The paper introduces MVLGeo, a unified framework for cross-view object geo-localization that combines multiple viewpoints into a single model. It employs Vision‑Language Reranking to use contextual text from the query view, a multi‑view Mixture‑of‑Experts architecture to share knowledge and reduce redundancy, and an adaptive elliptical prior for positional encoding. Experiments on CVOGL benchmarks show that MVLGeo achieves state‑of‑the‑art performance and robustness to input degradation.

S$^3$Geo introduces a structure‑semantic synergistic learning framework for cross‑view geo‑localization, combining a Decoupled Query Pooling module to capture local structural patterns, an optimal‑transport based contrastive learning scheme for soft cross‑view correspondences, and a Semantic Knowledge Distillation strategy from a frozen CLIP teacher to embed semantic priors. The method jointly models fine‑grained structural and semantic information, enabling robust matching between images from vastly different viewpoints such as drone and satellite views. Experiments on University‑1652 and SUES‑200 datasets show that S$^3$Geo outperforms state‑of‑the‑art approaches without increasing inference complexity.

UniGeo is a multimodal large language model designed for text-guided drone geo‑localization, enabling the identification of target regions in large image galleries from natural‑language descriptions. It integrates geo‑semantic understanding, cross‑view semantic generation, and candidate‑level verification within a shared vision‑language framework, establishing stable correspondences among local scene elements, spatial relations, and language. A multi‑stage training strategy progressively refines geo‑semantic learning, cross‑view mapping, and fine‑grained verification, yielding significant performance gains on GeoText‑1652, with R@10 and mAP improvements of 13.59 and 2.83 percentage points respectively.

The paper introduces a Spatial Context Modeling (SCM) module that traverses feature maps in four orthogonal directions to capture interactions among directional representations, thereby building richer scene layout representations for cross-view geo-localization. It also proposes a High-Frequency Information Guidance (HFIG) module that extracts stable structural cues from the frequency domain to emphasize edges and contours, improving robustness to appearance variations. Experiments show the method performs competitively on standard benchmarks and remains robust under challenging scenarios with unknown orientations and limited fields of view.

Global visual localization of unmanned aerial vehicles (UAVs) using remote-sensing reference maps has attracted increasing attention. However, acquisition-time and imaging-platform differences between UAV and reference imagery induce substantial cross-domain appearance and viewpoint shifts, challenging robust six-degree-of-freedom (6-DoF) pose estimation.
BEV3SR is a training‑free, backbone‑agnostic framework that converts RGB‑D video observations into a queryable metric bird’s‑eye‑view (BEV) scene memory, enabling evidence‑aware 3D spatial reasoning. It formalizes each query into a spatial task specifying reference frame, constraints, objective, and evidence type, then routes the query to either a deterministic Geometric Reasoner or a Visual Evidence Aligner. Across multiple 3D scene QA benchmarks, BEV3SR consistently improves performance on spatially intensive and open‑ended questions within a 16‑frame budget.
