Problems solved by technology

[0003] Although transmission line operators need to regularly carry out transmission line inspection operations, transmission line tripping accidents due to insufficient safety distance between trees and transmission lines have occurred from time to time. Conditions, different tree species, and tree growth trends are not the same. Regular inspections of transmission lines cannot fully grasp the problem of insufficient safety distance between transmission lines and trees

Abstract

The invention discloses a method for predicting a tree growth trend in a power transmission line region based on a satellite technology. The method comprises the steps of obtaining a satellite remotesensing image of the power transmission line region by utilizing an SAR satellite remote sensing technology; processing the obtained satellite image; fusing the processed image with a power grid GIS,and determining a target area image; measuring the height of the same tree at different time points in the target area image through inversion; and comparing the heights of the trees at the same placeand different time points to estimate the growth trend of the trees. A tree growth trend monitoring system based on satellite wide-area remote sensing is constructed, basic information support is provided for tree barrier inspection of the power transmission line, the alignment of the inspection line is greatly improved, and safe and stable operation of the power transmission line is ensured.

Description

technical field [0001] The application relates to the technical field of transmission line hidden danger monitoring, in particular to a method for predicting tree growth trends in transmission line areas based on satellite technology. Background technique [0002] As a channel for electric energy transmission, transmission lines are often erected between mountains and dense forests. Transmission line tripping accidents often occur due to insufficient safety distance between tree heights and transmission lines. In order to ensure the safe and stable operation of transmission lines, transmission line operators It is necessary to carry out regular inspections of transmission lines to ensure that there is a sufficient safety distance between transmission lines and trees. [0003] Although transmission line operators need to regularly carry out transmission line inspection operations, transmission line tripping accidents due to insufficient safety distance between trees and trans...
