Core Innovation
This paper introduces LiAuto-GeoX, a grounded driving transformer that integrates sparse LiDAR priors with a geometry-preserving distillation framework. It achieves compactness and real-time performance without sacrificing dense 3D reconstruction quality, addressing limitations of prior large-scale visual geometry models in surround-view consistency and geometric fidelity.
