新型亚像素圆检测算法

摘要

An improved algorithm for sub-pixel circle detection in computer vision is introduced into vision detection in this paper, according to an available theory of circle drawing of computer graphics.It can avoid multiple calculation and slow speed compared with general sub-pixel circle detection algorithms.Experiments show that the target circle can be detected in large images more fast and accurately by this method and with better anti-noisy ability.%提出了一种在计算机舰觉检测中用于亚像素圆检测的快速新算法,该算法把计算机图形学中的对圆形的生成算法理论引入到视觉检测中,避免了由于亚像素检圆检测带来的计算量大,速度慢的问题.实验表明,该检测方法不仅速度快,精度高,而且抗噪能力强.
