Key Points

  • The paper introduces AirSplat, a training framework aimed at making 3D Vision Foundation Models more usable for pose-free, high-fidelity novel view synthesis (NVS) despite challenges in direct transfer.
  • AirSplat’s Self-Consistent Pose Alignment (SCPA) adds a training-time feedback loop to align supervision at the pixel level and reduce pose–geometry mismatches.
  • It also proposes Rating-based Opacity Matching (ROM), which uses a sparse-view NVS teacher’s local 3D consistency to filter out degraded 3D Gaussian primitives.
  • Experiments on large-scale benchmarks report significantly improved reconstruction quality over existing state-of-the-art pose-free NVS methods.
