tier4_pcl_extensions#

Purpose#

The tier4_pcl_extensions is a pcl extension library. The voxel grid filter in this package works with a different algorithm than the original one.

Inner-workings / Algorithms#

Original Algorithm [1]#

  1. create a 3D voxel grid over the input pointcloud data
  2. calculate centroid in each voxel
  3. all the points are approximated with their centroid

Extended Algorithm#

  1. create a 3D voxel grid over the input pointcloud data
  2. calculate centroid in each voxel
  3. all the points are approximated with the closest point to their centroid
