摘要： Introduction: The height of a grass crop can be an indicator of its seed production potential. If grasses become very tall, there is a risk of lodging and, if a grass crop is established with the purpose of producing seeds, lodging during the flowering period may result in inadequate pollination and low seed yield. Plant growth regulators (PGRs) can be applied to prevent lodging, and therefore information about crop height is relevant. In plant breeding, crop height is also a valuable trait. This study assesses a method for deriving red fescue (Festuca rubra} height from high spatial resolution (1.4 cm/pixel) 3D digital surface models of crop field trials produced via Structure from Motion (SfM) photogrammetry using aerial imagery.
