Research And Implementation Of A New Color Two-dimensional Code Technology

With the rapid development of Internet technology and intelligent equipment,information dissemination and identification has become an essential technology in modern society.The 2D code as now more concern,for a wide range of information dissemination means.Although it has the advantages of low cost,convenient communication,high reliability and security advantages of strong security,it needs to continually be improved.In this way can meet the needs of growing demand for information.We increase the color dimension based on the traditional two-dimensional code,and a new color 2D barcode has been proposed in this paper.Color 2D code is similar to the traditional two-dimensional code in generation and identification technology.The traditional two-dimensional code usually adopts QR encoding,QR encoding method in chaizi but using Chinese characters encoding no unified standard,and difficult,the occasional error,garbled situation.The color code design with GB18030 encoding mode of ASCII,can be more accurate and the expression of Chinese storage content data information.According to the characteristics of the color two-dimensional code,a structural concept of the color twodimensional code is designed.In the transferring process there may be interference pictures,pollution,and to identify pictures occlusion,insufficient light,first for color image noise filtering to reduce the interference caused by the wrong information.If the color printed twodimensional code,you need to first ink printing CMYK color mode to RGB color mode.Color RGB value according to the color palette color information into the data stream,decoding for storage of color in the two-dimensional code information.The color palette for color recognition area,not to determine the value of RGB.Select the 2n color palette,a color representation of N bit binary number.In this paper,256 color,16 color.4 color two-dimensional code as an example to explore.After the coding,decoding and the structure block diagram of the color twodimensional code,the color two-dimensional code system is designed and implemented through software simulation.We compared and analyzed the 256 color,16 color and 4 color two-dimensional code and the traditional color two-dimensional code,highlight that the more color of color two-dimensional code the more information storage.The innovations of this paper are as follows: 1 The design of the system of color 2D code;2 Structural improvement of color 2D code;3 Color palette selection and corresponding rules;4 Design of coding mode.The study has practical value,with high demand for information,also called information transmission technology can ensure the reliability of accuracy in recognition speed,under the conditions of greater advantage in storage and storage and other aspects of diversity,we work in this area is a useful attempt.
