Researchers have developed RECO, a novel framework designed to improve 3D object detection in intelligent transportation systems by compensating for extrinsic perturbations. This method addresses the sensitivity of existing systems to slight deviations in camera extrinsics, which can lead to feature misalignment and reduced localization accuracy. RECO employs piecewise 6-DoF pose offsets, partitioning the scene into near and far regions to estimate specific corrections and using a differentiable gate to blend these compensated geometries for stable optimization. The framework also incorporates an auxiliary reprojection loss to refine extrinsics by comparing projected 2D bounding boxes with 2D annotations, demonstrating consistent improvements on benchmarks like DAIR-V2X-I and Rope3D.
