A LiDAR Point Cloud Column Projection Method for Estimating Zone-Specific View-Dependent Canopy Gap Fraction of Fruit Tree Canopies
View-dependent canopy gap fraction is a directional descriptor of canopy openness that provides structural information for characterizing fruit-tree canopy heterogeneity. However, existing LiDAR-based canopy characterization methods are limited in their stability for characterizing zone-specific variations in canopy oc...
