Using PDAL Wrench for Processing Point Clouds from the Command Line
Together with the QGIS Processing tools for processing point clouds, also PDAL wrench became available. This can be used to process point clouds using command line commands and makes it easier to automate procedures.
QGIS version: 3.32 Lima
PDAL Wrench: github.com/PDAL/wrench
Open data: AHN4 from geotiles.nl/

Hartelijk dank, goede uitleg!

Great video Hans !!!!. I woul like to know how can i calculate set operation between two point clouds, i mean (Union, Diference, Intersection ... etc). All this operations using command line

I don't think those point cloud tools exist for QGIS and PDAL wrench. Maybe Cloud Compare has some tools for that (www.cloudcompare.org/) or you can export the point clouds to vector format to do the analysis with vector data.
eXcellent video
Is pdal_wrench available as a docker container? I'm trying to get command line working on ubuntu but seem to have some dependency issues. a container would make it easy!

I'm not sure if there's one. You can post an issue at the Github page of pdal wrench: github.com/PDAL/wrench
Sir, would you mind to make a video on how to fit overlapping lidar data? 🤗
