There is a paper out there that describes rotating a single camera OFF
the NPP. Taking two strips one from the left side of the frame and one
from the left side of the frame. Stitching these two strips together to
create the two views.
The optimizing could be done with control points down the center of the
images on distant objects.
Two panoramas stitched with different selections one to only use the
left strip and one to use the right strip.
Use Hugin or PTStitcher to stitch and use the S at the end of the O line.
# S100,600,100,800 Selection(l,r,t,b), Only pixels inside the rectangle will be used for conversion.
# Original image size is used for all image parameters
# (e.g. field-of-view) refer to the original image.
# Selection can be outside image dimension.
If using PTGui add a crop just before stitching. Do not optimize! Show
script and modify the C to a S.
