摘要 提出了一种Hough变换的亚像素椭圆检测方法.通过惯量椭圆匹配法将椭圆参数缩小到一个极小的变化范围内,然后再通过Hough变换法实现亚像素椭圆检测. In this paper, a subpixel ellipse detection method based on Hough transform is proposed. Here we reduce the parameters to a very small range by ellipse matching, and then use Hough transform to realize subpixel ellipse detection.
