Hi all,
where can I find information about FOSS-based georeferencing/processing of point clouds (like input coming from a NI device like a kinect or a xtion) - preferably done with GRASS ?

Hi Peter,
wrt GRASS:
r.in.xyz can read unlimited delimited ascii from stdin for a 2D slice
or 2.5D DEM. r3.in.xyz needs a disk file to work with (furthest developed
in grass7, still a few things to backport to grass6 addons).
how you get those inputs to ascii format is left as an exercise for
the student. 
but see also the PCL project, maybe some useful tool there:

the student will also look into Soeren's VTKGRASSBridge ("vtkImages can be directly written as GRASS raster maps into a GRASS location") and the NI/PointCloud-Plugin for Paraview
Thanks,

oh, and of course v.in.ascii in 3d mode without attribute
table or topology support can handle massive numbers of
points.
which tool to use all depends on what you want to do with
the data, and which data model you want to represent it.
we are blessed with many options, ready for any occasion.
