Crowdsourcing

Building Rome in a Day, new project out of the University of Washington Grail Lab uses 150,000 Flickr images tagged “Rome” to reconstruct the iconic city in 3D. Because tourist photos are taken from a multitude of vantage points, stitching them together into a cohesive 3D image creates rich and spatially accurate models.
The Rome project, which took 21 hours on a cluster of 496 computer cores, reconstructed some of the city’s most famous landmarks — the Colosseum, St. Peter’s Cathedral, Trevi Fountain and the Pantheon.
The team has also begun reconstructing other cities — Venice, which took 250,000 images and 65 hours, and Dubrovnik, at a more modest 57,845 photos and 22.5 hours.
The ongoing project has fascinating applications in reconstructing not only static landscapes, but also dynamic events as they unfold — in the era of citizen journalism, imagine using public images of anything from natural disasters (like the 2005 Indonesian tsunami) to political protests (like the recent unrest in Iran) to create an accurate record of history.
Amazing! isnt it?
