Prior-Infused 3D Gaussian Splatting for Robust Sparse-View Reconstruction
Sparse-view 3D Gaussian Splatting (3DGS) is prone to severe geometric failures and appearance inconsistency due to optimization ambiguity. We introduce Prior-Infused 3DGS (PI-3DGS), a COLMAP-free framework that systematically integrates robust multi-view geometric priors into the 3DGS pipeline. Our framework consists o...
