Method and apparatus for analyzing canopies of trees with LIDAR data

摘要

A system and Method for analyzing a canopy of a forest by means of the analysis of the spatial uniformity of Spot Heights of LIDAR Data in a number of areas around the Crown of a Tree, where areas are smaller than the expected size of the Crown of the tree.In One embodiment, the spatial uniformity is Quantified as a Vector of canopy closure based on a specific analysis of the Heights of the LIDAR Data in frequency domain.In a particular embodiment, The Standard deviation of the frequency components in the cells of a quantity of rings Centered around the average value in a Matrix of output of FFT is used to quantify the spatial uniformity.
