AbstractThis research evaluated the capability of an unmanned aerial vehicle (UAVs) –based system to monitor the plant heights of several wheat, barley and triticale field trials over time, by applying a customised object-based image analysis algorithm to the digital surface models created with the structure-from-motion technique. Comparisons between UAV-based and ground-based measurements over time reported an overall coefficient of determination (R2) of 0.917 and an average root mean square (RMS) error of 0.10 m. With a target of field phenotyping, a ranking of genotypes in term of plant heights and crop growth was accurately provided, which can facilitate the decision making process in cereal breeding programs.
