System for detecting transmission towers and lines based on point cloud data

Abstract

The invention provides a system for detecting transmission tower and line based on point cloud data, comprising an unmanned aerial vehicle acquisition system, wherein the unmanned aerial vehicle acquisition system is equipped with an AS-100. Based on the point cloud trajectory captured by UAV during flight, the point cloud map of transmission tower and line is constructed according to the point cloud trajectory, and the video data is collected by UAV during flight. A point cloud preprocessing device preprocesses the acquired point cloud data to obtain the ground laser point cloud, the vegetation laser point cloud and the transmission line laser point cloud data respectively; The statistical analysis module optimizes the transmission tower location based on the section, and carries out statistical analysis on the line indexes according to the coordinate data of transmission tower location and the section data of transmission tower foundation; Three-dimensional modeling module, by processing the point cloud data and video data collected by the unmanned aerial vehicle (UAV) mounted system to generate quasi-DOM, DEM, combined with the classified point cloud, to achieve the three-dimensional modeling of transmission tower and transmission line.

Description

technical field [0001] The invention relates to the field of surveying and mapping, in particular to a system for detecting transmission towers and lines based on point cloud data. Background technique [0002] In recent years, with the rapid development of China's economic construction, the demand for electricity has increased sharply, and the demand for power grid construction has become increasingly strong. At the same time, in the face of the huge power network that has been built, how to effectively manage it to ensure the normal operation of the power grid and ensure the safe transmission of power is even more important. A power outage not only brings huge losses to the economic benefits of power grid operating companies, but also has a serious impact on power users and even the entire society. [0003] Traditional line management, optimization, and power line inspection mostly use manual surveying and mapping or aerial photogrammetry, which has the following three di...

Problems solved by technology

[0004] 1. The data is not intuitive, the accuracy is low, and the degree of reuse is not high;

[0005] 2. The operation intensity is high and the operation cycle is long;

[0006] 3. It is difficult to work in areas with complex terrain

[0007] In addition, the existing drone inspection technology only uses a single drone to carry the task load to perform tasks, and at the same time only uses the drone for remote photography. Is there any abnormality
