Project Background
The 2021 Davidson Prize winner, LeafSpec, is the first touch-based high resolution hyperspectral leaf scanner of its type. Instead of measuring the leaf’s averaged spectrum, this project will explore a new algorithm to utilize both spatial and spectral information in the hyperspectral leaf image for more accurate nitrogen assessment. A fully automated robot system will also be further developed to operate this touch-based leaf scanner in the field.
