Researchers have introduced NoDrift3R, a novel framework designed to improve 3D reconstruction from long image sequences. This method addresses the significant degradation caused by cumulative camera pose estimation drift, a common issue in pose-free feed-forward 3D Gaussian Splatting. By coupling geometry and appearance through a Raymap-Guided Coupling Module, NoDrift3R optimizes RGB reconstruction, raymap consistency, and camera regularization simultaneously. The framework also incorporates a Dual-Frequency Viewpoint Scheduling strategy to enhance stability over wide temporal ranges, leading to improved rendering and pose estimation robustness. AI
