Abstract
The non-destructive monitoring of crop growth status with field-based or tractor-based multi- or hyperspectral sensors is a common practice in precision agriculture. The demand for flexible, easy to use, and field scale systems in super-high resolution (<20 cm) or on single plant scale is given to provide in-field variability of crop growth status for management purposes. Satellite and airborne systems are usually not able to provide the spatial and temporal resolution for such purposes within a low-cost approach. The developments in the area of Unmanned Aerial Vehicles (UAV) seem to fill exactly that niche. In this contribution, we introduce two hyperspectral frame cameras weighing less than 1 kg which can be mounted to low-weight UAVs (<3 kg). The first results of a campaign in June 2013 are presented and the derived spectra from the hyperspectral images are compared to related spectra collected with a portable spectroradiometer. The results are promising.
