Sat-NeRF: Learning Multi-View Satellite Photogrammetry With Transient Objects and Shadow Modeling Using RPC Cameras

no code implementations16 Mar 2022 Roger Marí, Gabriele Facciolo, Thibaud Ehret

We introduce the Satellite Neural Radiance Field (Sat-NeRF), a new end-to-end model for learning multi-view satellite photogrammetry in the wild.

Automatic Stockpile Volume Monitoring using Multi-view Stereo from SkySat Imagery

no code implementations1 Mar 2021 Roger Marí, Carlo de Franchis, Enric Meinhardt-Llopis, Gabriele Facciolo

The refined RPCs are then used to reconstruct multiple consistent Digital Surface Models (DSMs) from different stereo pairs at each date.

Robust Rational Polynomial Camera Modelling for SAR and Pushbroom Imaging

2 code implementations26 Feb 2021 Roland Akiki, Roger Marí, Carlo de Franchis, Jean-Michel Morel, Gabriele Facciolo

The Rational Polynomial Camera (RPC) model can be used to describe a variety of image acquisition systems in remote sensing, notably optical and Synthetic Aperture Radar (SAR) sensors.
