AN APPROACH TO 3D DIGITAL MODELING OF SURFACES WITH POOR TEXTURE BY RANGE IMAGING TECHNIQUES. ‘SHAPE FROM STEREO’ VS. ‘SHAPE FROM SILHOUETTE’ IN DIGITIZING JORGE OTEIZA’S SCULPTURES
Despite eminent development of digital range imaging techniques, difficulties persist in the virtualization of objects with poor radiometric information, in other words, objects consisting of homogeneous colours (totally white, black, etc.), repetitive patterns, translucence, or materials with specu...

| Summary: | Despite eminent development of digital range imaging techniques, difficulties persist in the virtualization of objects with poor
radiometric information, in other words, objects consisting of homogeneous colours (totally white, black, etc.), repetitive patterns,
translucence, or materials with specular reflection. This is the case for much of the Jorge Oteiza’s works, particularly in the sculpture
collection of the Museo Fundación Jorge Oteiza (Navarra, Spain).
The present study intend to analyse and asses the performance of two digital 3D-modeling methods based on imaging techniques,
facing cultural heritage in singular cases, determined by radiometric characteristics as mentioned: Shape from Silhouette and Shape
from Stereo. On the other hand, the text proposes the definition of a documentation workflow and presents the results of its
application in the collection of sculptures created by Oteiza. |
