🌏🚶‍♂️🔍CV-Cities: Advancing Cross-View Geo-Localization in Global Cities

Description 📜

Cross-view geo-localization（CVGL） is beset with numerous difficulties and challenges, mainly due to the significant discrepancies in viewpoint, the intricacy of localization scenarios, and global localization needs. Given these challenges, we present a novel cross-view image geo-localization framework. The experimental results demonstrate that the proposed framework outperforms existing methods on multiple public datasets and self-built datasets. To improve the cross-view geo-localization performance of the framework on a global scale, we have built a novel global cross-view geo-localization dataset, CV-Cities. This dataset encompassing a diverse range of intricate scenarios. It serves as a challenging benchmark for cross-view geo-localization.

CV-Cities: Global Cross-view Geo-localization Dataset 💾

We collected 223,736 ground images and 223,736 satellite images with high-precision GPS coordinates of 16 typical cities in five continents. To download this dataset, you can click: 🤗CV-Cities or 🤗CV-Cities (mirror).
