分析了传统Hough变换检测圆中一对多的映射关系导致性能下降的问题,总结了经典的Hough算法和其他研究人员提出的其它改进算法后,提出了采用圆的几何特征,利用圆周上两个对称点的中心为圆心,先检测出圆的圆心,然后检测半径的方法来检测圆.实验及分析证实该方法降低了Hough变换的转换的维度,比传统的Hough变换性能有较大的提高.

After analyzing the problems in the traditional methods to detect circle by one-to-many relationship that leads to performance degradation and summarizing the classical Hough transforms and other improved algorithms proposed by other researchers,an algorithm is proposed,which uses circle's basic geometric features the center of two symmetrical points in circle is the circle center of the circle to detect the circle center firstly and then detect the radius so that decrease the dimension of the transform.Finally the experiment and analysis show that the performance improved.
