Reasoning About Traversability: Language-Guided Off-Road 3D Trajectory Planning
A language refinement framework with geometry-aware preference optimization lets VLMs generate more traversable 3D trajectories for off-road vehicles, yielding modest gains in error, traversability compliance, and elevation consistency on the ORAD-3D benchmark.
