利用条形码识别技术实现智能仪器的精确定位

为实现某测量仪器的智能控制,需要对其行进的特定轨道进行位置识别,采用了现在应用十分广泛的条形码识别技术。论文简单分析了条形码的原理,按需要进行了条形码的编码,重点介绍了条形码的CCD识别。CCD识别包括CCD选型、驱动电路设计、光源设计和二值化电路设计。实践证明它能够精确、快速、可靠地完成位置信息的读取任务。

Using Bar Code Recognition Technology to Accomplish Precise Positioning

For the realization of intelligent control of a measuring instrument which moves along a particular track, we need to record the position information so we choose the bar code identification technology which now is used regularly. This paper analyzes the principle of the bar code simply and design own bar codes according to the practice, and then use the CCD to identify them. The CCD recognition actually includes choosing CCD type, driving circuit design and the binarization circuit design. The result has p...
