Igel Column, Igel (Rhineland-Palatinate). Detailed 3D Documentation of a Famous Monument

Commissioned by:

  • LBB Trier

Project Content:

Terrestrial 3D laser scanning, high-resolution structured light scanning, photogrammetrical 3D documentation and CAD evaluation of the coloured copy of a Roman column monument.

Project Progress:

The Igel Column, 23 m high, is one of the best known Roman burial columns in Germany. A coloured reconstruction of this column is located at the Rhenish State Museum in Trier. The column is UNESCO World Heritage and was scanned by ArcTron 3D in 2012 using high-resolution 3D technologies. The original monument in Igel a.d. Mosel will be recorded in 2013. 

The burial column was built around 250 AD for the brothers Lucius Secundinius Aventinus and Lucius Secundinius Securus. It is decorated with relief showing everyday life scenes of drapers as well as mythological images. Aside from its fuction as a burial column, the monument might also have been an advertisement for the drapery trade of the Secundians in Roman Trier.

At first, single reliefs were recorded with highest precision by a structured light scanner. Afterwards, the whole monument was recorded. We deployed a combination of 3D laser scanning and 3D photogrammetry. Scans and detail images were taken from a lifting platform. A camera copter recorded additional material from the top of the column. 

All scanning data was processed by several engineers at our headquarters near Regensburg. Different software packages were deployed for processing and texturing the 3D model. Photorealistically textured high-resolution 3D models as well as orthophotos (monochrome and coloured) wer developed with our 3D information system aSPECT 3D. They are the basis for restoration work. 

The deployment of these combined scanning technologies allows a cost effective high-resolution documentation of such objects.
