| 摘 要： | 专用瞄准设备智能读数系统采用普通CCD和图像采集卡,系统分辨力不高,为此采用基于矩心法的亚象素细分使刻线定位准确度大大提高.同时,针对系统图像倾斜和系统固有的刻线圆周角,进行了适当的修正,使系统最终识别准确度满足要求.

| Abstract: | The intelligentized reading system for special-pur pose collimation equipment uses common CCD and image gathering card, and the res olution of this system is low. Accordingly, sub pixel subdivision arithmet ic based on centroid is applied to improve the reticle orientation accuracy. In addition, image sloping and inherent reticle circle angle are amended. The ultimate orientation accuracy meets system's need. |
