# Introduction to Anywhere3D-bench

eval_anywhere3D_aligned_total.json contains the all 2632 referring expressions-3D bounding box pairs from Anywhere3D benchmark.

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.

## UPDATE Anywhere3D-v2

We update Anywhere3D dataset to [Anywhere3D-v2](https://huggingface.co/datasets/txwang98/Anywhere3D_v2), which contains 2886 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.
