| 中文摘要: |
| 输电线路上的异物可以视为输电系统的一种潜在风险，其不仅会影响输电线路的正常供电，还会对线下的行人与车辆产生较大的威胁。基于无人机航拍输电线路图像的异物检测已经得到初步的研究，但是依然存在算法复杂度高，特征表达能力弱与需要大量人工标注等问题。因此，文中提出了一种基于多层半监督单类极限学习机(ML S2OCELM)的输电线异物检测方法，具有特征表达能力强，运算速度快、需求标注少等优点。实验证明，文中提出的方法可以在极少的正标注情况下，高效率地筛选出存在异物的航拍图像，以帮助工作人员确定出现异物的输电线位置。 |

| The foreign body in the transmission line can be regarded as a potential risk of the transmission system.The risk affects the normal power supply of the transmission line and poses a great threat to the under pedestrians and vehicles.The foreign body detection based on UAV aerial transmission line image has been preliminarily studied, but there are still some problems, such as high algorithm complexity, weak feature expression ability and large amount of manual labelling. Therefore, a foreign body detection method is proposed for the power transmission line based on multi layer semi supervised single class extreme learning machine (ML S2OCELM).The method has the advantages of strong feature expression ability, fast operation speed and less requirement labeling. Experimental results show that the method can efficiently screen out aerial images with foreign bodies under the condition of few positive labels, so as to determining the location of the power line with foreign bodies. |
