Scal3R Uses Multi-Reference Pose Queries to Cut Drift in Online 3D Reconstruction

Chin-Yang Lin · hf · 2026-09-04

Chin-Yang Lin released Scal3R on Hugging Face, a scalable online 3D reconstruction method for long videos. It queries multi-reference relative poses with lightweight tokens and applies pose-graph optimization to reduce accumulated drift.

Notably, the approach improves long-video reconstruction without retraining the backbone network.
