Face Identification from the Line Drawing with Hidden-Parts-Drawn of a Planar Solid
Shi Yi-kai · Journal of Engineering Graphics · 2009
Face identification is a key step to the 3D reconstruction from a single 2D line drawing.Some of elementary theorems and interrelated deductions are proposed to make certain real faces as searching cycles and help to automatically delete a set of cycles that are not real faces.A recursion-based algorithm for searching for all of cycles and identifying faces from the cycles is given from a line drawing with hidden-parts-drawn.This method is applied to objects with planar faces.The experimental results show that the algorithm is reliable.
