Problems solved by technology

[0003] At present, the hidden danger detection of tree barriers is mainly based on human eyes and hand-held laser ranging on the ground. However, due to the measurement angle and position relationship between people and tree barrier points, there are large errors in the detection results, and the line inspection efficiency is low.

Abstract

The invention relates to a tree obstacle information collection method for an overhead transmission line. The method comprises the following steps that: obtaining the unmanned aerial vehicle-line distance and the unmanned aerial vehicle-line angle of an unmanned aerial vehicle and the overhead transmission line, and also obtaining the unmanned aerial vehicle-tree distance and the unmanned aerial vehicle-tree angle of the unmanned aerial vehicle and the tree obstacle; according to the unmanned aerial vehicle-line distance and the unmanned aerial vehicle-line angle, controlling the unmanned aerial vehicle to fly along with the overhead transmission line; and according to the unmanned aerial vehicle-line distance, the unmanned aerial vehicle-line angle, the unmanned aerial vehicle-tree distance and the unmanned aerial vehicle-tree angle, carrying out calculation to obtain a line-tree distance between the overhead transmission line and the tree obstacle. The tree obstacle information collection method for the overhead transmission line has the advantages of high line patrol efficiency and high reliability.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a method for collecting tree block information on overhead transmission lines. Background technique [0002] Overhead transmission lines are mostly located in mountainous areas, with large areas, many trees, and many dangers. The most common problem encountered when patrolling lines is clearing tree obstacles. Trees under the canopy or in the corridor of the line that threaten the safe operation of the power supply line are called "tree obstacles". According to the statistics of China Southern Power Grid's Department of Biotechnology, about 70% of potential grid failures are caused by hidden tree barriers. The inspection and elimination of hidden tree barriers has become one of the most important tasks in inspections of transmission lines. [0003] At present, tree barrier hidden danger detection is mainly based on human eyes and hand-held laser ranging on the g...
