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

Figure 3

Point cloud processing steps for a random plot: (a) plot extraction from the point cloud of the study area, (b) filtering of the point cloud to obtain the soybean points, and (c) individual row extraction by connected component algorithm and removal of less than 50-point clusters (left); computation of the individual roughness of all the points to finally calculate the canopy roughness per plot by statistic parameters from the individual roughness distribution (right).
