Details about the problem
On our recent balloon mapping expedition in Qatar, we used a GoPro Hero3 Black to capture images. This camera doesn't put any lens information into the EXIF data, so post-processing the images is quite difficult.
I've tried to use photoshop's "Lens Correction" filter to remove the distortion:
but this produces sub-par results:
And even after doing this in Photoshop, creating the map proves labor intensive at best. I'd like to hear any ideas about how to combat this problem and how to correct things properly.
