| Summary: | Computer tomography (CT) is an excellent technique for obtaining accurate 3D information about the human body. It allows to
visualize the organs, bones and blood vessels, furthermore it enables to diagnose anomalies and diseases. Its spatial reconstruction
capability supports other interesting applications, such as inspecting different, even valuable objects like ancient sculptures. Current
paper presents a methodology of evaluating CT and video imagery through the example of investigating a wood Madonna with infant
Jesus sculpture from the 14<sup><i>th</i></sup> century. The developed techniques extract the outer boundary of the statue, which has been triangulated to
derive the surface model. The interior of the sculpture has also been revealed: the iron bolts and rivets as well as the woodworm holes
can be mapped. By merging the interior and outer data (geometry and texture) interesting visualizations (perspective views, sections
etc.) have been created. |
