一种面向汉字的高压缩比彩色二维条码的设计与实现

Design and implementation of colorful two-dimensional barcode for Chinese character with high compression ratio

针对黑白二维条码信息容量不足,以及目前流行的条码标准对汉字编码的压缩比偏低,无法适应汉字大量使用的问题,参照Data Matrix码标准,通过加入汉字库并对数据编码规则、条码结构以及解码方法等进行重新设计,实现了一种具有较高信息容量且对汉字编码具有高压缩比的彩色二维条码,在pc端对其编解码进行验证,且将其与黑白二维条码性能进行对比,在总体信息容量及单位模块上所能表示的数据信息等方面,彩色二维条码均取得很好的效果.

Concerning the problem of inadequate information capacity in the black and white two-dimensional barcode and the low compression ratio for Chinese character in the black and white two-dimensional barcode that is not suitable for encoding information with large of Chinese character.Reference to the encoding standard of Data Matrix,a colorful two-dimensional barcode with both a high compression ratio for Chinese character and a relatively high information capacity is presented in this paper.This colorful two-dimensional barcode is designed under Chinese character library and the structure of this colorful two-dimensional barcode is designed.The encoding and decoding rules are designed according to frequences of Chinese characters.These encoding and decoding algorithms are verified on the computer.Comparing with the black and white barcode,this new barcode has a good effective performance on the whole information capacity and information capacity on the unit module.
