摘要:介绍了一个数码管显示数字仪表表盘读数的自动识别系统，在字符提取阶段，采用颜色提取的方法，使得尽管图片的字体颜

色与背景颜色相同，但只要亮度不同，也能很好的提取出字符部分。在字符分割过程中，采用增益方法识别边界，准确分割出单个字符。

并采用统计法和扫描法相结合的方法来识别数字.实验结果表明提出的方案可行，具有较强的鲁棒性.-Abstract: This paper presents a digital display digital meter dial readings of the automatic identification system, in the character extraction stage, using color extraction method, although the picture makes the font color and background color, but as long as the brightness of different, but also a very good extraction part of the characters. In the character segmentation process, the method used to identify the boundary gain, accurate segmentation of individual characters. And using statistical method and scanning method combined to identify the figures. The experimental results show that our proposal is feasible and has strong robustness.
