Snapshot Hyperspectral Imaging for Field Data Acquisition in Agriculture (in Raspberry Plantation)

A snapshot spectral camera with more than 100 spectral channels was used and tested. A native snapshot imaging spectrometer captures all spectra and the entire image at the same time without any time delay. It enables this imaging system to capture motion pictures and producing hyperspectral videos. In our horticulture study a snapshot camera was applied to spectrally document, map and characterize a raspberry plantation under differently coloured shade nets to analyse usability, flexibility and to record spectro-phenological parameters. Leading raspberry producers are located in Eastern Europe and contribute at least 80% of the world's raspberry production (FAOSTAT, 2016). Due to agricultural climate change scenarios raspberry plantations are at risk because evapotranspiration will be challenged by solar radiation and temperature changes. We concluded that spectral field data acquisition and length of data evaluation could be significantly reduced by snapshot spectral imaging.
