I haven't tried for images with a medium FOV, but for the images from my
peleng fisheye, it autopano doesn't work well.

One idea would be to create multiple smaller rectilinear images (lets say 4)
from the wide HFOV images. Then these could be stitched together directly.
This avoids the "reproject control points into original image" step, for
which no software exists today.
