Problems solved by technology

[0003] The current two-dimensional code is a complete graphic, and sometimes some explanatory text is added outside the two-dimensional code, but this method is difficult to combine the two-dimensional code with the enterprise or product logo, and it takes up a lot of space

Embodiment 1

[0028] Table 1

[0029] FIG. 1 schematically shows the flow in Example 1. The two-dimensional code graphics (1) and logo graphics (2) encoded with information are transferred into a system or software (3) that supports image editing, and through manual editing, the two-dimensional code graphics and logo graphics are synthesized to generate a new The synthesized two-dimensional code graphic (4), the synthesized graphic can be stored, printed or transmitted. The newly generated two-dimensional code graphics can be decoded with the decoding software on the reading terminal or PC. If it cannot be decoded, it is necessary to adjust the position of the logo and / or reduce the size of the logo so that the covered data codeword and / or the bit error rate caused by the error correction code word is less than the error correction rate, as shown in Table 1, the DataMatrix code error correction rate (ECC) of the 10×10 module is 62.5%, if the bit...

Embodiment 2

[0032] In the synthesis system of two-dimensional codes and signs according to Embodiment 2 of the present invention, the synthesis method adopts automatic synthesis. The QR code can be QR Code, PDF417 and other QR codes with error correction function. Fig. 3 is a pattern of some two-dimensional codes with error correction function.

[0033] The process of embodiment 2 is the same as that of embodiment 1, except that a different two-dimensional code is changed. The principle is also that when the bit error rate caused by the data codeword and / or error correction codeword covered by the logo is lower than the correction codeword of the two-dimensional code When the error rate is higher, the composite graphics can be read. The error correction rates of all the two-dimensional codes shown in Fig. 3 have been published, and will not be listed here.

Abstract

This invention discloses one two-dimensional codes and label integration system, which comprises the following parts: one integration edit device to integrate two dimensional codes and label into one new two dimensional codes; one adjust device to adjust label size in original two dimensional codes position; one read terminal for new two dimensional codes, wherein the read terminal reads the new two dimensional codes to control the said adjust label size and original position to make the new two dimensional error rate less than error rate.

Description

technical field [0001] The invention relates to a synthesis system and method of a two-dimensional code and an identification mark. Background technique [0002] Due to the large amount of information and strong error correction capabilities, two-dimensional codes have been widely used in production management, logistics management, license management and other fields. Especially in recent years, due to the popularity of camera phones, the application of taking pictures of QR codes and reading information through mobile phones is in the ascendant around the world. Users can read the QR code on the business card with their mobile phone to obtain personal and company information; users can also read the QR code printed on the advertisement with their mobile phone to obtain the URL link of the advertisement and enter the website to obtain more information. [0003] The current two-dimensional code is a complete graphic, and sometimes some explanatory text is added outside the ...
