Photogrammetry - Robust 3D imaging with algorithms

Presented at ToorCon San Diego 18 (2016), Oct. 16, 2016, 12:30 p.m. (20 minutes)

Once in a while, an object in the real world needs to be imported to the computer: scenery for gaming, engineering models, or archeological sites, for example. This is relatively easy if we’re trying to image a uniform grey cube. What if you want a full-color, very precise model of something on your table? How about something the size of a building? What about something the size of a grain of sand? Using photogrammety, your computer, and a few inherent rules, you too can digitize real world models like some sort of 3D wizard, as long as you can take pictures of the object. No special equipment necessary! We use freely available tools to perform this operation, and modern graphics cards greatly accelerate the output of this technique. If your neckbeard is prodigious enough, this method can even be parallelized using AWS machines. Join us for a comprehensive demonstration of digitizing objects in the real world with less eqiupment and know-how than ever!
