On the Consistency of Line-Drawings, Obtained by Projections of Piecewise Planar Objects

Heyden, Anders LU (1996) In Journal of Mathematical Imaging and Vision 6(4). p.393-412
Abstract
This paper deals with line-drawings, obtained from images of piecewise planar objects after edge detection. Such images are used, e.g., for navigation and recognition. In order to be a possible image of a three dimensional piecewise planar object, it has to obey some projective conditions. Criteria for a line-drawing to be correct is given in this paper, along with methods to find possible interpretations. In real life situations, due to digitization errors and noise, a line-drawing in general does not obey the geometric conditions imposed by the projective imaging process: Under various optimality conditions, algorithms are presented for the correction of such distorted line-drawings
