SceneGraphGrounder: Zero-Shot 3D Visual Grounding via Structured Scene Graph Matching
SceneGraphGrounder builds a persistent 3D scene graph from VLM-inferred relations in 2D views and solves grounding via constrained graph alignment, achieving competitive zero-shot results on ScanRefer with only RGB-D input.
