Digital photography: The future of small-scale manufacturing?

What if it were possible to quickly and inexpensively manufacture a part simply by using a series of close-range digital images taken of the object? A method called photogrammetry has now been identified for its application in manufacturing. In this technique, digital images of an object that have been taken at various angles are used to create a point cloud -- or a large collection of points used to create 3D representation of existing structures -- from which a computer-aided design (CAD) file can be generated.
