Foundation4D recovers metric depth, extrinsics and ego-motion from multi-camera video
lealtaixe · x · 2026-10-29
A Foundation4D branch recovers metric depth, multi-camera extrinsics, and ego-motion from multi-camera video. Factorized attention combines views and time efficiently, and global pose optimization turns local predictions into coherent camera trajectories.
This is the camera calibration and self-motion estimation core of NVIDIA's Foundation4D framework.
