Laser Scanning Church Restoration Survey

Location: Church of San Paolo Pisa, Italy

Deliverables:

  • Point cloud in colour and grey modes
  • 2D AUTOCAD drawings, scale 1:50
  • REVIT 3D MODEL

Project description:

The Church of San Paolo survey in Pisa (925) was commissioned for the restoration project, the documentation, and monitoring of the static condition from the building.
The graphical representation of 2D sections and elevations at 1:50 scale made it possible to draw every single stone used and to identify crossing cracks system that compromises the church’s stability.

For this project, we used photogrammetry in recording the heritage of the church combined with Point Cloud data.

3D laser scanning technology can be used for different purposes such as:

  • highly accurate drawings for each detail, every line, and stone
  • used to identify crossing cracks system
  • to establish what compromise the church stability
  • a detailed restoration plan can be developed based on the survey

How we do it?

We use the latest laser scanning technology for restoration projects such as churches, which is no contact. It means that point cloud data together with 360-degree visuals is safely captured without any risk to the environment, historical objects, and buildings.
We use the most advanced software and different methods combining point cloud data and photography called photogrammetry. By processing a set of unoriented images acquired from multiple views, we deliver the most accurate 2D AUTOCAD drawings and 3D REVIT models.

Photogrammetry is applicable for different scales and can be used for historical buildings and landscapes to small objects.

Surveying historical buildings such as churches can be difficult and require understanding the appropriate level of detail, scale, and orientation. It also requires an understanding of historical architecture.

Our professional team can analyse when photogrammetry needs to be used and when another surveying method would be more suitable to achieve the result.
