Glob3R: 3D Foundation Models Still Need Global Optimization
kwangmoo_yi · x · 2026-07-16
A paper by Deng, Li, Qiu, et al., titled 《Glob3R: Global Structure-from-Motion with 3D Foundation Models》. The core insight is:
- When using feed-forward geometry estimators for SfM, they should still be paired with global optimization and Bundle Adjustment (BA).
- The traditional SfM pipeline components—keyframes, view graphs, tracks, and BA—remain valuable under this new approach.
- The conclusion emphasizes that even if the model can directly predict geometric relationships, post-processing for global consistency optimization remains crucial.
