On-the-fly Large-scale 3D Reconstruction from Multi-Camera Rigs
Recent advances in 3D Gaussian Splatting (3DGS) have enabled efficient free-viewpoint rendering and photorealistic scene reconstruction. While on-the-fly extensions of 3DGS have shown promise for real-time reconstruction from monocular RGB streams, they often fail to achieve complete 3D coverage due to the limited field of view (FOV).
Evidence notes
- RigScapes mounted two synchronized DJI Action 5 Pro cameras on a DJI Mavic 3 Pro to collect aerial multi-camera video at 1920 x 1080 and 2 fps.
- The aerial portion covers 1 square kilometre of scenes and supports evaluation of an on-the-fly multi-camera 3D Gaussian Splatting framework.
- On RigScapes, the proposed method reported 20.12 PSNR and 0.602 SSIM with a reconstruction time of 4 minutes 25 seconds.
