Multiresolution surface blending for detail reconstruction

Abstract

While performing mechanical reverse engineering, 3D reconstruction processes often encounter difficulties capturing small, highly localized surface information. This can be the case if a physical part is 3D scanned for life-cycle management or robust design purposes, with interest in corroded areas or scratched coatings. The limitation partly is due to insufficient automated frameworks for handling – localized – surface information during the reverse engineering pipeline. We have developed a tool for blending surface patches with arbitrary irregularities, into a base body that can resemble a CAD design. The resulting routine preserves the shape of the transferred features and relies on the user only to set some positional references and parameter adjustments for partitioning the surface features.
