OrthoTrack system estimates UAV trajectories using orthophotos

By PulseAugur Editorial · [1 sources] ·

Researchers have developed OrthoTrack, a novel system for estimating the continuous 6-DoF trajectory of unmanned aerial vehicles (UAVs) without relying on GPS or post-hoc alignment. This training-free method utilizes publicly available orthophotos and surface models as a prior map. OrthoTrack achieves real-time performance on a single GPU and significantly outperforms existing methods by anchoring keyframes to map data and propagating correspondences using optical flow. AI

IMPACT Enables more robust and accessible UAV navigation by reducing reliance on GPS and site-specific adaptation.

    OrthoTrack: Continuous 6-DoF UAV Trajectory Estimation Anchored in Public Orthophotos

    arXiv:2606.25245v1 Announce Type: new Abstract: Continuous 6-DoF pose estimation is essential for autonomous UAV operations. Yet, existing visual odometry and SLAM methods accumulate drift and yield only relative, up-to-scale trajectories. Single-frame geo-localization, in turn, …
