Three-dimensional tree reconstructions from LiDAR Scans
Global Change Research Institute of the Czech Academy of Sciences (CzechGlobe)

A unique fully-automated method for tree reconstructions from laser scan measurements (LiDAR) was developed in order to improve the quality of further studies, particularly an estimation of the total chlorophyll content of forest canopies from remote sensing data by means of coupling the leaf-level and the canopy-level radiative transfer models. The algorithm is very general and it can deal with sparse and non-uniform 3D points cloud. The program takes a cloud of 3D points (the tree scan) as input and it produces structure consisting of the trunk, branches, and foliage.
