Summary:

The goal of 3D scanning is the inverse of computer aided manufacturing: given a physical object, such as a clay model of a car, a turbine blade, a chair, or a house, create an electronic representation of the object, capturing its shape, color, reflectance, and other visual properties.

3D scanning is similar in principle to a number of other important technologies (like photocopying and video) that quickly, accurately, and cheaply record useful aspects of physical reality. These technologies have had an enormous impact, primarily because electronic representations can be used in ways the original physical objects cannot. For example, they can be stored in, searched for, and retrieved from databases, transmitted electronically over long distances, viewed on CRTs, used in computer simulations, manipulated and edited in software, and used as templates for making electronic or physical copies.

3D scanning is roughly in the same state as photocopying before the invention of xerography, or home movies before the invention of compact video cameras. By analogy, it is reasonable to expect that the development of the technology will open up many new applications, in areas such as: reverse engineering; industrial design; repair, reproduction, and improvement of machinery; medical diagnostics, analysis and simulation; 3D photography; and building rich virtual environments.

Development of 3D scanning requires contributions from electrical and mechanical engineering (sensor development), computer science (geometric modeling), statistics (stochastic aspects of shape estimation) and mathematics (analysis of estimation functionals, geometry, topology).
