Field-based crop phenotyping: Multispectral aerial imaging for evaluation of winter wheat emergence and spring stand
High-resolution multispectral aerial imaging was used to estimate winter wheat growth parameters. Visual ratings of emergence and spring stand were compared with data extracted from aerial images. A high correlation (r=0.86) between the ground-truth and aerial image data was observed. UAV-based sensing can be an alternative to standard methods for rapid field-based crop phenotyping.
