摘要:

提出了一种针对嵌入式系统的字符识别方法。介绍了一种基于ARM9处理器和嵌入式Linux的字符图像采集与识别系统。该系统采用嵌入式Linux操作系统,图像预处理和字符识别的软件开发可以脱离硬件。通过开发不同的识别软件,系统可应用于名片识别、二维条码识别、纸币序列号识别等多种字符识别的场合,提高了通用性。

关键词: 字符识别, ARM, Linux, 接触式图像传感器, CPLD

Abstract:

A character image acquisition and recognition system based on the ARM microprocessor and embedded Linux OS is introduced. The image preprocessing and character recognition software which works on the embedded Linux OS can divorce from the hardware. This system can be widely applied in the calling card, barcode, serial numbers recognition and other character recognition situations and its universality is greatly improved.

Key words: character recognition, ARM, Linux, contact image sensor, CPLD
