@charlesq34 hi,I want to prepare my own dataset for semantic segmentation, but I am confused about how to label the points in the point cloud. Do you have any good suggestions? best

Hi,

This is a goind point, and probably the most difficult step in all machine learning project : create training dataset.

Concretely you have to write PLY point clouds files associated to an "annotation file" containing a label id for each point (the easiest way should be the numpy format i think). Then merge your files in h5 format with prepare h5 scripts of this project.

The way to annotate each point with the good label id is up to you. Using any existing tool (CloudCompare, Blender...)
