Embodiment Construction

[0038] Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0039] see figure 1 , a three-dimensional visualization processing method for an ultra-high voltage transmission line, comprising the following steps:

[0040] S1: The aircraft carries a laser radar measurement system to inspect the transmission line. The laser radar measurement system includes a GPS positioning system, a laser scanning ranging system, and an inertial navigation system to obtain digital image data and laser point clouds along the transmission line. data and GPS data;

[0041] S2: Filter the laser point cloud data, and combine the GPS data for classification and calculation, and generate a digital elevation model (DEM) that can confirm the details of the surface shape;

[0042] Use the laser point cloud data as a reference to build a 3D model of ground objects, such as 3D models of lines, buildings, and vegetation;

[0043] P...

Abstract

The invention provides a three-dimensional visual processing method of an extra high voltage transmission line, which comprises the following steps: synchronously acquiring laser point cloud data and digital image data along a transmission line corridor through an airborne laser radar measurement system, and carrying out three-dimensional visual processing and professional analysis in combination of line design parameters and operating parameters after data processing and three-dimensional modeling so as to provide an efficient means for the maintenance and the management of the transmission line of an electric power enterprise. The invention further provides a three-dimensional visual processing system for the extra high voltage transmission line, which comprises a three-dimensional data generation module and a three-dimensional data visual operation module, wherein the three-dimensional data generation module is used for receiving digital image data and laser point cloud data obtained by the laser radar measurement system and generating the three-dimensional scene of the transmission line corridor; and the three-dimensional data visual operation module is used for carrying out three-dimensional visual operation on the three-dimensional data of the transmission line corridor.

Description

technical field [0001] The invention belongs to the technical field of transmission line monitoring. Background technique [0002] Transmission lines, especially ultra-high voltage transmission lines, usually pass through inaccessible high mountains and harsh natural environments. Bee pests, snake pests and other wild animals also pose a serious threat to the lives of employees. At the same time, some The line cannot be observed manually due to trees and mountains. Therefore, the inspection and monitoring of ultra-high voltage transmission lines has always been a difficult problem for electric workers and electric power companies. [0003] Especially in Southwest my country, the area where the ultra-high voltage transmission line passes is located in the Dashan Mountains, with steep and broken terrain and criss-cross ravines. The branches are distributed on both sides of the Yangtze River, making the terrain even more steep and broken, with ravines and ravines, and a huge di...
