Research Paper Overview
FishBEV: Distortion-Resilient Bird's Eye View Segmentation with Surround-View Fisheye Cameras
Summary
FishBEV is a novel BEV segmentation framework designed for fisheye cameras in autonomous driving. It introduces a Distortion-Resilient Multi-scale Extraction backbone for robust feature learning under distortion, an Uncertainty-aware Spatial Cross-Attention mechanism for reliable cross-view alignment, and a Distance-aware Temporal Self-Attention module to balance near and far field temporal coherence. Experiments on Synwoodscapes show FishBEV outperforms state-of-the-art baselines in surround-view fisheye BEV segmentation tasks.
