Sparse Annotation, Dense Supervision: Unleashing Self-Training Power for Occupancy Prediction With 2D Labels

RA-L 2026

Serving as a fundamental task in robotic navigation and autonomous driving, occupancy prediction is gaining increasing attention for its fine-grained perception of the 3D environment. Most existing methods rely on dense 3D annotations, which are expensive, labor-intensive, and difficult to scale in

OPUS: Occupancy Prediction Using a Sparse Set

NeurIPS 2024poster

Occupancy prediction, aiming at predicting the occupancy status within voxelized 3D environment, is quickly gaining momentum within the autonomous driving community. Mainstream occupancy prediction works first discretize the 3D environment into voxels, then perform classification on such dense grids…

Towards Stable 3D Object Detection

ECCV 2024poster

"In autonomous driving, the temporal stability of 3D object detection greatly impacts the driving safety. However, the detection stability cannot be accessed by existing metrics such as mAP and MOTA, and consequently is less explored by the community. To bridge this gap, this work proposes (), a new…

Curricular Object Manipulation in LiDAR-Based Object Detection

CVPR 2023poster

This paper explores the potential of curriculum learning in LiDAR-based 3D object detection by proposing a curricular object manipulation (COM) framework. The framework embeds the curricular training strategy into both the loss design and the augmentation process. For the loss design, we propose the…
