Abstract |
We present a method for visual representation of
sculpture objects or the relief of surfaces. The equipment used
contains two digital cameras, a video projector and a laptop. The
video projector illuminates objects with a coded structured
pattern. A stereoscopic couple of images is registered by the two
digital cameras. The registration of the stereoscopic images is
aided by the coded illumination. A hierarchical block matching
technique is used for the estimation of an initial disparity
field, from which a dense disparity field is estimated. Based on
the disparities field the 3D surface of the object is
reconstructed. Using also views of the object the visual
representation is obtained. If more than one stereoscopic couples
are registered for an object, then using corresponding images the
3D models are registered for obtaining the whole 3D surface. The
methods and techniques developed have been applied successfully on reliefs from the Church Saint Titus at Gortys exposed at the
Historical Museum of Crete.
