摘要
本文主要总结了目前几个常用的直线段检测方法。分析了当前边缘跟踪算法的不足。在此基础上,提出了一种基于Freeman链码的直线段检测方法,主要在边缘跟踪环节中对原有方法进行改进。实验表明,该算法能够快速,准确地检测直线段。
This thesis makes a general survey of some frequently used line detection algorithms and points out the deficiencies of present edge tracking algorithms.Furthermore,the author presents a line segment detection algorithm based on Freeman chain and tries to improve the edge tracking method.It proves that this algorithm can detect the line segment rapidly and accurately.
