Dataset

TO-Scene contains 20,740 scenes with three different variants which are TO_Vanilla, TO_Crowd, TO_ScanNet.

1. Full TO-Scene data:

• You can download our dataset with the corresponding variants from Google Drive:

Format	TO_Vanilla	TO_Crowd	TO_ScanNet
ply (point cloud)	Download (4.3GB)	Download (2.1GB)	Download (4.3GB)
npz (xyz, color, semantic_label, instance_label, bbox)	Download (6.2GB)	Download (2.8GB)	Download (6.5GB)

• Alternatively, for mainland China users, we also provide Baiduyun link:

Format	TO_Vanilla	TO_Crowd	TO_ScanNet
ply (point cloud)	Download (4.3GB)	Download (2.1GB)	Download (4.3GB)
npz (xyz, color, semantic_label, instance_label, bbox)	Download (6.2GB)	Download (2.8GB)	Download (6.5GB)

• Additionally, you can download our TO-Real data we mentioned in the paper,

2. Meta data:

You may also need to download meta_data at Google Drive or Baiduyun, including train/val/test split in format of .txt and pre-calculated mean_size_arr (mean size of objects of different classes).

3. Build your own dataset:

We have released the original CAD placement file (json file, describing the position, scale, and orientation of the small objects). You can run your own rendering and reconstruction based on this original annotation file, with parameters (e.g. point density) in your control.

Benchmark on TO-Scene

We have provided the code implementations for running 3D semantic segmentation and 3D object detection on our dataset, with the corresponding instructions.

Note that TO-Scene dataset contains 60,174 tabletop object instances from 52 common classes. For reference, we show the classes of these small tabletop objects below, which can be downloaded here as well.
