TL;DR of the paper, generated automatically.

This is an arXiv paper introducing a LiDAR dataset for building facades, with functional labels.

  • Data: about 492 million LiDAR points from 26 buildings in Halifax, Canada.
  • Labels: semantic, instance, and per-instance functional attributes, which the authors call a first for facades.
  • Results: semantic segmentation is already hard. Instance separation and functional reasoning are harder.
