Investigating correlation among near Infra red photography and NDVI index and plant stress
Joining forces the two labs of CUT have started investigating possible correlations among near infra red photographs and plant stress over crop test fields. The scope of the work is to discover whether the plant stress can be correlated and to what extend with NDVI index, which can be easily estimated with low height combined photography from UAVs. The results will be cross referenced with plants' lab analysis.
Conventional and near infra red photography took place over the test field repetitively. Geo-processing of the imagery and orthorectification was necessary for the data to become compatible. After that proper samples were masked from the orthoimagery and processed for NDVI index calculation. The NDVIs for each cell an all epochs were forwarded to the Plant Stress Physiology Group for further analysis and cross referencing with biologic analysis.
This research is based on and extends Cyprus University of Technology starting grant "Videometry from mobile platforms"
