Sample bundle
Coherent rooms, cross-referenced, in the formats the field expects.
The sample bundle is the dataset in miniature. Coherent rooms with structured records, ScanNet-style instance aggregation, COCO 2D exports, egocentric walkthrough manifests, IMU sidecars, a full taxonomy with crosswalks, and a schema reference. Everything links back to a stable room_id.
Top-level files

Rooms in this bundle
| room_id | Properties | Notable for |
|---|---|---|
| rm_corner_king_1108 | Boutique corner king, high floor, stills + walkthrough + spatial capture | Reference room for general indoor perception evaluation |
| rm_petite_suite_905 | Petite suite with separated living and sleeping zones, soaking tub | Multi-zone layout reasoning, scene segmentation across functional zones |
| rm_ada_standard_212 | ADA mobility plus communication, roll-in shower, lever handles, audit annotations | Accessibility filtering and assistive-product evaluation |
Files per room
Each room ships as a fan of sibling files sharing the same room_id prefix. Modalities and labels are honest per record; if a capture or a label set does not exist for a room, its sibling is absent rather than null-filled.
| Suffix | Contents |
|---|---|
| .room.json | Structured room record (30+ fields: geometry, fixtures, ADA, amenities, capture metadata) |
| .scannet-style.json | ScanNet-style instance aggregation with ARKitScenes-format oriented 3D bboxes; references PLY mesh |
| .coco.json | COCO 1.0 export of 2D detection labels on stills (categories, images, annotations) |
| .video.json | Egocentric walkthrough manifest: intrinsics, extrinsics, fps, frame count, IMU sidecar reference |
| .imu.csv | Sample IMU CSV at 100 Hz with accel + gyro per axis and ms timestamps |
Structured room record
One JSON record per room. Schema is stable across versions; nulls are accompanied by an explicit reason code. Excerpt:

ScanNet-style instance aggregation
When a room is labeled, instance aggregation ships in a sibling JSON alongside a PLY mesh reference. Oriented 3D bboxes follow the ARKitScenes convention (centroid, axesLengths, normalizedAxes); units are cm and the world frame is right-handed, +Y up, origin at room center on the floor plane.
