摘要
针对条码图像采集环境不确定的特点和识别系统可移植性问题,设计一种基于ARM9的便携式PDF417二维条码终端识别系统。该系统以S3c2440为核心处理单元,嵌入式操作系统Windows ce5.0为开发平台,通过EVC编程,实现图像预处理和码字解码。移植测试结果表明,该系统能够实现PDF417码的全方位识读,识别率较高,可靠性较好。
Considering the uncertainty of bar-code acquiring environment and the portability of bar-code recognition system,a portable PDF417 2D bar-code terminal recognition system based on ARM9 is designed.S3c2440 acts as its core processing unit,and Windows ce5.0 acts as its working platform,while image preprocessing and code-word decoding can be carried out by EVC programming.Migration test results show that the system is reliable,it has a high recognition rate,and it can achieve a full range of PDF417 codes reading.
