As part of my master's thesis on the investigation of a wooden barrel construction in the Ensmad chapel, I worked together with the Surveying and Geoinformatics degree programme as part of an as-built survey. The aim was to carry out a 3D laser scan to document the structure in detail in the form of as-built plans. This provided the basis for mapping the damage.
A terrestrial 3D laser scanner on a LiDAR SLAM platform was used. This allowed the chapel to be recorded from the outside and inside.
The cramped conditions in the roof truss posed particular challenges. However, with a lot of imagination and unconventional methods, it was possible to create an overall point cloud.
The point cloud was subsequently cleaned up and could be further processed into plans using the PointCab software.
The collaboration with the surveying and geoinformatics degree programme was extremely valuable and demonstrated the importance of a comprehensive survey of the inventory. With the help of the deformation-orientated survey, it was also possible to record the full extent of the deformation caused by the damage.
My special thanks go to Mr Hepperle for his professional support and great commitment in the realisation of this project.
