A systematic approach towards reconstructing 3D curved models from multiple 2D views

Abstract

In this paper, we present a robust and systematic scheme that automatically interprets 3-view engineering drawings as central quadric surface mechanical parts. Initially a 3D wireframe, with no face information in it, is reconstructed from the three orthographic projections. Next, all candidate faces are found within the wire-frame, using a minimum-internal-angle searching method. Then, pseudo elements that could be generated from hack-projection are detected and deleted using a Decision-Chaining method. Finally, all true faces are assembled to form an oriented 3D object.
