GeoState: Learning View-Decoupled Geometry States for 3D World Modeling
Novel architecture for 3D scene understanding with improved predictive capabilities for autonomous systems and robotics.
AI Summary
GeoState introduces a view-decoupled geometry representation for 3D world modeling that separates scene dynamics from camera motion, outperforming prior models on Waymo and generalizing to KITTI/nuScenes.
Excerpt
Recent 3D world models increasingly use features from geometry foundation models (GFMs) as predictive world states, benefiting from their rich geometric priors. However, the view dependence of these features entangles scene dynamics with camera-induced variation, making the resulting state evolution harder to predict. We propose GeoState, a view-decoupled geometry representation for predictive 3D world modeling that separates scene-state evolution from camera-dependent observation. Specifically,
