Hi
I have a point cloud that I want to simplify. I need 1 point in every 1cmx1cmx1cm space/voxel.
I already did something similar, but that was in 2D with point clouds containing only ground points and with the resulting point cloud as some sort of DTM.
In short, I used the 2dgridaccumulator to make a grid. Then I calculated the mean Z value’s of al points in a grid tile and added that value to the centerpoint of that grid. Than I used the vertexcreator to make the new point cloud.
Now I need to do ‘kind of’ the same thing but in a 3D grid…
I was looking at some transformers: pointcloudduplicateremover, pointcloudsimplifier, pointcloudspatialthinner, 3dboundingboxreplacer…
I haven’t found a really good way to do this. Anyone with ideas?
