Problems solved by technology

[0003] However, the printing and placement of the current two-dimensional code is subject to certain restrictions. In the current technology, the two-dimensional code needs to be printed on a flat or nearly flat printed matter, or displayed on a flat terminal display screen, so that users can The code scanning APP in the mobile terminal can identify

Abstract

The invention discloses a method for generating and collecting a two dimension code on a surface of a cylinder-prism assembly. An original two dimension code is segmented according to a ratio of a prismatic surface and a cylindrical surface; a part, corresponding to the prismatic surface, of the two dimension code is subjected to transverse linear stretching operation; a pre-deformed two dimension code part of the prismatic surface is obtained; a part, corresponding to the cylindrical surface, of the two dimension code is subjected to transverse non-linear stretching operation; a pre-deformed two dimension code part of the cylindrical surface is obtained; a whole pre-deformed two dimension code is assembled and printed on a corresponding position of a surface of the cylinder-prism assembly; a collecting device is used for subjecting the whole pre-deformed two dimension code to image collecting operation along a direction perpendicular to a standard surface; a collected image corresponding to the whole pre-deformed two dimension code is obtained, the collected image is as same as the original two dimension code, the two dimension code can be collected and identified while a decoding module of current code scanning software remains unchanged, a range of application occasions of the two dimension code is expanded, and specifically the two dimension code can be applied to commodities having cylinder-prism assembly surfaces.

Description

technical field [0001] The invention relates to the field of printing and identification of two-dimensional codes, in particular to a method for generating and collecting two-dimensional codes on the surface of a circle-prism combination. Background technique [0002] At present, with the rapid development of the mobile Internet, the rapid popularization of mobile intelligent terminals such as smartphones and tablets under the 3G / 4G mobile network environment, and the relative maturity of the two-dimensional code encoding and decoding technology, the application of two-dimensional codes is no longer subject to the constraints of space and time. The limitation of hardware equipment thus has an increasingly far-reaching impact on people's daily life. QR codes are widely used in various industries, such as logistics, manufacturing, transportation, security, tickets and other industries. Moreover, with the rapid development of global information and communication technology, va...
