D2S: Towards Efficient Sparse 3D Object Detection via Dense to Sparse Knowledge Distillation
ICASSP 2025accepted
LiDAR-based 3D object detection is widely used in high-level autonomous driving schemes. However, the cumbersome modules in most 3D detectors lead to substantial computational overhead. Despite knowledge distillation (KD) is an effective approach for compressing models, previous methods cannot be ex…
