Fitting 3D known data into sculptured surfaces has received extensive attention. However, most algorithms available are suitable only for an isolated surface. A part typically contains multiple surface regions that must be blended to a degree of continuity. The conventional approach based on blending, lofting, stitching, etc. cannot guarantee the quality of the surface near the jointed area. The purpose...
It is generally necessary in 3D scanning to divide a wrap-around object into several regions, each of which is measured individually. A series of pre-processing procedures must be implemented to prepare the data for use for surface reconstruction. Registration is a procedure for unifying the coordinate systems for multiple sets of scan data. Three registration algorithms, 3 points to 3 points, 3 spheres...
