一种多圆目标的联合检测方法

本文针对现有的几种用于圆检测的方法在检测多个圆时效果不理想,提出了一种运用Hough变换和最小二乘拟合联合检测的新的圆检测方法,它是首先用改进的Hough变换进行粗检测,再用最小二乘拟合进行精确检测,既利用了Hough变换检测多个圆的优势,又利用了最小二乘拟合不能检测多个圆但检测精度高的特点,所以该方法对于多个圆的检测,具有较强的适应能力。

A Union Detecting Way of Multi-circles

At the base of comparing the ways of circles detecting, especially pointing to the detecting of multi-circles, this article uses the union of HT and the least square method to detect many circles .The precision is improved remarkably. In comparison with the base HT, the time and space is small .In the complicated picture this new method is better than RHT .And this method can be used to detect many circles in many situations.
