Introduction to Anywhere3D-Bench(anywhere3d_v2)
anywhere3d_v2.json contains the all 2886 referring expressions-3D bounding box pairs from Anywhere3D benchmark. It's based on the first version of Anywhere3D dataset, which contains 2632 referring expressions-3D bounding box pairs. We increased the number of annotations for the two most challenging grounding levels in Anywhere3D-Bench: the space level and the part level. Specifically, 106 annotations were added to the space level and 148 to the part level, with a particular focus on expanding the most difficult movement tasks within the part level.
The meaning of each key in the dictionary is as follows. The first table contains the fields that directly related to expressions-3D bounding box pairs while the second table contains fields that are helpful for annotation interface.
| Field Name | Description |
|---|---|
| grounding_level | Grounding level of the expression, selected from one of the four values: ["area_level", "space_level", "object_level", "part_level"]. |
| expression_type | Specifies the type of expression at each grounding level. |
| datasetname | Selected from one of the four values: ["scannet", "multiscan", "3RScan", "arkitscene_valid"]. |
| scene_id | From simplicity during Human Annotation and Verification, we rename the scene_id in the original dataset. |
