Power transmission line information extraction and safety detection method based on airborne laser radar remote sensing technology

Abstract

The invention provides a power transmission line information extraction and safety detection method based on an airborne laser radar remote sensing technology, and the power transmission line information extraction comprises the steps: deleting ground feature point clouds outside non-power lines and part of towers, and obtaining all power line point cloud data; identifying a tower and a power transmission line in the airborne laser radar remote sensing image; separating the tower point cloud from the power line point cloud so as to complete extraction of the power line point cloud. The power transmission line safety detection comprises the following steps: extracting a lowest layer of power line point cloud, calculating regular grids of ground object points, and extracting the highest point in each grid; regularly griding the airborne laser radar data points, calculating and comparing the distance between the highest point and the power transmission line point cloud with the safe distance, and judging whether dangers exist or not; and estimating the growth vigor of the tree through the GAM model, and carrying out early warning prediction. The technical problems that existing powertransmission line information extraction and safety detection are low in precision, depend on a large amount of manpower and cannot be widely popularized can be solved.

Description

technical field [0001] The invention relates to the field of power facility implementation and safety detection and evaluation, in particular to a power transmission line information extraction and safety detection method based on airborne laser radar remote sensing technology. Background technique [0002] Electric power facilities are the carrier for the smooth progress of electric power production, a key component for electric power to play a lifeline role in the national economy, and an important guarantee for accelerating economic construction and maintaining public safety. It is not only the support and driving force for the development of all walks of life, but also closely related to the production and life of the people. Among them, the power line is the most critical component in the entire power system, because only through the power line can electricity be transmitted to each household. At the same time, with the rapid growth of the national economy, the constru...
