ABSTRACT
The documentation of historical objects and artifacts is still a very popular topic of many scientific articles. This proposed paper deals with the documentation and visualization of several small archaeological artifacts or findings. Two methods of documentation are used and compared for this purpose. One of them is spatial documentation with the short-range 3D triangulation scanner Konica – Minolta VI9. Using this technology, a precise 3D model of the artifact is obtained. On the other hand, the drawback of this method is the missing texture which is important for quality visualizations. Another approach deals with image-based modeling. This technology is based on a sequence of images of the object. In our laboratory we use the Agisoft PhotoScan or Photomodeler Scanner software. The final product of the processing is a high quality textured 3D model. This method can be considered as a non-expensive way of documenting large amounts historical objects or findings with quality results suitable for future visualization. But there are problems with very small and slender artifacts (small image overlapping area). One part of this article is focused on ways of visualization. The model can be exported to the 3D PDF format. Another way is using 3D viewers like Cortona and BS Contact. Nowadays, 3D printing has become very popular. We are able to produce a real print of the artifact.
