Anchor3R: Streaming 3D Reconstruction with Transient Anchors for Long-Horizon Visual Mapping

ArXi:2606.05035v1 Announce Type: new Long-horizon online visual mapping is a core capability for robot perception, requiring continuous camera-motion and scene-geometry estimation from visual streams under bounded memory and computation. Recent feed-forward 3D reconstruction models provide strong geometric priors, but their streaming variants often predict poses in a fixed coordinate system tied to the first frame or a persistent scene memory.
