Abstract

The present invention proposes a power inspection method, device and electronic equipment based on an unmanned aerial vehicle, which relates to the field of unmanned aerial vehicles, wherein the method includes obtaining a three-dimensional point cloud of a target power line area; performing point cloud segmentation and aggregation on the three-dimensional point cloud classify the center points of multiple target insulators; classify multiple target insulators according to the preset classification rules to obtain multiple classification groups; based on the midpoint of the line connecting the center points of two insulators in each classification group and the The center point of the tower pole that belongs to the tower pole that is on the same level as the midpoint determines the shooting point of each classification group by the drone; the inspection path is generated based on the shooting points of each classification group. Through 3D point cloud reconstruction and segmentation, the UAV can perceive and recognize the environment, and finally plan a reasonable inspection path, which saves manpower, improves efficiency, realizes the autonomous inspection of UAVs, and alleviates the existing technology. There are problems of low inspection efficiency and redundant staffing.

Description

technical field [0001] The present invention relates to the technical field of unmanned aerial vehicles, in particular, to a power inspection method, device and electronic equipment based on unmanned aerial vehicles. Background technique [0002] In recent years, power line inspection has received a lot of attention as a widespread application of UAVs. With the dramatic increase in the demand for electricity in life and industry, effective and reliable monitoring of potential threats to power lines has become critical. Therefore, in order to ensure the safe operation of the power grid, regular power inspections are required. [0003] At present, in the prior art, the unmanned aerial vehicle in the process of detecting the power line is manually operated. The operator needs to always pay attention to the safe distance between the drone and the power line, and take pictures of the inspection points of interest. Humans are still the subject of this mission, while drones are ...
