Canopy Roughness: A New Phenotypic Trait to Estimate Aboveground Biomass from Unmanned Aerial System

Figure 1

Schematic overview of the developed pipeline to estimate AGB by the proposed canopy roughness trait by 3D point clouds coming from RGB imagery. Canopy roughness by plot is calculated by a chain process once the point cloud of the study area is reached: (a) regularizing the point quantity of the field point cloud, (b) soil removal trough a green band filter, (c) plot and, subsequently, row extraction from the point cloud, and (d) computation of the canopy roughness using distances from points to best fitting plane.
