Two-dimensional code generation method, system and device for cylindrical surface

Abstract

The invention discloses a two-dimensional code generation method, system and device for a cylindrical surface. The method comprises the following steps: obtaining a plane two-dimensional code and obtaining the encoding content of the plane two-dimensional code through a two-dimensional code generation tool; according to the encoding content of the planar two-dimensional code, calculating the mapping relation of the planar two-dimensional code on the surface of the target cylindrical object, and then obtaining the coordinates of each pixel point of the planar two-dimensional code ; according tothe coordinates of each pixel point of the cylindrical two-dimensional code, calling a two-dimensional code generation tool to generate the cylindrical two-dimensional code. According to the size ofthe planar two-dimensional code, the size of the target cylindrical object and the distance between the scanning equipment and the surface of the target cylindrical object, regeneration is performed to obtain a cylindrical two-dimensional code which can greatly improve the recognition rate after being pasted on the surface of the cylindrical object, and the bar code provides a good help for identifying the cylindrical object, and is of great significance for food tracing and logistics tracking. The invention can be widely applied in the field of two-dimensional codes.

Description

technical field [0001] The present invention relates to the technical field of two-dimensional codes, in particular to a method, system and device for generating two-dimensional codes on cylindrical surfaces. Background technique [0002] 2-dimensional bar code (2-dimensional bar code), also known as two-dimensional code, first originated in Japan, and is a black and white graphic recording data symbol distributed in a plane (two-dimensional direction) with a specific geometric figure according to certain rules information. In the coding, the concept of "0" and "1" bit streams that constitute the internal logic basis of the computer is skillfully used, and several geometric shapes corresponding to the binary are used to represent the text and numerical information, through image input equipment or photoelectric scanning equipment Automatic reading to realize automatic processing of information. Among the two-dimensional codes, the QR code is more popular, which was invente...

Problems solved by technology

Paste ordinary two-dimensional barcodes on the surface of these objects. Although the barcode reading equipment has certain verification functions, etc., when the surface curvature of these objects is obvious, it will be difficult to read and paste the QR barcodes on the surface of these objects. read correctly
