Abstract
A method for retrieving heights of densely-covered forest canopies near power transmission lines includes: acquiring ICESat-2 LiDAR data, JL-1 image data, auxiliary data and three-dimensional information data about the power transmission lines within a target area; carrying out image preprocessing on a JL-1 image to generate a first image; screening the ICESat-2 LiDAR data according to a screening rule to obtain high-quality laser tree height data; by employing the first image, the high-quality laser tree height data and the auxiliary data, training a neural network model for retrieving a forest tree height according to an optical image and the auxiliary data; by employing the neural network model, generating a height distribution map of densely-covered trees in the target area; and calculating a height difference between a tree and a power transmission line nearest the tree to generate a hidden danger troubleshooting theme map.
