Hi Bernd,
Well, could you give more info? E.g. what kind of scan:
laser/lidar/photo/other? This will influence your workflow.
+/-Open source laser/lidar could be based on lastools [1]
Open source photogrammetry could be based on AliceVision meshroom
[2,3], MeshLab [4] and blender [5]
In photogrammetry: Agisoft metashape [6] and pix4D [7] as good
commercial products.
BTW: 32 scans, if photos, is quite a very low number of photos for
reconstructing a 3D scene!
Hope this helps.
Cheers,
Benoit de Cabissole

Hi folks,
in a project on a former dumpside now to be transformed into a sand
lizard habitat, I saw the chance to get my hands dirty for the first
time on 3D scan data (terrestrial). I received 10GB of stuff, and now
I'm completely lost.
The data consists of .rwcx files, .tzf files and lots of other stuff.
Is there any chance that I can process any of this data with an open
source stack?
Or what should be done, to make them digestible?
Second step: There seem to be 32 different scans of the area form all
angles. In case I succeed to somehow load the data, how do I combine
them ?
For the first steps, I actually "only" would like to generate a decent
DEM from the data to be able to place some features on a map for the
guys in charge to do the habitat stuff.
Any kind of hints or links to reads about this topic would be appreciated
Cheers,
Bernd
