基于线阵CCD的条形码识别综合实验设计

摘要

In the construction of the "Practical course of science and technology" for undergraduates,a comprehensive experiment of the barcode recognition based on the linear CCD (charge-coupled device)is designed and developed.The improvement of the measuring equipment of the barcode recognition based on the linear array CCD and the design of a series of exploratory experiments are carried out.An easy approach to decode the barcode is proposed, the content of the research-oriented experiment is expanded, and the comprehensive experiment of the barcode recognition based on the linear array CCD for university students is developed.The experiment has the features of the extensive technology,moderate difficulty,combination of theory with practice,and combination of knowledge with interest.Through the real experimental teaching practice,the effect of teaching reform is good.%在本科生"科技实践课"建设中,进行了基于线阵CCD的条形码识别综合实验的设计和开发.进行了线阵CCD识别条形码测量装置的改进和一系列探究性实验设计,提出一种简便的条形码解译方法,拓展研究型实验内容,开发了基于线阵CCD识别条形码的大学生综合实验.实验具有涵盖技术广泛、难度适中、理论与实践相结合、知识性与趣味性相结合等特点,经过实际实验教学实践,教学改革效果良好.
