Virtual measurement of complicated surface in reverse engineering
Published January 01, 2001 by Institution of Mechanical Engineers in United Kingdom
Quality of composite triangular Bézier patch reconstructed from measuring points is usually not good enough to apply in engineering. A virtual measuring method is proposed to solve this problem. First surface region with bad quality is extracted and vertices of the surface region are approximated with B-spline surface. Then the B- spline surface is used as a new local virtual model to finish re-sampling and meshing. At last the local triangular meshes are merged with the initial one. As a conclusion, example is shown to demonstrate feasibility of the algorithm for improving the local surface's quality.
