During the renovation of Basilica of Esztergom, before scaffolding building, for the work of the restorers the damage detection of tambur and dome was needed. An accurate 3D damage map is the most suitable for this, which can be created from a laser based point cloud.
The lowest point of the tambur, where the laser scanner could be placed for the measurements, is on the height of 36 meters, compared to the ground floor.
Using a drone, a strong rope was transferred to the opposite side of the tambour of dome, and then with this, two wire ropes were bring back, so we built rail made from wire through the dome. We moved the scanner on the rail made from wire with the help of wrought iron product manufactured by us, so we were able to scan the dome from several positions.

The created point cloud is also a detailed 3D database about the current state of the dome, which measurable with millimeter accuracy. In this way, restorers can calculate exactly, how much plaster is missing, how much paint they will need during the work, and so on.
