摘要
基于Hough变换的基本理论及目前的改进算法,针对Hough变换所存在的参数峰值不明显、存储空间大及计算速度慢等不足,提出了一种改进的随机Hough变换,可实现由长到短逐次提取线段,并给出了线段起始点和终止点的计算方法。实验证明了该改进算法的有效性。
Based on the basic theories and improved algorithm of Hough transform, an improved random Hough transform algorithm is proposed to make up for the deficiencies of the traditional one. By it, the line segment can be extracted from the long to the short one by one, and the start-point and the end-point algorithm are also obtained. And, the validity of the improved method is proved by the experiment.
