Using multiple satellite images from slightly off-vertical, they feed the messy combined image into a diffusion model to auto-complete its best guess, and use Gaussian splatting to find the best fit amongst multiple guesses - and the results are surprisingly good.
This effort is important because the alternative to obtain 3D views is flying aircraft at low altitude with multiple cameras and passes, which is expensive and can be impossible in restricted areas or conflict zones.
