Problems solved by technology

[0007] It is a good choice to use barcodes to record the unified identification of publication information. However, due to the large amount of publication information identification data of each publishing organization, the classification methods are different, and it is difficult to reach the standard in a short period of time, and the content of recorded information is also quite different. Large, the data capacity of the barcode is limited, and the existing barcode technology cannot meet the relevant applications

Embodiment Construction

[0035] The present invention will be further described below in conjunction with the drawings and specific embodiments.

[0036] Such as Figure 5 As shown, the two-dimensional barcode system with large information capacity provided by the present invention is composed of a barcode generating device 22, a barcode recognition device 25, an image processing device 24, a template management device 21, and a foreign character device 23.

[0037] The barcode generating device 22 is used to generate barcodes, that is, to convert the information input by the user into a barcode picture or a barcode foreign word for use in typesetting and printing output software. The generation control information is provided by the template management device 21, and the barcode generating device provides external barcode generation Interface 26.

[0038] The barcode recognition device 25 is used for barcode recognition, that is, provides a barcode recognition service for input images through a barcode rec...

Abstract

The invention relates to a two dimensional bar code with large information capacity and a system, belonging to the field of the information publication. Through building the two dimensional bar code matching with the character feature, the invention realizes the application suitable for the length uncertainty of the bar code and the information revivification based on the template by a plurality of continuous two dimensional bar codes. The way adopting the two dimensional bar code is used to record the extended information code, wherein the code way is simple and easy to extend. The two dimensional bar code of the invention can conveniently bear the extended information content with high fault tolerant ratio, simple making and using, which can be used matching with the characteristic easyto extend of the bar code template and has wide application foreground in the field of the information publication.

Description

Technical field [0001] The invention belongs to the field of information publishing, and specifically relates to a two-dimensional bar code system with large information capacity. Background technique [0002] With the improvement of the computing power of barcode recognition terminals and the expansion of the amount of information carried by barcodes, two-dimensional barcodes have been greatly developed and applied in recent years by virtue of their advantages over the information of one-dimensional barcodes. Due to the further increase in the amount of information contained in barcodes, some new technologies have emerged to solve related problems, such as the Chinese patent application "Two-dimensional Barcode Color Information Overlay" (200610080444.6). This method generates a multiple Color two-dimensional bar code diagram of layer color information. When decoding, the information in each layer is read through different color channels to increase the information capacity of ...
