Two perhaps dead-end suggestions. First, if you can get the lens
specifications, you could probably use GIS ortho-rectification software to
take out the stretch. Alternately, you can designate the absolute positions
of specific points in your photos an the software will "rubber sheet" the
image back to the real world. If you have a GIS guru available (s)he should
be able to help you. ALternately, you might contact the camera
manufaxcturer. They might have software that could post-process your
images, essentially doing what the camera does automatically.
