摘要
为检测输电线路中绝缘子的缺陷,阐述了基于航拍图像中绝缘子颜色和空间距离故障的检测方法。所提方法充分考虑到前人的工作经验,在设计时引入了颜色及距离两方面因素,使算法能够综合考虑绝缘子串中多个片提供的信息,并充分利用先验信息对算法中的关键步骤予以优化。同时给出了经验值,使该算法对于多种拍照背景的实测都有良好效果。
In order to detect the defect of insulator in transmission line,the detection method based on color and space distance of insulator in aerial image is described.In this method,the previous work experience is fully considered,two factors of color and distance are introduced into the design,so that the algorithm can comprehensively consider the information provided by multiple pieces in the insulator string,and make full use of the prior information to optimize the key steps in the algorithm.At the same time,the empirical value is given,which makes the algorithm have a good effect on the actual measurement of a variety of photographic backgrounds.
