摘要
条码标尺的识别系统是数字水准仪中最重要的组成部分.基于DSP的条码标尺识别系统的设计原理与硬件电路实现方案,对条码识别的软件算法进行了研究.以DSP为核心,扩展FLASH和SRAM作为程序存储器和数据存储器,执行核心的识别处理算法,并控制前端CCD和A/D转换器的数据采集.系统以液晶显示和键盘输入作为人机交互界面.
The most important part of the digital level is the bar gauge identification system. This paper introduces the principle and the hardware design of the bar gauge identification system which is based on DSP. The algorithm of the bar gauge identification is also discussed in this paper. The DSP is the center of the system, with expanded FLASH RAM and SRAM, executes the core algorithm program, controls CCD and A/D converter as the data acquisition sub-system. The liquid crystal display and keyboard are also expanded as the interface between the users and system.
