Problems solved by technology

[0006] There are many factors that affect the normal operation of transmission lines, including the distance between transmission lines and surrounding trees and other obstacles. If the distance between transmission lines and surrounding trees and other obstacles is too close, it will cause high-voltage transmission lines and surrounding trees and other obstacles. Discharge between objects seriously affects the safety of power transmission
However, there is currently no airborne transmission line inspection system that can be used to detect the distance between the transmission line and surrounding trees and other obstacles.

Abstract

This invention relates to an airborne power transmission line inspection system based on multi-angel imaging technology, which comprises: three airborne digital cameras with observing axis in one plane and with given included angle for downward shooting, an attitude detection system for the cameras, a GPS, and a memory array. This invention has high efficiency and precision and special fit to the no man's area.

Description

technical field [0001] The invention relates to the technical field of power transmission lines, in particular to inspection and maintenance of high-voltage transmission lines, in particular to a system for inspection and detection of power transmission lines by aircraft. Background technique [0002] The overhead transmission lines of the power system are widely distributed and the lines are very long. Many of them are distributed in uninhabited mountains, such as the 500 kV ultra-high voltage transmission lines that have been built in the mountainous and hilly areas of Central China Power Grid. Most of them are far away from towns, traffic arteries, and sparsely populated. The traditional way of line maintenance and inspection relies on line operation and maintenance personnel to manually inspect the line on foot, which is not only labor-intensive, the working conditions are difficult, and the labor efficiency is low. It cannot detect or eliminate line equipment defects in ...
