I would recommend you the pointcloud library. It's similar to OpenCv, just for point clouds. A generic filter approach is touse a downsampling (see voxelgrid) first. Maybe you can skip this for pico flexx witk 38k points... However, the next step may be the statistical outlier removal filter (see here). The SOR-filter is a bit expensive. You have to check whether it's worth or not...The contional outlier radius filter (link) was a bit faster in my case, but the result wasn't that satisfing as with the SOR.

So, that's already a bunch of filters.

Cheers Matthias

P.S.

Just in case you haven't so far: Make sure you won't put any forces to the usb connector on the pico flexx. We made a hughe effort to avoid any pulling on the cable but unfortunatly two cameras broke down
