Tree barrier hidden danger rapid detection method based on vegetation three-dimensional convex hull and terminal

Abstract

The invention discloses a tree barrier hidden danger rapid detection method based on a vegetation three-dimensional convex hull and a terminal. The method comprises the steps that ground points in a power transmission line are filtered based on a cloth filtering algorithm; a power line point cloud is extracted from the power transmission line laser point cloud data of which the ground points are filtered out; vegetation point cloud in the power transmission line laser point cloud data is extracted; three-dimensional reconstruction is performed on the single power line to obtain a vectorizationmodel of the single power line; and the vegetation three-dimensional convex hull is generated through the vegetation point cloud, the distance between the vegetation three-dimensional convex hull andthe power line vector is calculated, tree barrier hidden danger analysis is conducted according to the distance, and a tree barrier hidden danger analysis result is obtained. According to the methodfor calculating the distance between the power line vector and the vegetation three-dimensional convex hull, the calculation amount of the tree line distance is greatly reduced, and the tree barrier hidden danger detection efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of electric power inspection, in particular to a method for quickly detecting hidden dangers of tree barriers on transmission lines, in particular to a method for detecting hidden dangers of tree barriers based on three-dimensional convex hull points of vegetation. Background technique [0002] With the rapid development and comprehensive deepening of national economic construction, the scale of power system construction is expanding day by day, and the environment and structure of power grid erection are more complex. The monitoring of power grid operation is particularly important. presented new challenges. Transmission lines have the characteristics of high transmission voltage, long distance, complex and changeable environment, and many open-air hazards. After the transmission line is erected, its allowable maximum sag and maximum wind deflection are limited within a certain range. However, the vegetat...
