G1 continuity of B-spline surface patches in reverse engineering

Point-data processing and error analysis in reverse engineering

“…Go to step (2) and continue the search process for the next examined point. 4. If the examined point falls right on a mesh line (see point B in Fig.…”

The recovery of design intent in reverse engineering problems

“…A second approximation is needed to ensure that the different patches are continuous in position G 0 and in tangency G 1 on their shared edge, for which purpose it is necessary to deform the Bspline surfaces on the inside points, with minimum deformations of the area edges of each patch, by means of mathematical algorithms such as that used by Milroy, Bradley, Vickers, and Weir (1995). Weiyin and Kruth (1995) applies a fitting method based on least-squares B-spline curves and on surfaces, using a curve base and a surface base in each case.…”

Laser remanufacturing based on the integration of reverse engineering and laser cladding

“…In the process of part or product design, reverse engineering is an important method for constructing a CAD model from a physical part that already exists (Milroy et al, 1995;Fitzgibbon et al, 1997;Várady et al, 1997;Ma and Kruth, 1998). Most of the proposed solutions for reverse engineering are realised by two steps: digitising and surface modelling (Figure 1).…”
