A Survey of Curved Surface Reconstruction Technique from 3-D Scattered Data

The technology on curved surface reconstruction from 3-D scattered data is the key technology of measure and geometric modeling systems for complicated curved surface. It includes unitary fitting and local fitting methods. The local fitting method is a common method of measure and geometric modeling systems for complicated curved surface because of its mathematical model the same as that of current CAD system. The technology, which links a measure system and geometric modeling system, will take on a wide prospect in practical application of engineering. At present, domestic and foreign experts have acquired plentiful and substantial achievements theoretically as well as practically.
