Shape-Prior-Based Point Cloud Completion for Single-Stage Fully Sparse 3D Object Detection
Kaizheng Wang, Mingqian Ji, Jian Yang +1
Single-stage fully sparse 3D object detectors rely on point clouds data to detect objects in autonomous driving scenarios. However, the sparsity and incompleteness of point clouds…

Revisiting Token Compression for Accelerating ViT-based Sparse Multi-View 3D Object Detectors
Mingqian Ji, Shanshan Zhang, Jian Yang
Vision Transformer (ViT)-based sparse multi-view 3D object detectors have achieved remarkable accuracy but still suffer from high inference latency due to heavy token processing. T…

RayMamba: Ray-Aligned Serialization for Long-Range 3D Object Detection
Cheng Lu, Mingqian Ji, Shanshan Zhang +2
Long-range 3D object detection remains challenging because LiDAR observations become highly sparse and fragmented in the far field, making reliable context modeling difficult for e…
