*Great! The webpage is far more informative now, putting it into sections
helps a lot. *
I’m only interested in 3D image processing, but I’ve had a look at all the
options in case they might be relevant and I hope my further questions
might help someone else. I'll look at the 3D ones later.
*--align-to-first*
*...This implies also the --use-given-order option. *
Does this mean
“Assumes you have also used –use-given-order.” If so, what would
happen if you hadn’t?
Or
“This will also set/activate/turn-on the -use-given-order option.”
---------------------------------------------------------------
*-f HFOV* *...use if EXIF info not complete*
If neither is available what happens?
---------------------------------------------------------------
*-l* *Assume linear input files are in linera colour space.*
Is the default gamma colour space?
---------------------------------------------------------------
*--distortion* *...the lens distortion...is done*
Perhaps this means “...the lens distortion *correction*...*are* done...”
Presumably if there is no distortion information or it’s invalid, this
process is just abandoned.
---------------------------------------------------------------
*-g* *gsize* ...attempt to find num control points…
i assume that the value of -num comes from -c *num *if it is set, otherwise
it is the default of 8 mentioned in that section.
---------------------------------------------------------------
*Optimisation phase*
How do “(yaw, pitch and roll) “ relate to x, y,z?
---------------------------------------------------------------
*-**m -d -i -x -y -z **Optimize field of view*
I assume one might as well always set all of -m -d -i -x -y -z in order to
optimise
everything . Unless you mean *prioritise*, in which case:
All of them will be optimised, but -X will be prioritised.
Or
-X will be optimised, the rest ignored.
