Research questionHow can ground-to-satellite localization bridge severe viewpoint gaps without 3D lifting or depth models?Ground and satellite images of the same place differ radically in viewpoint, making correspondence difficult. Recovering 3D structure from one ground image is ill-posed, while BEV projections and external depth predictions can introduce distortion, latency, and computational cost.
