摘　　要：基于Canny算法基本原理,针对拉线塔拉线边缘检测传统算法识别精度差、响应速度慢、误检率高等缺点,提出了改进后的Canny-Cauchy算法。此算法采用自适应中值滤波对椒盐噪声进行处理,使用柯西分布的一阶导数作为边缘检测函数。参考常规边缘检测三准则进行了理论分析,并基于BSDS500数据集进行了检测实验。实验表明Canny-Cauchy算法对噪声的抑制能力、对真实边缘的响应能力以及对边缘检测的连续性相比其他算法显著提升。Based on the basic principle of Canny algorithm,this word proposed a modified Canny-Cauchy algorithm for the shortcomings of poor recognition accuracy,slow response speed,high false detection rate,etc.with respect to the conventional transmission guyed tower edge detection algorithms.This algorithm adopts adaptive median filtering for pretzel noise,uses the first-order derivative of the Cauchy distribution as the edge detection function.Theoretical analysis with reference to the conventional three criteria for edge detection was performed,and detection experiments were carried out based on the BSDS500 dataset,showing that the Canny-Cauchy algorithm is vastly superior to other algorithms in the suppression of noise,the response to real edges,and the continuity of edge detection.
