Abstract：With the rapid development of economy, more and more high voltage transmission lines, with long transmission distance, have been built, which requires high reliability. Transmission lines, composed of overhead lines, electrical insulators, metal fittings, tower, foundation and the grounding devices, are exposed for a long time in the wild and eroded by all kinds of severe environments, which has made the transmission lines and component parts suffering serious corrosion. So, there is a huge potential risk left behind. Therefore, the detection of corrosion defects of the high voltage transmission line is of vital importance. In this paper, the author applies the UAV aerial imaDetection of Corrosion Defects for High Voltage Transmission Linesges provided by the project group to observe corrosion defects of the transmission lines under different backgrounds and analyze the features and image backgrounds of the corrosion defects. So, the author puts forward an improved semi-interactive segmentation algorithm, which relates to a quick and precise foreground extraction method applied to a group of images from similar scenario, for detecting the corrosion defects shown on the images according to the characteristics of the corrosion after the segmentation of the images. The experimental results show that the algorithm of corrosion detection proposed by the author can effectively identify the corrosion area on the transmission lines, which has improved the efficiency of maintenance.
