Isn't the answer to the situation shown in your diagram, where there is an
isolated area of crumpling (and yes, I know it's only a diagram, but the
situation does arise in reality), to take an extra photo from directly above
the crumpled area and looking straight down on it and then force the use of
that version with an Include mask. It's probably better to avoid control
points in the actual crumpled area because of the parallax they embody.
The situation is thus analogous to taking a photomosaic of a church elevation,
where, for instance, it's vital to take images of protruding features like
buttresses and receding features like windows from straight-on and then select
those versions with masking. I think there was an early tutorial on the topic.
This sounds extraordinarily plausible.
Since the mosaic features only work on a 2D plane, any 3D features
need special handling.
I note from this tutorial:
https://panospace.wordpress.com/2010/09/19/linear-panoramas-mosaic-tutorial/
that:
"It is paramount that all CPs are on the same plane
and no currently existing CP detector known to me
meets the condition. Even small depth
errors (e.g. relief on a wall) has big impact."
I will go back and revue Terry Duell's super-successful stitch;
(email of 27/05/15 03:34; avg: 0.48, std: 0.332, max 1.98).
Terry says he (mainly) achieved this by removing bad control points;
I suspect that CPs on 3D items might well fulfil a numeric definition
of "bad".
