A New Method for Segmenting Individual Trees from the Lidar Point Cloud

Photogrammetric Engineering & Remote Sensing, 2012
Light Detection and Ranging (lidar) has been widely applied to characterize the 3-dimensional (3D) structure of forests as it can generate 3Dpoint data with high spatial resolution and accuracy. Individual tree segmentations, usually derived from the canopy height model, are used to derive individual tree structural attributes such as tree height ...
