Sat3R: Satellite DSM Reconstruction via RPC-Aware Depth Fine-tuning
arXiv CS.CV

ArXi:2605.07264v1 Announce Type: new Accurate Digital Surface Model (DSM) reconstruction from satellite imagery is critical for applications such as disaster response, urban planning, and large-scale geographic mapping. Existing approaches face a fundamental trade-off: optimization-based methods achieve strong accuracy but require hours of per-scene computation, while generalizable geometry foundation models offer near-instant inference but fail to generalize to satellite imagery due to the domain gap.
