【摘要】 在计算机视觉实时检测和控制系统中，经常以圆（成像后为椭圆）作为标志，并以其中心为特征点，特征点象坐标的快速求取对于保证系统检测和控制的实时性至关重要。本文提出了基于几何特性的椭圆中心象坐标快速求取方法，实验证明此方法是十分有效的。更多还原

【Abstract】 In real the computer vision detection and cotrol systems, circles, whose images are ellipses, areusually served as earmarks with their centers as feature points. Quickly extracting image coordination of thesecenters is the key to the real time of systems In this paper, a new method is put forward to calculate the centerof the ellipse based on geometric features.The experimental results are given to show that this method is very effective.更多还原
