【摘要】 为了实现复杂背景中准确识别圆形,本文提出了一种基于线段分割的圆识别算法.首先,在Canny检测的基础上,利用单像素边缘跟踪算法提取边缘;其次,将边缘分割为多条小线段,并利用相邻两条线段的夹角判断是否构成圆弧;最后通过最小二乘法完成圆识别.实验表明,本文算法准确、快速、鲁棒.更多还原

【Abstract】 In order to accurately recognize circles in complex images,the paper put forward a novel method based on line segment. First,it got edges by single-pixel edge tracking based on Canny detector. Second,it segmented the edge into many short lines and decided it whether formed circular arc or not by the angle between two adjacent lines. Last,it recognized circles by least square method. The experimental results show that our method is accurate,fast and robust.更多还原
