What I want to do
Explore mapping with lightweight PL Mobius Infragram and low-lift, low altitude UAVs (like Parrot AR.Drone 2.0).
My attempt and results
Mounted PL Mobius Infragram Point and Shoot on Parrot AR.Drone 2.0 using orange rubber bands.
Flew initial low altitude test. Used paid license version of PTLens to apply fisheye correction and crop the images.
Example Before
After
Used Adobe PS to make a panorama from the fisheye corrected, cropped infrablue images.
I stitched a couple of the images in Mapknitter. However, the very low altitude images, require zooming all the way in.
I stitched five of the images in Mapknitter. After initial null exports, Jeff Warren revised the resolution from 0.39 cm/pixel to 1 cm/pixel, which led to successful export. As noted above, the very low altitude images, require zooming all the way in.
Cropped, then used Ned Horning's Fiji Photomonitoring plugin to process the infrablue panorama to NDVI.
Floating Point
Color using NDVIBlu2Red.lut
Questions and next steps
Get the gps waypoint capability working again, explore niche where this combination of gear makes sense.
Why I'm interested
The lightweight form factor of PL Mobius Infragram Point and Shoot allows use of it with low-lift UAVs. Together with ability to correct fisheye effect, makes for another (albeit limited niche) aerial mapping tool in the toolbox.

The lens distortion correction and NDVI look great!

Thanks Stewart, I appreciated your suggestions on correcting the distortions.

This looks really good, how do i translate the PTLens stuff into GIMP or BIMP, like the folks in Maine are posting about?

Haven't tried it, but this site discusses how to Correct Fisheye in GIMP http://classroom.synonym.com/correct-fisheye-gimp-19646.html
