摘　　要：输电线处于自然环境中,背景通常为植被和田野,而配电线布设于城镇街道,建筑纹理、屋檐屋顶和其他线路等都会对配电线检测造成极大影响,常用的输电线检测方法无法有效去除这些环境干扰。文中提出了一种改进的分段灰度变换增强方法,先消除干扰,再通过自适应阈值的Canny算子结合形态学处理方法,进一步加强配电线特征。最后提出了基于区域筛选的Hough变换,在提取得到的配电线区域中确定配电线目标。实验结果表明,提出方法能够在复杂干扰环境下实现配电线检测,并且提高了精度和效率。The transmission line is in the natural environment,the background is usually vegetation and field,and the distribution line is located in the urban street,building texture,roof and other lines will have a great impact on the distribution line detection,the commonly used transmission line detection methods can not effectively remove these environmental interference.In this paper,an improved segmented gray⁃scale transform enhancement method is proposed to eliminate the interference first.Then,the characteristics of distribution lines are further enhanced by Canny operator with adaptive threshold and morphological processing method.Finally,Hough transform based on area screening is proposed to determine the distribution line target in the extracted distribution line region.The experimental results show that this method can achieve distribution line detection in complex interference environment,and improve the accuracy and efficiency.
