Just remember that “second” Aligns use existing selected component as a base. Unregistered images or images from other components (unregistered in selected component too) will be try to align to already registered images.
I think he means that RC will try to align images, that are not part of any component yet, with the currently active component. That is quite an importand information and I did not come across it yet. So thanks for asking that!
Also a very good question that I would like to know the answer as well! My guess is that RC treats all components equally.
In addition to you initial question: Keeping the small ones, RC will probably be biased for finding an alignment and will also, if I am correct in answer 1, consider images, that are already part of a component, with a lower priority than “orphans”.
When you select any component. Other images that not in component treat as unregistered.
That’s all.
So you select desired component. And run align again (just align or after CP adjustment).
And RC will try align unregistered images with already registered in selected component.
Sometime this is enough to align all images.
Other components is just a “garbage” for us.
“Us” I mean all we usually need one component with perfectly aligned all images.
All other components just temporary data and can be deleted.
Regarding signature - don’t know. Can this count or not that I one of ReaityCapture experts. And more I working with RC more I understand that no other tools can’t make work better than RC.
No problem.
I’m in tight contact with RC and making many own researches in this area as photogrammetry expert in one of the best 3D scanning studio in Tokyo. And I try answer in areas I know really well, or ask developers first about my own thoughts.
It would be kind of helpful if such conversations would take place over the forum. For one thing some people who are interested in learning the deeper mechanisms could learn something and also the DEVs would show a bit more precense…
