requires line drawings for manufacturing, machining and production
of engineering equipments/objects.The generation of these
paper-based drawings or computerized drawings is a complex and time
consuming task. Conventionally, these drawings contain three two
dimensional (2D) orthographic views, namely top, front and side of
an object. Modern trends in engineering industry require three
dimensional (3D) engineering drawings. Therefore, to fulfill this
requirement the conversion of these 2D drawings to 3D drawings is
essential.This conversion is referred to as the reconstruction.
Various approaches have been proposed for the
conversion/reconstruction using existing drawings.
In this thesis, we developed 3D reconstruction methodology that uses
camera perspectives in the reconstruction process. Note that in the
existing approaches this feature (camera perspective) is not used.
Another salient feature of our approach is in its underlying
mechanism of tangential lines and hypothetical cuboid. Using our
proposed approach, manufacturing cost and time can be saved, and it
can also be helpful in technology transfer.
