CalibAnyView: Beyond Single-View Camera Calibration in the Wild

Boying Li, Cheng Zhang, Daniel Cremers, Hamid Rezatofighi, Ian Reid, Weirong Chen

CalibAnyView enables camera calibration from any number of views in the wild by enforcing cross-view geometric consistency.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

CalibAnyView consistently outperforms state-of-the-art methods, achieves strong robustness under single-view settings, and further improves with multi-view inference.

C2weakest assumption

The constructed large-scale multi-view video dataset sufficiently covers the diversity of real-world camera models, dynamic scenes, motion trajectories, and lens distortions so that the learned model generalizes beyond the training distribution.

C3one line summary

A multi-view transformer predicts dense perspective fields that feed a geometric optimizer to estimate camera intrinsics and gravity from arbitrary numbers of real-world views.
