Computer Reconstruction of Quadric-Surfaced Objects from Two or More Visible-Line Projections.
Abstract
One of the key problems in the interaction between computers and the real world is scene analysis - the computer interpretation of photographic images of physical objects. This problem is also referred to as the reconstruction problem. This report deals with scenes composed of objects bounded by quadric surfaces. The visual information in the photographic image, extracted in the form of a matrix of quantized grey levels, is assumed to have been reduced to a line structure by an appropriate preprocessing routine. A procedure is outlined which, given two or more such line structures obtained from different vantage points, will yield a description of the three-dimensional scene, in spite of limited number of imperfections in the line structure data (e.g., missing, extraneous, or improperly joined line segments).
