Problems solved by technology

This method has high requirements on the back-end display screen, high power consumption and cost, and is not conducive to the use of QR code scanning devices with low-resolution displays, such as OTP devices.
At present, the blind shooting scheme without shooting and framing prompts is widely used on OTP devices. For users who do not frequently operate the device, because they cannot intuitively obtain the feedback of the scanning position, the scanning result of the QR code is poor. poor experience

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...
