基于图像融合的输电线路覆冰边缘检测

输电线路覆冰一直是电力系统迫切希望解决的重要问题之一。针对输电线路覆冰边缘检测,提出了一种基于图像融合技术的方法对输电线路覆冰状态进行判定。对输电线路进行边缘检测是通过图像预处理、Canny算子的边缘检测、形态学边缘检测以及像素级图像融合等方法实现的。实验仿真表明:融合后的图像边缘能够取各自的优势,使边缘检测效果更好。

Edge Detection of Transmission Line Based on Image Fusion

Ice coating on transmission lines has always been one of the most important issues that the power system is eager to solve. Aiming at the detection of ice-covered edge of transmission line, a method based on image fusion technology is proposed to judge the ice-covered state of transmission line. Edge detection of transmission lines is achieved by image preprocessing, edge detection of Canny operator, morphological edge detection, and pixel-level image fusion. The experimental simulation shows that the edge of the image after fusion can take their own advantages and make the edge detection effect better.
