MASt3R

Grounding image matching in 3D

Description

Two photos with very different viewpoints defeat classic feature matching, stalling 3D reconstruction. MASt3R from NAVER is an image matching model grounded in 3D.

It predicts dense 3D points and local features together, matching precisely under large viewpoint changes for reconstruction and localization.

Features



3D matching:Viewpoint-robust.

Dense:Precise correspondences.

Reconstruction:Multi-view.

Localization:Camera poses.
