Embodiment Construction

[0022] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments . Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0023] The embodiment of the present invention provides a two-dimensional code recognition method, such as figure 1 shown, including:

[0024] 101: Perform QR code positioning on the local picture of the device to determine whether the above local picture contains a QR code;

[0025] The schemes that can be used for positioning the two-dimensional code include: scan the picture on the two-dimensional code in full screen to determine wheth...

Abstract

The embodiment of the invention discloses a two-dimension code recognition method and a device, wherein the method comprises the following steps: a local image of the device is subjected to two-dimension code positioning to determine whether the local image contains a two-dimensional code, and if the local image contains the two-dimensional code, positioning, segmenting and decoding operations on the local image are carried out. The two-dimension code recognition method has the advantages that the local image is subjected to two-dimension code positioning to determine whether the local image contains the two-dimensional code, if the local image contains the two-dimensional code, the two-dimension code is recognized, and the two-dimension code image recognition can be realized without camera photographing.

Description

technical field [0001] The invention relates to the technical field of graphics and images, in particular to a two-dimensional code recognition method and equipment. Background technique [0002] QR codes were originally used in automobile manufacturers to track parts, and are now widely used in identification, anti-counterfeiting, shopping, and other aspects. Two-dimensional code, also known as two-dimensional barcode, is a pattern of bars / spaces distributed on a plane (two-dimensional direction) according to certain rules to record data symbol information with a specific geometric figure. The two-dimensional code has the characteristics of large information capacity, wide coding range, strong fault tolerance, high decoding reliability, low cost and easy production. [0003] With the development of the Internet and the popularization of mobile devices, the application of two-dimensional codes in mobile devices is also increasing. For example: at present, the identificatio...
