Embodiment Construction

[0037]Fig. 2 is a schematic diagram of the structure of the Chinese Sensible code. The overall structural design of the code diagram of the Han Sensible code has obvious characteristics different from the existing two-dimensional barcodes. The code map graph is a square composed of n×n modules, where n is related to the version number, and the graph storage capacity of different version numbers is different, and n is different. The Chinese Sensible code symbol is composed of image-finding graphics 1, functional information area 5, correction graphics 2, auxiliary correction graphics 3 and information coding area 4 arranged at the four vertices of a rectangular area. The information coding area includes data coding, error correction coding and Fill in information such as codewords. The image-seeking graphics in the Chinese Sensible Code have the same shape, but they are placed in different directions. As shown in Figure 2, the image-seeking graphics located in the upper right c...

Abstract

This invention discloses one two-dimensional bar image deformation correction method, which comprises the following steps: in read code image, finding images to get edit information from image finding function information area; according to edit information to get two-dimensional image space and to determine two-dimensional code image sample point coordinate; converting each data element in two-dimensional image into standard two-dimensional code image space data element.

Description

technical field [0001] The invention relates to a graphic correction method in automatic identification technology, in particular to a method for correcting distorted two-dimensional barcode graphics, which belongs to the technical field of automatic identification. Background technique [0002] Barcode technology is an emerging technology that integrates coding, printing, identification, data collection and processing developed on the basis of computer technology and information technology. The barcodes printed on commodity packaging that people see every day are ordinary one-dimensional barcodes. As an automatic identification technology, since the one-dimensional barcode came out in the early 1970s, it has been favored by people due to its advantages of fast, accurate, reliable and low production cost, and has been widely used in business, books, etc. Management, warehousing, post and telecommunications, transportation and industrial control and other fields.
