creating mesh from 3D-scanned objects

[rgotama]

Hi there,

I just downloaded cloudcompare yesterday from a recommendation to do my project. I don't really have a lot of idea how to use the software, but I am learning through YouTube and this forum.
I have a 3D scanner and I am trying to scan mangrove trees/forests and print a portion of it with a 3D scanner.
Based on what I've learned, I opened my point-based data, estimated the normal (though I have no clue what this means) using the PCL wrapper plugin (didn't change the search radius), and did Poisson reconstruction.
The result is something I didn't expect? I think because I scanned on the outdoors, there was a lot of noise in the data, but I don't know how to reduce/eliminate that (yet).

I have attached some pictures. I did the Poisson reconstruction with octree depth (don't what this means either) of 5 and 10.

Hopefully it's not too much trouble to help a newbie out. Any recommendations, advice or even links to tutorials regarding this topic would be very much appreciated.

Best,
Rinaldi

Ah, mastering normals computation is definitely not trivial (especially if you don't now what it is ;). And it's even tougher with vegetation scans due to the leaves, etc.

Can you maybe send me a sample file so that I can see what can be done with your type of cloud/scene? (admin [at] cloudcompare .org)
