Surface Mesh Segmentation and Reconstruction with Smooth Boundary Curves

Abstract

In mesh segmentation for industrial design objects, each segment defined by a region with closed boundary should correspond to its underlying surface constructed according to the designer's intention. In order to generate those segments from the scanned data, we propose a method in which (i) more suitable regions are extracted by the region splitting/merging processing with a new splitting scheme from the obtained clusters, (ii) smooth and consistent boundaries are generated as intersection or contacting curves between the adjacent underlying surfaces, and (iii) the region is reconstructed with high-quality triangle facets. We demonstrate the effectiveness of our method by applying it to the scanned data of the real-world industrial design objects.
