An important research area in computer vision is developing
algorithms that can reconstruct the 3D surface of an object
represented by a single 2D line drawing. Previous work
on 3D reconstruction from single 2D line drawings focuses on
objects with planar faces. In this paper, we propose a novel
approach to the reconstruction of solid objects that have not
only planar but also curved faces. Our approach consists of
four steps: (1) identifying the curved faces and planar faces
in a line drawing, (2) transforming the line drawing into one
with straight edges only, (3) reconstructing the 3D wireframe
of the curved object from the transformed line drawing and
the original line drawing, and (4) generating the curved faces
with Bezier patches and triangular meshes. With a number
of experimental results, we demonstrate the ability of our approach
to perform curved object reconstruction successfully.
