Dual SAM3 + Seam Mask: A 4K Panoramic 3DGS Reconstruction Workflow
janusch_patas · x · 2026-08-05
The author shared the results of reprocessing old OSMO360 panoramic data using a new workflow (combining Dual SAM3 and a seam mask), achieving a 4K visual output.
The pipeline includes:
- Capturing a 10-minute walking footage with OSMO 360 (with 'RockSteady' disabled).
- Extracting frames and applying masks in a custom 3DGS tool, yielding 613 images.
- Running Structure from Motion (SfM) in Metashape Standard using the generated masks.
- Performing cubemap conversion and parallax reduction.
- Training the 3D Gaussian Splatting (3DGS) and setting up camera work using LFS.
The author notes that the sparse point cloud generated from this updated workflow looks significantly better than previous iterations.
