FreeSplat++: Generalizable 3D Gaussian Splatting for Efficient Indoor Scene Reconstruction
Contributions:
-
This work represents a pioneering effort in generalizable 3D Gaussian Splatting (3DGS) for large-scale reconstruction. To the best of our knowledge, it is the first framework to effectively apply generalizable 3DGS for indoor whole-scene reconstruction.
-
To address the challenge of feed-forward whole-scene reconstruction, we improve the fusion mechanism in FreeSplat [22] and propose an effective weighted floater removal strategy that can be seamlessly integrated into the framework to further remove the floaters.
-
We introduce a depth-regularized per-scene fine-tuning step after feed-forward 3DGS prediction. Leveraging the efficient and geometrically accurate initialization of 3DGS from our feed-forward pipeline, our whole-scene reconstruction framework provides a competitive alternative to vanilla 3DGS, achieving a significant improvement in reconstruction accuracy within considerably shorter training time.
