Plant phenotypes refer to measurable characteristics (e.g. plant height, leaf counts, and biomass), which result from differences in genotypes and environmental conditions. Traditional phenotyping is based on manual data collection, which dramatically limits available data, and thus efficiency of matching phenotypic information with genomic data. High-throughput image based phenotyping approaches for field crops provide a non-destructive, non-invasive alternative to speed up linking associations with genotypes, leading to reduced breeding cycles for acquisition of desired traits. UAVs are potential platforms for plant phenotyping because of their capability to acquire high spatial and temporal resolution data.
