BEVCon: Advancing Bird's Eye View Perception With Contrastive Learning

Ziyang Leng, Jiawei Yang, Zhicheng Ren, Bolei Zhou

RA-L 2025

We present BEVCon, a simple yet effective contrastive learning framework designed to improve Bird's Eye View (BEV) perception in autonomous driving. BEV perception offers a top-down-view representation of the surrounding environment, making it crucial for 3D object detection, segmentation, and traje

Occupancy Learning with Spatiotemporal Memory

Ziyang Leng, Jiawei Yang, Wenlong Yi, Bolei Zhou

ICCV 2025poster

3D occupancy becomes a promising perception representation for autonomous driving to model the surrounding environment at a fine-grained scale. However, it remains challenging to efficiently aggregate 3D occupancy over time across multiple input frames due to the high processing cost and the uncerta…
