Cost-effective phenotyping methods are urgently needed to advance crop genetics in order
to meet the food, fuel, and fiber demands of the coming decades. Concretely, characterizing
plot level traits in fields is of particular interest. Recent developments in high-resolution
imaging sensors for UAS (unmanned aerial systems) focused on collecting detailed
phenotypic measurements are a potential solution. We introduce canopy roughness as a
new plant plot-level trait. We tested its usability with soybean by optical data collected from …
