基于CPLD+DSP的红外条码图像采集及识别系统设计

Design of Infrared Barcode Image Capturing and Recognizing System Based on CPLD+DSP

论文介绍了以CCD作为图像传感器、以CPLD作为图像采集系统的控制核心、以DSP作为基本图像处理单元的红外条码图像自动采集及识别系统设计。系统完成了图像的快速采集、存储及数据处理。文章不仅对系统的硬件设计和软件设计进行了讨论,而且对应用的算法也进行了介绍。

Infrared barcode image capturing and recognizing system is introduced in the paper. In the system, CCD is used to capture image, and CPLD to access fast timing closure, DSP is used as image processing unit. Thus high speed image capturing, storing ＂and processing is achieved. This paper discusses hardware and software design;and the preferred algorithm is also introduced.
