What VGGT Knows About Overlap: Probing Geometric Foundation Models for Co-Visibility

Filippo Ziliotto, Luciano Serafini, Lamberto Ballan, Tommaso Campari

A fundamental challenge in 3D reconstruction and robotic localization is co-visibility: determining which image pairs share overlapping visible surfaces, particularly in scenarios with minimal overlap. We demonstrate that VGGT implicitly encodes co-visibility as an emergent behav…Read more
