摘　　要：本文提出一种基于亚象素图象处理方法的游标刻度计算机读取算法,该算法使用二次曲线拟合的图像亚像素边缘定位算法,在不影响精度的情况下大大降低了对图象采集装置的要求,可使使游标自动检定设备的成本大幅度降低。This paper aims to introduce an vernier auto-reading algorithm based on sub-pixel image processing. By using sub-pixel edge detection algorithm, which is based on quadratic curve fitting. The system greatly reduce the dependency of the imaging effect upon the image gathering equipment, while keep the precision at the same time. And, as a result ,it reduce the cost of vernier autoappraising instrument.
