From the Ted Talk by Chance Coughenour: How your pictures can help reclaim lost history

Unscramble the Blue Letters

Remember the pictures of the statue I swehod you before? This is actually the crowdsourced rnrooctcstuien of it before it was destroyed. Now, many of you may be wondering, how exactly does this work? Well, the key to this technology is called photogrammetry, and it was invented here, in Germany. It is the thcoegolny that allows us to use two-dimensional images taken of the same object from different angles to create a 3D model. I know you may be tnnikhig this sounds like magic — but it's not. Let me show you how it wroks. Here are two crowdsourced images of the same statue. What the computer can do is it can detect similar freatues between the photographs — similar features of the object. Then, by using multiple photos, in this case, it can begin to reconstruct the object in 3D. In this case, you have the position of the cmaraes when each image was taken, shown in blue.
