TC-VIML

Tightly-coupled Visual/Inertial/Map integration with observability analysis for reliable localization of intelligent vehicles.

TC-VIML proposes a tightly-coupled visual-inertial odometry (VIO) system that leverages a 3D prior line map for drift-free localization. Unlike loosely-coupled methods, our approach deeply integrates line features into a factor graph optimization framework, supported by a robust cross-modality matching and outlier rejection strategy.
