Abstract:
This thesis proposes a method of three-dimensional reconstruction of objects using a combi- nation of two di erent methods, Shape from Silhouette and Shape from Structured Light, focusing on reconstruction of archaeological vessels. Shape from Silhouette is a method suitable for reconstruction of objects with handles, whereas it is unable to reconstruct con- cavities on an object's surface, such as inside of a bowl. Shape from Structured Light can reconstruct such concavities, but it often creates incomplete models because of camera and light occlusions. The purpose of combining these two methods is to overcome the weak- nesses of one method through the strengths of the other, making it possible to construct complete models of arbitrarily shaped objects. The construction is based on multiple views of an object using a turntable in front of stationary cameras. The method is adaptive, because it automatically selects a subset of possible views, guided by the complexity of the object modeled. Results of the algorithm developed are presented for both synthetic and real objects.
