Robust Multi-Camera BEV Perception: An Image-Perceptive Approach to Counter Imprecise Camera Calibration

Recently, Bird’s Eye View (BEV) detection methodologies that utilize surround-view cameras have seen significant advancements in autonomous driving systems. Traditional methods, however, are constrained by their reliance on specific camera parameters, which poses challenges in generalizing across different vehicle-mounted cameras with varying poses and under adverse conditions. To address these challenges, we propose a robust BEV representation network that integrates Dual-Space Positional Encoding (DSPE) and image perception. This network is designed to enhance resilience to calibration errors and pose fluctuations, resulting in reliable detection performance on the Nuscenes dataset, even with imprecise extrinsic inputs. Our approach demonstrates competitive accuracy when compared to other methods that do not rely on temporal data, highlighting the effectiveness of our DSPE strategy in improving the robustness and accuracy of BEV detection in dynamic and challenging environments.
