Drones as Annotators: Amodal 3D Auto-Labeling for Ground LiDAR with Aerial Priors

Scaling perception data in autonomous driving is hindered by manual 3D bounding box annotation, a costly and labor intensive process requiring substantial domain expertise. Existing auto-labeling methods reduce this burden, but most of them rely on onboard sensors, where a single ground-level viewpoint yields occluded...
