PAS3R: Pose-Adaptive Streaming 3D Reconstruction for Long Video Sequences
arXiv CS.CV

ArXi:2603.21436v1 Announce Type: new Online monocular 3D reconstruction enables dense scene recovery from streaming video but remains fundamentally limited by the stability-adaptation dilemma: the reconstruction model must rapidly incorporate novel viewpoints while preserving previously accumulated scene structure. Existing streaming approaches rely on uniform or attention-based update mechanisms that often fail to account for abrupt viewpoint transitions, leading to trajectory drift and geometric inconsistencies over long sequences.
