摘要

Based on the analysis of power transmission line patrol methods and the specific project implementation situation, a new intelligent helicopter patrol inspection system by combination of aerial imaging equipment and computer vision technology is presented. Various kinds of defects can be rapidly diagnosed, along with the defects list and the maintenance strategy report automatically generated. Working principles of defect diagnosis technology as well as the helicopter patrol system framework are emphatically described in detail. With the features of high automation, advanced technology, being fast and efficient, the helicopter patrol system which conforms to the trend of technology innovation in intelligent electric grid has a broad application prospect.
