New PARC-Loc framework enhances text-to-point-cloud localization accuracy

By PulseAugur Editorial · [1 sources] ·

Researchers have developed PARC-Loc, a new framework for text-to-point-cloud localization that improves accuracy by addressing issues like layout-inconsistent aliasing and boundary evidence incompleteness. The system uses Partial Assignment with Relational Consistency (PARC) to jointly model object compatibility and spatial relationships. This approach enhances submap selection at the coarse stage and expands context with relevant instances from adjacent submaps at the fine stage. Experiments on KITTI360Pose and CityLoc datasets demonstrated significant improvements, with PARC-Loc increasing Top-1 localization recall at 5m by 34% on KITTI360Pose. AI

IMPACT Improves accuracy in 3D map localization using textual descriptions, potentially aiding autonomous systems and robotics.

    PARC-Loc: Text-to-Point-Cloud Localization with Partial Assignment and Relational Consistency

    arXiv:2610.09761v1 Announce Type: cross Abstract: Text-to-point-cloud localization estimates a position in a city-scale 3D map from descriptions of surrounding objects. Existing coarse-to-fine methods retrieve submaps using aggregate learned compatibility and then localize within…
