Problems solved by technology

[0004] In the daily use of two-dimensional codes, poor recognition often occurs in certain environments. For example, when the position detection pattern of the two-dimensional code is slightly stained or the brightness is weak, it is often impossible to accurately identify the two-dimensional code. Position detection graphics, resulting in the inability to locate the QR code, thus failing to recognize the QR code

Abstract

The embodiment of the invention provides a QR code positioning method and device. The method comprises the steps of determining the center position of a suspected position pattern in a QR code image containing first type pixels and second type pixels according to the first type pixels, the second type pixels, the sequence arrangement proportion of the first type pixels, identifying a correspondingsuspected position detection pattern according to the determined center position of the suspected position detection pattern, determining a pattern conforming to QR code positioning rules from the identified suspected position detection pattern, and taking the determined pattern as position detection pattern of the QR code image.

Description

technical field [0001] The present application relates to the field of image processing, in particular to a two-dimensional code positioning method and device. Background technique [0002] Two-dimensional code, also known as two-dimensional barcode, records data symbol information through a pattern formed by a specific geometric figure distributed on a plane (two-dimensional direction) according to certain rules. Compared with traditional barcodes, two-dimensional codes have the characteristics of high information capacity, strong error correction ability, and high decoding reliability. At the same time, they also have the advantages of low cost and easy production. Therefore, two-dimensional codes have been widely used in many fields, for example, payment fields, identity authentication fields, and the like. [0003] When using a two-dimensional code, after scanning the two-dimensional code, the two-dimensional code needs to be recognized to obtain the data symbol informa...
