A Low-cost Spectral Camera for Online Vegetation and Water Identification

In general, each material reflects a different percentage of electro-magnetic (EM) radiation in each wavelength. By plotting those values with respect to the wavelength, it is possible to obtain what is called the “reflectance” of the inspected material. The reflectance is unique for each material and constitutes what can be considered a sort of spectral […]
