Researchers have developed a new method called Noise-Conditional Gated Rectification (NCGR) to improve 3D object detection in cameras by addressing inaccuracies in camera extrinsics. NCGR predicts and applies a 2D rectification offset to correct projection errors without needing to estimate full six-degree-of-freedom extrinsic corrections. This approach was evaluated on the nuScenes dataset with simulated perturbations, showing a significant performance increase compared to existing methods like BEVFormer and CAPE, while maintaining comparable performance under clean extrinsic conditions.
