SatSplatDiff: Geometry-preserving generative refinement for high-fidelity satellite Gaussian Splatting
SatSplatDiff is a unified pipeline for satellite 3D reconstruction that improves Gaussian Splatting by using shadow casting to guide generative refinement. It combines photogrammetric initialization, geometric optimization like multi-scale refinement, and diffusion models conditioned on shadows. This method achieves state-of-the-art accuracy and visual fidelity while preserving scene geometry.
