摘要
针对普通黑白QR码信息容量比较小，同时美观性不强的问题，设计了一种新型彩色QR码。该方案首先读取logo背景颜色的RGB值并求平均值，然后选取RGB值与平均值相接近的编码颜色，使彩色QR码中央的logo更加凸出；其次采用佗进制的多进制编码方案，使彩色QR码的信息容量扩大为黑白QR码的（n／2）^k倍；最后以数字编码模式为例对多进制编码方式作了简要介绍，并且对各种模式的指示符和相应版本的字符计数指示符的位数做出了规定。MATLAB仿真实验及条码容量分析表明，该彩色QR码的设计方案达到了提高视觉效果和增大二维条码信息量的目的。
Aiming at the scarcity in information capacity and aesthetic sense of black-and- white QR code, a new-type design of colored QR code has come to the reality. In this pro- gram, the average of the RGB value of logo background is taken to select the code color in which the RGB value is closest to the average value, highlighting the logo in the center of the colored QR code. Then the muhi-ary code scheme in n-ary is adopted to expend the infor- mation capacity of the colored QR code to （n/2）^k times as that of the black-and-white. Final- ly, a brief introduction to the m-ary code scheme is given, with the example of digital cod- ing, and stipulations are made for the indicators of all kinds of models and for the digit of the character count indicators of corresponding versions. MATLAB simulation experiments and code capacity analysis indicate that this design scheme of colored QR code has achieved the goals of enhancing visual effect and expending two-dimensional code capacity.
