SuperMap: A Spatio-Temporal SLAM System for Visual-Language Navigation

SuperMap is a real-time 4D spatio-temporal mapping framework from CMU that integrates high-frequency geometric SLAM with asynchronous open-vocabulary perception. Its consistency-driven mapping engine maintains stable object identities and prunes outdated content under occlusions and scene changes, producing a queryable 4D scene-graph interface for VLM-based zero-shot reasoning and language-guided navigation.
