|The ancient city of Rome wasn’t built in a day and it took nearly a century to build St. Peter’s Basilica — but now the city can be digitized in just hours.
A new University of Washington computer algorithm uses hundreds of thousands of tourist photos to automatically reconstruct an entire city in about a day.
The tool is the most recent in a series developed to harness increasingly large digital photo collections available on photo-sharing Web sites. The digital Rome was built from 150,000 tourist photos that were downloaded from the popular photo-sharing Web site, Flickr.
Researchers led by Assistant Professor Sameer Agarwal said computers analyzed each image and in 21 hours combined them to create a 3-D digital model that allows a viewer to “fly” around Rome’s landmarks, from the Trevi Fountain to the Pantheon to the inside of the Sistine Chapel.
Earlier versions of the UW technology are known as Photo Tourism. That technology was licensed in 2006 to Microsoft, which now offers it as a free tool called Photosynth.
“With Photosynth and Photo Tourism, we basically reconstruct individual landmarks,” said study co-author Noah Snavely. “Here we’re trying to reconstruct entire cities.
The project that included Rick Szeliski of Microsoft Research, Professor Steve Seitz and graduate student Ian Simon is to be presented next month in Kyoto, Japan, during the International Conference on Computer Vision.

Meyers Spring Pictograph Site is located near the town of Dryden in West Texas between two ancient Comanche War Trails. The rock art is found on a limestone cliff face adjacent to Meyers Spring, one of the only stable sources of fresh water for many miles. The oldest art found at the site consists of the prehistoric Pecos River Style (2000 to 4000 years old). Most it has faded or has been covered by early historic (150 to 400 years old) pictographs that now dominate the site. The latest pictographs found are some the best preserved in North America and appear to chronicle the earliest contact between European and the native peoples of this area.
