该读数图像自动识别系统利用CCD摄取瞄准设备读数图像经采集卡采集，运用软件的方法实现了字符识别与刻线定位，从而完成了瞄准设备方位读数的计算机动态精确自动判读。文中重点介绍了系统的硬件框架组成、软件模块结构、字符识别的连通域处理算法、刻线精确定位的内插细分算法以及系统总读数的合成。系统字符识别的正确率几乎100%，刻线定位精度达1″以上。

A new automatic imagerecognition system uses CCD to incept reading image gathered by image gathering card,achieve character recognition and reticle orientation by software way, and accomplishcomputer dynamic precise self-motion decision of azimuth. In this paper, the hardwareconstitution, software module, core process technique including connected area disposalfor character recognition, infielder subdivision arithmetic for azimuth orientation andcompound of overall reading of system are emphatically introduced. The right ratio of thetechnique is nearly 100% and the orientation precision of the reticle under a second.
