Altitude-Adaptive Vision-Only Geo-Localization for UAVs in GPS-Denied Environments 事件

Altitude-Adaptive Vision-Only Geo-Localization for UAVs in GPS-Denied Environments arXiv:2602.23872v3 Announce Type: replace Abstract: To address the scale mismatch caused by large altitude variations in UAV visual place recognition, we propose a monocular vision-only altitude-adaptive geo-localization framework. The method first estimates relative altitude from a single downward-looking image by transforming the input into the frequency domain and formulating altitude estimation as a regressio
