About
BEVFormer is an official implementation of a camera-only framework designed for autonomous driving perception tasks. It leverages spatiotemporal transformers to learn unified Bird's-Eye-View (BEV) representations from multi-camera images. The framework effectively exploits both spatial and temporal information by interacting with these spaces through predefined grid-shaped BEV queries. A spatial cross-attention mechanism extracts features from regions of interest across camera views, while a temporal self-attention fuses historical BEV information recurrently. This approach has achieved state-of-the-art results in 3D object detection and semantic map segmentation, demonstrating performance comparable to LiDAR-based baselines.
