The estimation of wheat yield combined with UAV canopy spectral and volumetric data

Estimating wheat yield accurately is crucial for efficient agricultural manage- ment. While canopy spectral information is widely used for this purpose, the in- corporation of canopy volumetric features (CVFs) remains underexplored. This study bridges this gap by utilizing unmanned aerial vehicle (UAV) multispec- tral imaging to capture images and elevation data of wheat at key developmental stages—gestation and flowering stages. We innovatively leveraged the elevation differences between...
