Partially Matching Submap Helps: Uncertainty Modeling and Propagation for Text to Point Cloud Localization

ICCV 2025poster

Text to point cloud cross-modal localization is a crucial vision-language task for future human-robot collaboration. Existing coarse-to-fine frameworks assume that each query text precisely corresponds to the center area of a submap, limiting their applicability in real-world scenarios. This work re…

Semantic Ambiguity Modeling and Propagation for Fine-Grained Visual Cross View Geo-Localization

AAAI 2025technical

Visual cross view geo-localization is generally approached within a joint retrieval-and-calibration framework. However, existing methods overlook semantic ambiguities arising from query and reference images characterized by low overlap, dynamic foregrounds, viewpoint changes, and perceptual aliasing…
