BathyFacto: Refraction-Aware Two-Media Neural Radiance Fields for Bathymetry
arXiv CS.CV
•
ArXi:2605.10174v1 Announce Type: new Through-water photogrammetry based on UAV imagery enables shallow-water bathymetry, but refraction at the air-water interface violates the straight-ray assumption of Structure-from-Motion and causes systematic depth bias. We present BathyFacto, a refraction-aware two-media extension of Nerfacto integrated into Nerfstudio that targets metrically precise underwater point clouds.
