So, first of all, thanks to everyone for their previous help in the setup for scanning branches (https://support.capturingreality.com/hc/en-us/community/posts/115002960132-Setup-for-scanning-branches). Despite my poor use of green screens, I think it came out pretty well.
As an example, for one branch, I took 49 photos total. 16 from an outer ring, 16 from a closer ring, and the rest were closeups (I tried to not move too much between shots). RC aligned 34 of them. Most of those that didn't align in the main component were closeups. This makes some sense, as closeups of branches don't really have many distinguishing features. I even had a hard time manually adding CPs (which I gave up on), as I couldn't tell what was what.
As a result of the unaligned photos (I think), the resulting model has branch sections that are discontinuous (see below).
I'd like to improve my process. One critical thing seems to be to enable the closeups to align more often. As I'm only interested in the structure of the branch, I am able to add colored tags and otherwise to the branch sections in order to help RC align closeups.
So the question is: what would be the most effective "targets" I could add to the branch sections? Does RC use color in it's matching algorithm? If so, then I could add colored tape to sections, or perhaps paint (or use a paint pen) to draw stripes around sections. This is what I am currently considering doing, but I'd love to hear your own ideas. Should I ensure that each photo has a minimum number of these targets in it's view? If so, what might be a reasonable minimum?
Thanks in advance for your help!
