Each from a slightly different angle and location on the ground. CV experts at UW had the idea to use these free photos as photogrammetry inputs and estimate a 3d model of notre dame. This requires very intense knowledge of CV because each tourist photo needs to be mapped to a physical location around the building and then used to create a 3d model. This is like a much more complicated version of epipolar reconstruction. I think it&#8217;s interesting how this could be applied to virtually any location with enough footage or images. I took a class in cv, but I don&#8217;t really understand how enough 2d information can construct a 3d model with lots of math. Now that notre dame has burned down, processes like this allow retroactive 3d models of a a location that can no longer be captured.<\/p>\n<p><img decoding=\"async\" loading=\"lazy\" class=\"alignnone size-medium wp-image-302\" src=\"https:\/\/courses.ideate.cmu.edu\/60-461\/f2022\/wp-content\/uploads\/2022\/09\/notre-dame-370x480.jpeg\" alt=\"\" width=\"370\" height=\"480\" srcset=\"https:\/\/courses.ideate.cmu.edu\/60-461\/f2022\/wp-content\/uploads\/2022\/09\/notre-dame-370x480.jpeg 370w, https:\/\/courses.ideate.cmu.edu\/60-461\/f2022\/wp-content\/uploads\/2022\/09\/notre-dame.jpeg 400w\" sizes=\"(max-width: 370px) 85vw, 370px\" \/><\/p>\n<p><img decoding=\"async\" loading=\"lazy\" class=\"alignnone size-full wp-image-303\" src=\"https:\/\/courses.ideate.cmu.edu\/60-461\/f2022\/wp-content\/uploads\/2022\/09\/notre-dame-pic.jpeg\" alt=\"\" width=\"400\" height=\"287\" \/><\/p>\n<p>https:\/\/www.washington.edu\/news\/2007\/11\/01\/vacation-photos-create-3d-models-of-world-landmarks\/<\/p>\n","protected":false},"excerpt":{"rendered":"<p>there are hundreds of thousands of tourist pictures of the notre dame.
