I just started experimenting with NDVI. I bought a IR-PRO.com INFRABLU NDVI LENS for my HERO3 black edition.
This is what I did:
- I went and did a small survey mission at a field and processed the orthomosaic in photoscan.
- I then opened up the ortho in FIJI Image and processed the NDVI.
Using NDVI_VGYRM.lut color map from http://publiclab.org/notes/cfastie/08-26-2014/new-ndvi-colormap
I noticed one thing. If I process the NDVI for a single image that made up the orthomosaic, I am getting mixed colors vs the orthomosaic which is just green mostly.
I have attached both images.
Let me know what you think.
