The document discusses Project Scanner, which uses a camera, tripod, computer or laptop, and projector to take 3 photos of an object from different angles in order to scan and create a 3D model of the object. The photos are decoded by a program to generate data and export files in OBJ or DWG format. The files can then be opened in Rhino or 3D Max software to create a 3D terrain surface model of the scanned object.
