SceneVerse: Scaling 3D Vision-Language Learning for Grounded Scene Understanding

   

We propose SceneVerse, the first million-scale 3D vision-language dataset with 68K 3D indoor scenes and 2.5M vision-language pairs. We demonstrate the scaling effect by (i) achieving state-of-the-art on all existing 3D visual grounding benchmarks and (ii) showcasing zero-shot transfer capabilities with our GPS (Grounded Pre-training for Scenes) model.
