Scal3R from NVIDIA Accurate online 3D reconstruction on kilometer-scale sequences with only ~1% extra parameters on a frozen backbone, trained in 8 hours on a single GPU.

New at #ECCV2026: Scal3R. Why do online 3D reconstruction models collapse on long videos—even when their per-frame depth remains stable? We found that the local geometry is often still reliable; the global pose head is what breaks.
