| Abstract | | Creating digital replicas of unique biological findings or archeological artifacts has become a desirable
task, which enables to spare original integrity and enhance accessibility of valuable objects to a wide range of experts
as well as public. In recent years, specialized scanning devices have been challenged by performance of photogrammetry
software tools capable of processing unstructured image sets and providing three-dimensional digital models in return.
Simplicity, portability and affordability predetermine photogrammetry to be the method of choice if three-dimensional
documentation is to be conducted at remote facilities and outdoor locations.
The present paper tests technical limitations of two 3D documentation techniques – close range photogrammetry carried
out in Agisoft PhotoScan software and laser scanning conducted with MicroScribe/MicroScan scanning unit while
documenting pelvic bones and sacra from the Upper Paleolithic triple burial of Dolní Věstonice, Czech Republic. For
photogrammetry, two different approaches to generate closed textured 3D models were confronted – alignment of partial
polygonal meshes and joint processing of multiple image sets.
Our results showed that photogrammetry provided high-resolution 3D models appended by photorealistic texture. In
terms of depicted details, the photogrammetry-generated models were comparable to those of laser scanning. However,
the robust performance of the employed algorithm was achieved at the expense of extensive time and labor demands,
which for many experts may be difficult to justify. In conclusion, photogrammetry should be considered a suitable
substitute for surface scanners only if conducted for occasional and/or out-of-lab documentation tasks. | | | | Keywords | | Photogrammetry ‒ Laser scanning ‒ Three-dimensional documentation ‒ Skeletal remains ‒
