Modeling of ancient period Sarcophagus with close-range photogrammetry

Abstract

Throughout history, Anatolia has been home to numerous societies with diverse customs.
Every civilization has left behind too many cultural artifacts from its era to count after
withdrawing from the historical arena. This heritage includes knowledge that dates back
hundreds or even thousands of years. To be passed on to other generations, this heritage
must be preserved. Technological ones have replaced traditional techniques of protection.
Registering the work is the first step in the conservation and documentation process. The
photogrammetric approach is one of the methods used today to recognize and capture the
3D model of the work without physically touching it. Actual texture can be applied to
images using the photogrammetric approach, and a 3D model of the piece can be created.
In this project, a 3D model of a Roman-era sarcophagus was created using
photogrammetric methods. The Samsung M31 mobile phone camera was used to take
pictures. By analyzing these data in Agisoft software, a 3D model of the sarcophagus was
created with a dense point cloud with 0.3 mm spacing and an average position accuracy
of 2.18 cm over the pairs of pictures. As a result of the study, using photogrammetric
techniques in conservation and documentation studies to protect historical and cultural
heritage and transfer it to the next generations has provided a significant advantage in
terms of accuracy, speed, and cost.
