Classification of high-voltage power line structures in low density ALS data acquired over broad non-urban areas

Jean-Romain Roussel, Alexis Achim, David Auty
2021 PeerJ Computer Science  
This work will help further the automated detection capacity of power line structures, which had previously been limited to high density point clouds in small, urbanised areas.  ...  Processing ALS data over large areas for forest resource estimation and ecological assessments requires efficient algorithms to filter out some points from the raw data and remove human-made structures  ...  In practice, however, such a method has important limitations, especially in broad, non-urban and low-density coverage.  ...
