Power line inspection method of unmanned helicopter

Abstract

The invention discloses a power line inspection method of an unmanned helicopter. The power line inspection method of the unmanned helicopter includes the steps that a power line is segmented according to poles and towers, and a line inspection course of the unmanned helicopter is distributed according to the segmented power line; if the unmanned helicopter needs to hover around all the poles and towers, the intersections of all the course segments of the line inspection course are taken as hovering spots; according to the overlapping degree required when pictures are taken by a camera on the unmanned helicopter and the line inspection course, the coordinates of exposure points of the camera in the line inspection process of the unmanned helicopter are calculated; the azimuth angle and the pitch angle of a stable platform on the unmanned helicopter are calculated according to the coordinates of the exposure points of the camera; the power line is inspected. With the power line inspection method of the unmanned helicopter, the inspection preparation work of the unmanned helicopter can be completed fast and reasonably for different inspection tasks, and thus it can be guaranteed that the unmanned helicopter flies safely and reliably in the line inspection process and all sensors can effectively acquire data relevant to power transmission line equipment, and the power line inspection work can be carried out quietly conveniently by the unmanned helicopter with the power line inspection method.

Description

technical field [0001] The invention relates to the technical field of power line inspection, in particular to a power line inspection method of an unmanned helicopter. Background technique [0002] In order to effectively grasp the operation status of transmission line equipment, timely detect defects and potential safety hazards, and ensure the stable operation of the power line system, the power sector needs to conduct regular inspections of transmission lines. There are many deficiencies in the currently widely used inspection methods, such as manual inspections, operator safety issues, inspection efficiency issues, and inspection accuracy issues, and manned helicopter inspections have problems such as high costs. The unmanned helicopter multi-sensor power line inspection system uses small and medium-sized unmanned helicopters as a platform, and collects different data of line facilities by carrying sensors such as laser scanners, thermal imaging cameras, ultraviolet sca...
