Tips for capturing branches, leaves, plants, vegetations, trees
How to get good results for capturing vegetation? Are there special tips and reconstruction settings to try?
I am testing scenes in nature with twigs, leaves, branches, and small details. I am using 500 to 1000 images, all registering correctly. The registration point cloud shows branches, leaves and small details, however after the reconstruction all the details are gone and only the large surfaces remain.

Hi,
There is no particular setting to use except you will probably want to use high detail. It looks from the sample pic that each leaf is only a few pixels wide. Then add to that the 2 x image downscale RC uses on normal detail and there isn't much leaf left to find features on.
You should also get a bit closer to the branches, imagine its a building and you are flying around it with a drone, you don't need to always have the whole thing in shot to get an alignment.
Also everything is shot from above, so there isn't much data from both sides of the leaves, there should definitely be some more loops at different heights.
The other thing is make sure to manually set your exposure especially if you have a bright light source on one side, any silhouetted pics will not be of much use.
I just scanned this in high detail. It's not great as i need to make many compromises on my settings due to lack of light:
Leaves are very tricky. Some scanning spray would also have helped a lot in my case. You need to get a lot of detail because they are so thin.
