Abstract:
A plant stress prediction system comprisinga plurality of digital cameras for taking images of a stand of vegetation at different wavelengths, a first of said cameras taking images at wavelengths associated with the absorption spectrum of chlorophyll, a second of said cameras taking images at wavelengths associated with biomass reflectance; means for computing an Algorithm Image for said stand of vegetation; and means for displaying said computed Algorithm Image, wherein said Algorithm Image is produced from digital matrix data obtained from two spectral bandpasses of less than or equal to 25 nm where a first of said two spectral bandpasses includes 680 nm and a second of said two spectral bandpasses includes 770 nm, and where the digital matrix data for the first of said two spectral bandpasses is mapped to a first color forming device and a red/far red data product obtained from the formula ((680 nm/770 nm)+128) is mapped to a second color forming device where said first and second color forming devices form different colors.
