Comprehensive design recovery for mechanical components

In the area of reverse engineering, much research is being done on capturing the form of an object for inspection and design recovery purposes. When using contemporary reverse engineering techniques to reconstruct an object, many three dimensional data points are collected along the object's surface. Surfaces are constructed from the point cloud data using best-fit polynomial methods. Because of errors (due to scanning and manufacturing techniques, wear, etc.), the point cloud data does not correspond to an ideal replica; therefore, design modifications may be necessary. In addition, the model is incomplete using existing methods unless computer tomography (CT) scans are utilized, which is cost prohibitive, as data collection systems do not readily capture information on recessed or internal features.
