Example Embodiment

[0040] The present invention will be further described in detail below in conjunction with the drawings and specific implementations of the specification.

[0041] figure 1 Shows a structural block diagram of a two-dimensional code focusing display system in a specific embodiment of the present invention. The system includes a two-dimensional code image acquisition module 11, a two-dimensional code key information extraction module 12, a key information mapping module 13 and a two-dimensional code Image contour building module 14, where:

[0042] The two-dimensional code image acquisition module 11 is used to obtain a two-dimensional code image through a camera of a photographing device; the photographing device refers to a device whose display screen resolution is lower than that of the camera;

[0043] The two-dimensional code key information extraction module 12 is configured to extract the key information of the two-dimensional code in the two-dimensional code image; the key info...

Abstract

The invention discloses a two-dimension code focusing displaying method and system. Firstly, a two-dimension code image is obtained through a camera of a photographing device, then key information of a two-dimension code in the two-dimension code image is extracted, the proportional relation between the resolution ratio of the camera of the photographing device and the resolution ratio of a display area, used for displaying a photographing object outline, in a display screen is obtained, the key information of the two-dimension code image is mapped to a display screen coordinate system in proportion under a camera imaging coordinate system according to the proportional relation, and finally, outline information of the two-dimension code image is rebuilt according to the mapped key information of the two-dimension code in the two-dimension code image and is sent to the display screen for display. According to the two-dimension code focusing displaying method and system, abstract analysis is conducted on characteristic information of a scanned target, the outline information of the two-dimension code image is extracted and restored, so that real-time feedback of a framing position is achieved, dependency on high-resolution display equipment is avoided, and the two-dimension code focusing displaying method and system are particularly suitable for two-dimension code scanning equipment with a low-resolution display screen.

Description

technical field [0001] The invention belongs to the technical field of image processing, and in particular relates to a method and system for focusing and displaying a two-dimensional code. Background technique [0002] Two-dimensional barcode (2-dimensional barcode), also known as two-dimensional barcode, is a black and white pattern distributed on a plane (two-dimensional direction) with specific geometric figures according to certain rules, and is a key to all information data. In modern commercial activities, a wide range of applications can be realized, such as: product anti-counterfeiting / traceability, advertisement push, website link, data download, commodity transaction, positioning / navigation, electronic voucher, vehicle management, information transmission, business card exchange, wifi common enjoy and so on. [0003] The current two-dimensional code scanning, such as mobile phone scanning, uses a camera + high-resolution display to display the image captured by t...
