DeWorldSG: Depth-Aware 3D Semantic Scene Graph Generation via World-Model Priors

DeWorldSG generates spatio-temporally robust 3D semantic scene graphs from RGB-D sequences. It estimates instance-level geometric 3D Gaussian distributions through depth-guided filtering and represents each object as a probabilistic 3D node. It aggregates spatiotemporal evidence across object pairs and refines relations using contextual priors from a world model (V-JEPA 2). Improves triplet recall by 77.4% and predicate recall by 23.2% over prior SoTA.
