摘要
如何在复杂背景图像中确定圆的存在,并将其准确定位,具有广泛的工程应用价值.本文通过对大量圆定位算法的研究,提出了一种利用圆形性特征在复杂背景图像中进行圆检测的新算法.经实验证明,此算法实现了复杂背景图像中圆形炮管的自动定位与分割,对于发生形变的图像,此算法仍具有较好的位移、旋转和伸缩不变性,可应用于工程中的圆检测.
How to determine the existence and the location of circle have a wider application value in engineering.Through research on many circular positioning algorithms,a new algorithm of circle detection using the characteristic of circularity in the complex background image is proposed in this paper.The method can automatically determine and segment the circular tube.When the image has a deformation,this algorithm still has a good shift,rotation and stretching invariance.It can be applied in the engineering applications of circle detection.
