distortions in the panotools version was the reason why I never
investigated further years ago...

I mean to experiment with more real data and see what problems there are,
hence this ptomorph script.

It currently uses a 'Shepards' distort, which forces each point to fit
exactly. Though ImageMagick also has a polynomial distort where it applies
a 'best fit' average. This looks promising since you can pick the order of
the polynomial, and it will apply a distortion overall, just using the
control points as a guide rather than requiring an exact fit.

So there is lots of potential here.
