Abstract

The invention discloses a commodity arc-shaped QR code conversion method, comprising the following steps: solving a commodity shape curve equation by adopting a function equation through a mathematical method according to a known special shape size of a commodity surface; obtaining a known commodity plane QR code size, a known installation position and a known commodity structure size, projectingthe commodity plane QR code to a corresponding position of a commodity special-shaped surface, and calculating the size of a commodity arc-shaped QR code; solving to obtain the size of the QR code pattern projected to the special shape of the commodity by using a commodity shape curve equation; calculating a frame size value of each region in the arc-shaped QR code pattern; and calculating arc sizes of all information areas in the commodity QR code pattern, and finally generating commodity arc QR code data. For the method for converting a planar QR code into an arc-shaped QR code provided by the invention, a planar QR code can be correspondingly formed during reading when the planar QR code is adhered to the special-shaped surface of a commodity, so that the reading accuracy of the QR codeinformation is ensured.

Description

technical field [0001] The invention relates to the fields of computer software, information technology, network technology and the like, in particular to a method for converting arc-shaped two-dimensional codes of commodities. Background technique [0002] Two-dimensional bar code (2-dimensional bar code) is a black and white pattern that is distributed on a plane (two-dimensional direction) according to certain rules to record data symbol information. It has been widely used in various fields and can be As the only information of the product, its encoding structure is compiled into a rectangular pattern by the user's own encoding algorithm. Two-dimensional code / barcode is a black and white (dark and light) graphic confirmation information distributed on a plane with specific geometric figures, which is equivalent to the distribution of logic "0" and "1" in computer language, compiled into hexadecimal counts . [0003] However, when the surface of the product is in a spec...
