| Abstract: | Two-dimensional bar code is a newly developing method for transmitting information with large capacity and it has been seldom developed in China. This paper covers the characteristics and basic principles of the design of the codes and detailed examples of application, including an encoding method for Chinese characters. As an alternative to the use of laser scanners for bar code reader, a global solution based on a two-dimensional vision system is developed, using computer programming. The system is tested in laboratory and the results show a good success rate. |
