Bootstrapping a 4D LiDAR Annotation Tool from Video Foundation Models

LiDAR-SAM2 is introduced, a framework that turns a 2D video foundation model, SAM2, into a scalable source of supervision for the 4D LiDAR domain and produces semantic and panoptic labels on SemanticKITTI that approach the quality of full human annotation from only a few points.
