摘要

systems for analyzing a canopy of an area of a forest from data handling and for estimating a number of trees in a forest area, and, computer readable storage media describes a system and method for analyzing a forest canopy by Spatial uniformity analysis of data point heights deal in numerous areas surrounding a tree top, where areas are smaller than the expected size of the tree crown. In one embodiment, spatial uniformity is qualified as a canopy closure value based on an analysis of data point heights dealing in a frequency domain. In one particular embodiment, the standard deviation of frequency components in the cells of numerous rings centered around the mean value in an fft output matrix is used to quantify spatial uniformity.
