Ultraviolet Reflectance Photography with Drone Imaging Update - A Near-UV Reflectance Index (UVRI) for Flowering Plant Imaging

Using my Multi-spectral converted Hasselblad Camera onboard the DJI Mavic 2 Pro I have been developing an experimental UV Reflectance Index program using UV-Pass Filter 

I have developed image processing codes that work with 16-bit DNG and JPG image files which creates the reflectance index that highlights the flowers, in particular those which are strongly fluorescent.

Using these test images:

The following UVRI are created:

This work is the next stage in my own research in the use of drones for remote sensing for environmental monitoring and plant health sensing, following on from developments made in the Near-Infrared which allow for NDVI map making using drone photogrammetry. 

Next steps in this work will be to expand the image processing for novel applications of the UVRI images for potential flower classification.
