Description
Structured3D is a large synthetic dataset of house designs with rich
ground-truth structured 3D geometry — lines, planes, rooms and their
relationships — created by professional designers (Zheng et al.,
"Structured3D: A Large Photo-realistic Dataset for Structured 3D Modeling",
ECCV 2020). In this project the room primitives are ingested into the IndoorGML
PostGIS schema (IP-040) via
notebooks/floorplans/converters/03_structured3d.ipynb, which turns the
primitive graph into room polygons.
Modality / size
- Modality: synthetic structured 3D scenes (primitive graph → room polygons); photo-realistic renders upstream.
- Source unit: millimetres (
source_unit="mm"), scaled to SRID 900010 (cm). - Scale: ~3,500 scenes / ~21k rooms upstream; a sample is converted here.
Role in this project
- The richest source for 2D + (toward) 3D indoor layouts: 2D room polygons load into PostGIS now; the upstream 3D primitives feed the LiDAR/mesh → ray tracer (Sionna / QuaDRiGa) path for true volumetric coverage.
- Loaded as one
Building+SpaceLayer(usage = structured3d); walls are shared edges between adjacent rooms plus the perimeter. Selectable in QGIS bybuilding_name/dataset.
Notes
- Upstream: github.com/bertjiazheng/Structured3D (research use — registration/licence upstream).
- Synthetic, so geometry is clean — useful as a control against the noisier real-home plans (zind, resplan).
- Datasets live outside the vault under
_attachments/floorplans/structured3d/(gitignored).
