VI3: Grounding Pretrained 3D Foundation Models with Inertial Cues
VI3 is a model‑agnostic framework that grounds pretrained 3D foundation models (3DFMs) by using inertial measurement unit (IMU) data to provide metric scale. It initializes and preintegrates IMU readings to create a metric motion reference, which is then used to recover the scale of 3DFM outputs. The approach includes adaptable anchoring strategies for different 3DFM architectures and demonstrates scale recovery on synthetic and real aerial datasets without ground‑truth supervision.

GeoFF3D: Coordinate-Anchored Feed-Forward Reconstruction for Large-Scale UAV Mapping
GeoFF3D is a new feed‑forward 3D reconstruction method designed for large‑scale UAV mapping. It uses a coordinate‑anchored model that predicts camera poses and dense point maps directly in a gravity‑aligned Z‑up metric frame, while a spatial large‑scale reconstruction framework (SLRF) partitions images into overlapping chunks, propagates shared‑view priors, and aggregates local reconstructions hierarchically. Across nine aerial mapping blocks, GeoFF3D achieves the best average reconstruction quality, improving F@5 from 0.829 to 0.877, and can reconstruct 2,000 images in about five minutes.
