输电线路巡检是提高配电网运行可靠性的一项重要工作。这项任务可以使用无人驾驶飞机以低成本的方式完成。在本研究中，我们检验了使用基本图像处理方法对无人机（UAV）获取的电力线图像数据的有效性。在考虑到检查输电线路的目的下，为目前的工作组装了特定的无人机。为了检测视频图像上线条的位置，提出了两种不同的预处理方法。这两种方法都在现实世界中进行了测试，每种情况下的图像背景都具有不均匀纹理的特征，即自然地形在某些地方崎岖不平，树木繁茂的土地在其他地方，或者道路与空中电力线呈现相同的色调。我们研究了折线的情况，其中方法导致在电力线中断之前和之后成功检测电力线。所提出的工作为输电线路的检测提供了一种可靠、低成本的方法，是检测电缆故障发生位置的有效方法。
The inspection of power transmission lines is an important task that enhances the reliability of Electricity Distribution Network Operators. This task can be performed in a low-cost way using unmanned aircrafts. At the present study, we examine the effectiveness of using basic image processing methods on image data of the power lines acquired by an unmanned aerial vehicle (UAV). The specific UAV was assembled for the present work under the considerations that arise from the purpose of the inspection of power transmission lines. Two methodologies are proposed differing on the preprocessing required in order to detect the location of the lines on the video images. Both proposed methodologies were tested in real-world cases, with the image background in each case to be characterized of non-uniform texture, i.e., the natural terrain is rugged at some locations, wooded land at some other or it is road that appears at the same hue as the aerial power lines. We examined the case of a broken line where the methodologies result in successful detection of the power lines before and after the discontinuity of the power line. The proposed work offers a robust and low-cost way for the inspection of power transmission lines and so an effective way to detect the location where a cable fault has occurred.
