New research tackles 3D scene reconstruction with satellite and ground imagery

By PulseAugur Editorial · [2 sources] ·

Two new research papers, submitted to arXiv in late August 2026, introduce advanced methods for 3D scene reconstruction using satellite and ground imagery. The first paper, "Ground-to-Satellite Localization in Unconstrained Image Collections for 3D Scene Reconstruction," proposes a hierarchical framework that leverages Structure-from-Motion models to align ground-level images with satellite views, enabling accurate metric scale estimation and geo-localization. The second paper, "GeoRay: Gauge-Aware Feed-Forward Satellite 3D Reconstruction in the Geodetic Frame," presents a feed-forward model that reconstructs dense surfaces in an absolute geodetic frame, addressing challenges like gauge ambiguity and non-central rational polynomial cameras. This method achieves high accuracy and completeness on the US3D benchmark. AI

IMPACT These advancements could significantly improve the accuracy and completeness of 3D scene reconstructions for applications like urban planning and geospatial analysis.
