| 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。

| Abstract: | In real time computer vision detection and control systems,circles,whose images are ellipses,are usually served as earmarks with their centers as feature poets.Quickly extracting image coordination of these centers is the key to the real time of systems.In this paper,a new method is pur forward to calculate the center of the ellipse based on geometric features.The experimental results are given to show that this method is very effective. |
