Abstract
System and method for remotely determining a chlorophyll concentration in crops present in agricultural fields, wherein a chlorophyll related vegetation index is combined with a water related vegetation index to determine a chlorophyll concentration. Further embodiments for the combination of remote and local sensing are included as well as the determination of measurement regions for that goal are disclosed.
Claims18
A computer-implemented method for remotely determining a chlorophyll concentration of a crop in an agricultural field, wherein the method comprises steps of:
- a) receiving remote spectral data from a plurality of wavelengths of the agricultural field, wherein the plurality of wavelengths comprises at least one wavelength from a water absorption band and at least one from a chlorophyll absorption band,
- b) generating a first index, wherein the first index is a chlorophyll related vegetation index based on the at least one chlorophyll absorption band of said spectral data,
- c) generating a second index, wherein the second index is a water related vegetation index based on the at least one water absorption band of said spectral data, and
- d) determining the chlorophyll concentration of the crop based on the chlorophyll related vegetation index and the water related vegetation index.
