I am trying to get a NDVI image from an RGB + NIR image captured by a modified Cannon S110 camera bought from Event38 along with a 3DR Iris+ drone link

The image captured with the camera looks like this Image captured with modified camera

I have previously experimented with python and rasterio and successfully calculated an NDVI image from 2 images (one RGB and one NIR).

Researching around the internet I have found this to be achievable from one image. However I haven't found any image manipulation library to be helpful.

Can someone with more experience in this offer any guidance? Any programming language is welcome.


This tutorial might be interesting for you.

You can access the indivudal bands (you need red and NIR) and calculate the NDVI from that.
