Abstract

The invention discloses a crossed crossover track distance measuring method and device based on a multi-rotor unmanned aerial vehicle. During the measurement process, a multi-rotor unmanned aerial vehicle flies at a fixed distance along two crossed crossover tracks successively; with a UAV spatial positioning technology and an IMU angle detection technology, three-dimensional spatial point cloud data of detection region space are obtained by combining distance data scanned by a two-dimensional laser radar and then a crossed crossover clearance distance curve model of an overhead transmission line is established, thereby realizing accurate measurement of the crossed crossover clearance distance of the overhead transmission line. Therefore, problems of low efficiency and precision, poor environmental adaptability and poor good real-time performance of the existing crossed crossover track inspection method can be solved. The crossed crossover track distance measuring method and device have advantages of convenient and safe operation, high measurement precision, and high efficiency.

Description

Technical field [0001] The invention relates to the technical field of electric power inspection equipment combined with the application of unmanned aerial vehicles, in particular to a cross-line distance measurement method and device based on multi-rotor unmanned aerial vehicles. Background technique [0002] Transmission lines are channels for electric energy transmission and an essential part of the power grid. When the distance between the transmission lines is too small, the wires will interfere with each other and even discharge, which will lead to accidents. Although my country has issued a series of specifications in the field of transmission line erection, transmission lines will be affected by strong winds, ground subsidence, tree growth, temperature changes, wire aging, high temperature, and sharp increase in power consumption when they cross over. The spacing between high-voltage lines will change, and there is still a risk of serious accidents. Especially in recent ...
