Tokyo 24/7: 16,000 Street View Images with Day-Night Query Pairs

16,000 reference images and 147 query images covering 49 locations across day, evening, and night cycles for visual geo-localization research. Developed by the SUTD Visual Computing Group and updated in 2020, it serves as an annotated subset of the Tokyo 24/7 Google Street View collection.

Use Cases

• Visual geo-localization using the 147 query images to identify matching locations in the 16,000-image reference set
• Cross-view image retrieval to test model performance across day, evening, and night lighting variations
• Benchmarking image descriptor performance using the 49 distinct query locations

Strengths

• Includes 147 query images across three distinct lighting conditions (day, evening, night)
• Contains 16,000 annotated reference images for retrieval tasks
• Released under the permissive MIT license

Limitations

• Small query set of only 49 unique locations
• Specific to the Tokyo geographic area, limiting global generalizability
• Column names and file formats are not explicitly documented in the metadata
