Introduction   Considering the increasing development of distribution network and the demand of informationization, we use UAV instead of manual means to perform power equipment inspection and improve the automation level of distribution network asset management.

    Method   Based on IOS and DJI SDK, this paper developed multi-rotor UAV patrol flight control app, automatically collected panoramic raw data according to preset flight route.Then uploaded processed panoramic image server and used DFS distributed storage to manage images. Based on Three.js, builded smooth three-dimensional panoramic scene and achieved functions like scene roaming, hotspot labeling, double-screen contrast and other functions.

    Result   The UAV control App has developed panoramic acquisition, fine inspection, rapid mapping and other modules according to the characteristics of distribution network inspection. It solved difficulties in the traditional inspection and manned helicopters in power inspection and met the needs of power grid daily inspection, fault inspection and emergency rescue. Built a distribution network panoramic management system and stored UAV inspection panoramic data in server cluster. Then intergrated and manage the gid assets and inspection panoramic data.

    Conclusion   This paper improves the efficiency of patrol image acquisition of distribution network, standardizes the data acquisition process, manages and applies massive image data and then effectively improves the automation level of information of distribution network.
