MLLMs show promise for zero-shot geo-localization with language reasoning

Researchers have explored using multimodal large language models (MLLMs) for zero-shot language reasoning in cross-view geo-localization. The study found that while MLLMs can generate descriptive text for ground-level images and satellite tiles, these descriptions alone are not discriminative enough for accurate localization without training. However, when the search pool is narrowed, MLLM-generated descriptions can improve localization accuracy and provide interpretable evidence for matches, though they struggle with fine appearance details compared to trained visual retrievers.
