Pinpoint system grounds image geolocation using cross-source retrieval

Researchers have developed Pinpoint, a new system for determining the geographic location of images. Pinpoint uses a retrieve-and-rerank approach that combines both user-uploaded internet photos and street-view imagery. This method learns a shared embedding space to retrieve candidate locations and then refines these predictions using visual and GPS features, outperforming previous state-of-the-art results on standard benchmarks.
