Study of Real-time Processing System for Bar Code Image Based on DSP

介绍了基于DSP的条码图像实时识别系统,对原图像进行预处理后,运用模板匹配法进行图像区域查找,在原图像上分割出条码区域。DSP的强大运算功能克服了模板匹配法计算量大的缺点;DSP控制还具有电路简单、可靠、应用灵活等特性。

This paper introduces the real-time processing system for bar code images based on DSP. After pre-processing of the original image, the template matching method is utilized to region-searching, the bar code region is segmented out. The powerful computing function of DSP overcomes the shortcoming of large computing consumption for the template matching, also DSP control has features of simple circuit, reliability, and application flexibility.
