Previous week

  • Looked for articles about roofprint / footprint differentiation but didn’t really find anything
  • Started looking at a few articles about roofprint / footprint from LiDAR

Discussion

  • LiDARHD of IGN is already classified but there is no separation of façades and roofs
  • BAG + BGT + AHN4 could maybe be used to train a model
  • CloudCompare is nice to visualise point clouds

Next week

  • Look for articles about point cloud classification, especially roof/façades, because façades are not classified by default and are a rare class (tail distribution)
  • Look at point cloud semantic segmentation methods:
    • KPConv
    • MinkowskiNet
    • PointTransformer
