PC : Free software for visualization and processing of point cloud data

Synopsis

This session is dedicated to opensource softwares enabling to visualize and process point cloud data.

Pointcloud data can have various origins. We usually deal mainly with LIDAR data, but point clouds can also be generated from Structure from Motion algorithms. They can also come from very different systems like sensors or data collected from mobile devices.

This training presents some tools allowing to visualize data, as well as to apply frequent processing. The tools presented are mainly CloudCompare, MeshLab, as well as PDAL and PCL.

An opening towards online processing and visualization capabilities is given at the end of the session.

Goals

The course will give you the following skills :

  • Know the tools enabling to manage point cloud data
  • Know which tool is useful for which use
  • Know the bases for CloudCompare, MeshLab, PDAL and PCL
