Abstract

The invention discloses a two-dimensional code identification method which comprises the steps that arraying directions of identification head code points, distances among the identification head code points, mass center positions of the identification head code points, a position of a dominant straight line, and the number of code elements in a content data component in a code word block are confirmed; a virtual state box of the whole code word block is obtained according to the arraying directions of the identification head code points, the distances among the identification head code points, the mass center positions of the identification head code points, the position of the dominant straight line, and the number of the code elements in the content data component in the code word block; a coded value indicated by each code element of the content data component is obtained according to the virtual state box of the whole code word block, and combined according to a set sequence; and coded information of the whole code word block is obtained. Correspondingly, the invention further discloses a two-dimensional code identification device, a two-dimensional code reading method and a two-dimensional code micro platemaking method. According to an approximate position of a locating code word block of the dominant straight line, an identification algorithm is simple, and an identification rate is high.

Description

technical field

[0001] The invention relates to the technical field of encoding and identification thereof, in particular to a method for encoding, identifying, reading and miniature plate-making of a two-dimensional code. Background technique

[0002] With the continuous innovation of two-dimensional code recognition technology, invisible two-dimensional code technology also appears. For example, the Optical Identification (OID, Optical Identification) code for audiobooks was designed by companies such as Songhan and Lingyang in Taiwan. The OID code is essentially a completely invisible code. The OID code is deeply used in the audiobook field of preschool education popular.

[0003] Now the invisible two-dimensional code is just a single infrared two-dimensional code or ultraviolet two-dimensional code, which needs to locate the code position in audio albums, valuable tickets (tickets, stamps, stocks, sports, performances or exhibition tickets), audiobooks for the blind, e...
