Also known as: ZInD, Zillow Indoor Dataset

Description

The Zillow Indoor Dataset (ZInD) is a large public dataset of real, unfurnished homes annotated with floor plans, 360° panoramas, and 3D room layouts (Cruz et al., "Zillow Indoor Dataset: Annotated Floor Plans With 360° Panoramas and 3D Room Layouts", CVPR 2021). In this project the vector floor plans are ingested into the IndoorGML PostGIS schema (IP-040) via notebooks/floorplans/converters/02_zind.ipynb.

Modality / size

  • Modality: 2D vector floor plans (+ 360° panoramas and 3D layouts in the upstream release; only the vector plans are imported here).
  • Source unit: metres (source_unit="m"), scaled to SRID 900010 (cm).
  • Scale: ~1,500+ homes / ~70k+ panoramas upstream; a sample is converted here.

Role in this project

  • Source of varied real-residence layouts for 2D indoor experiments and for stress-testing room/wall derivation across many plans.
  • Loaded as one Building + SpaceLayer (usage = zind); walls are the shared edges between adjacent rooms plus the perimeter. Selectable in QGIS by building_name / dataset.
