Abstract

Vision Language Models (VLMs) have achieved impressive performance in 2D image understanding; however, they still struggle with spatial understanding, which is fundamental to embodied AI. In this paper, we propose SpatialBot, a model designed to enhance spatial understanding by utilizing both RGB and depth images. To train VLMs for depth perception, we introduce the SpatialQA and SpatialQA$\boldsymbol{E}$datasets, which include multi-level depth-related questions spanning various scenarios and embodiment tasks. SpatialBench is also developed to comprehensively evaluate VLMs' spatial understanding capabilities across different levels. Extensive experiments on our spatial-understanding benchmark, general VLM benchmarks, and embodied AI tasks demonstrate the remarkable improvements offered by SpatialBot. The model, code, and datasets are available at https://github.com/BAAI-DCAI/SpatialBot.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
