一种图形码编码方案的研究

RESEARCH ON A GRAPHIC CODE

文中研究设计了一种易于手工表示和便于机器识别的图形码编码方案，给出了其利用图形结构描述数字字符的研究思路和设计方法．为了提高识别检错能力和便于人工记忆与手工表示，该图形码被设计成为一种有权的ｎ取ｍ码．使用现有技术，其机器识别误码率可以与条码媲美．不同职业、不同文化水平者均能容易地使用它手工表示数据．

A graphic code is studied to make manual denotation and machine recognition convenient. The research and design strategies of describing the digital characters with graphic structure are given. To improve its ability for detecting error recognition and its usability for manual denotation, the graphic code is designed as a positive weighted ( n, m ) code. By using the now available machine recognition techniques, the error rate of recognition can be reduced to the level of error rate of bar code. It is easy for everyone to denote data manually by using the code.
