Abstract

In spite of the fact that 3D objects reconstruction from 2D views is an intensively researched problem, no comprehensive satisfactory solution has been found. This work contributes towards automating the 3D reconstruction by enabling automatic definition of features of planes in 2D orthographic projections. To this end, we introduce the concept of loops in 2D views and their states, which are topology/ line continuity attribute value combinations. Correspondence is established between a loop's state and its content attribute value, which may be matter, protrusion or depression. Ambiguous cases require interrogation of complementary views, as we demonstrate in a few examples. This work is designed to be incorporated as part of the Machine Drawing Understanding System, which is aimed at recognition and interpretation of engineering drawings.
