-dimensional code is a matrix two-dimensional code symbol invented and started to use in 1994 by Denso Wave, a subsidiary of Toyota, Japan. QR two-dimensional code not only has large information capacity, high reliability, and low cost, but also can represent various text information such as Chinese characters and images. It has strong security and anti-counterfeiting and is very convenient to use. Therefore, it soon began to be widely used all over the world. [0004] At present, the information analysis of this two-dimensional code generally uses a camera to scan the two-dimensional code picture, so as to obtain the information contained in the two-dimensional code; this traditional two-dimensional code analysis m...
