Embodiment 1

[0034] A three-dimensional modeling ranging method for a cable terminal tower, which is carried out in accordance with the following steps:

[0035] 1. First check the appearance of the drone’s fuselage and battery voltage, then determine the appropriate location as the landing point of the drone according to the weather conditions, and preset the specific flight trajectory according to the site clearance conditions;

[0036] 2. Record the height value between the middle cross arm and the lower cross arm of the cable terminal tower through Engong's manual flight test, and confirm the shortest flight distance between the UAV and the cable terminal tower according to the shooting angle and the position of the cable terminal platform;

[0037] 3. Use the unmanned aerial vehicle to fly at a constant speed along the circumference of the cable terminal tower, and take multiple photos. The flying height of the unmanned aerial vehicle is between the middle cross arm and the lower cross...

Abstract

A three-dimensional modeling ranging method for a cable terminal tower comprises the following steps: firstly, an unmanned aerial vehicle flies along the circumference of the cable terminal tower at a constant speed to shoot a plurality of photos; and a three-dimensional model is constructed by combining the initial flight position of the unmanned aerial vehicle, the height value between the middle cross arm and the lower cross arm of the cable terminal tower and the nearest flight distance between the unmanned aerial vehicle and the cable terminal tower, and finally the distance between cable terminal tower equipment and the distance between the cable terminal tower and the surrounding environment are determined through the constructed three-dimensional model. The design is not only accurate in distance measurement, but also simple and convenient to operate.

Description

technical field [0001] The invention belongs to the technical field of inspection and maintenance of cable terminal towers, and in particular relates to a three-dimensional modeling distance measuring method for cable terminal towers. Background technique [0002] As the junction equipment between cables and overhead lines, cable terminal towers often need to be overhauled and remodeled. At the same time, as the only terminal equipment exposed to the ground, it is plagued by surrounding trees and is also the weakest cable equipment affected by non-human influence. part. [0003] In the maintenance and renovation work, it is difficult to accurately obtain the exact position and distance of the equipment before the power outage, resulting in the tools and appliances used by the maintenance personnel after climbing the tower. , resulting in a waste of valuable electrical equipment outage time, seriously affecting work efficiency. At the same time, providing accurate line tree...
