摘要
提出了一种新颖的基于Zernike矩(ZMs)的直线提取算法。该算法首先是利用ZMs在局部坐标系中计算边缘点所在直线方程,然后通过坐标变换将直线方程变换到图像坐标系中,从而建立了边缘点和所在直线参数之间的一一映射关系,最后对于所求出的直线参数在参数空间对参数单元投票取阈值提取直线。实验表明,该算法速度快、精度高和抗干扰性强。
A novel algorithm of straight line detection based on Zernike moments(ZMs) was presented.The algorithm uses ZMs to establish the onetoone mapping between the edge point and the parameters of the line where the edge point lies.In the parameter space we construct a dynamic list structure,in which we only vote for the parametric cell obtained by the onetoone mapping,detect the peak and extract the lines.Experiments show that this algorithm has fast speed,high precision and robustness to noise.
