用静电方式套绘彩色图形／图像必须准确获取运动介质的当前位置。针对这一目的，本文给出一种基于ＣＣＤ和ＭＡＲＫ的精确定位检测方法，介绍了它的基本原理和电路结构。该电路稍作改动亦可用于其它动态检测。
Electrostatically mapping color graphics / images must accurately capture the current position of the moving medium. For this purpose, this paper presents a precise positioning detection method based on CCD and MARK, introduces its basic principle and circuit structure. The circuit is slightly modified can also be used for other dynamic detection.
