PreF3R: Pose-Free Feed-Forward 3D Gaussian Splatting from Variable-length Image Sequence

We present PreF3R, Pose-Free Feed-forward 3D Reconstruction from an image sequence of variable length. Unlike previous approaches, PreF3R removes the need for camera calibration and reconstructs the 3D Gaussian field within a canonical coordinate frame directly from a sequence of unposed images, ena...
