Neural 3D Reconstruction of Planetary Surfaces from Descent-Phase Wide-Angle Imagery

ArXi:2604.13235v1 Announce Type: new Digital elevation modeling of planetary surfaces is essential for studying past and ongoing geological processes. Wide-angle imagery acquired during spacecraft descent promises to offer a low-cost option for high-resolution terrain reconstruction. However, accurate 3D reconstruction from such imagery is challenging due to strong radial distortion and limited parallax from vertically descending, predominantly nadir-facing cameras.
