An unmanned aerial vehicle-based power transmission line tree barrier hidden danger analysis method and system

Abstract

This invention relates to a method and system for analyzing tree obstruction hazards on power transmission lines based on unmanned aerial vehicles (UAVs). The method includes: collecting environmental data and basic data of the power transmission line using UAVs; dividing the power transmission line into multiple terrain analysis units based on the basic data; calculating the surrounding environment conformity index for each terrain analysis unit based on the environmental data; identifying whether the current terrain analysis unit is an abnormal terrain unit based on the surrounding environment conformity index, and matching a corresponding UAV inspection route for each identified abnormal terrain unit; collecting route data of the abnormal terrain units along the UAV inspection route; calculating the tree obstruction spatial distance conformity index based on the route data; performing tree obstruction hazard analysis based on the tree obstruction spatial distance conformity index to obtain the tree obstruction hazard level, and implementing differentiated early warning and handling strategies based on the tree obstruction hazard level.
