On the 3D documentation of the Igel Column — Original and copy: Structured 3D survey and analytical 3D information system

A groundbreaking approach to preserving the Igel Column, a 23-meter Roman monument in Trier, Germany, and its early 20th-century replica, has been developed using advanced 3D documentation techniques. The study successfully integrated terrestrial laser scanning, structured light scanning, and SFM photogrammetry from both a lifting platform and a Micro Aerial Vehicle (MAV) to create photorealistic high-resolution 3D models of both structures. These models were managed in ArcTron3D's database-supported 3D information system, aSPECT3D, enabling systematic access to project data for restoration purposes. This method provides a comprehensive solution for documenting and analyzing decaying monuments, offering valuable insights for conservation efforts.
