The Politecnico di Milano takes part in the restoration of the floor of the Church of the Holy Sepulchre in Jerusalem. The Politecnico di Milano has created the guidelines for modelling and sharing data for the conservation and restoration project and has performed a detailed survey to document the state of conservation prior to the intervention.

The researchers created models of the floor and the surrounding architecture, starting from the laser scanner data. The high-resolution photogrammetric survey, carried out on site by researchers from the Politecnico, acquired over 50,000 high-resolution images, using a system designed ad hoc.

The researchers created models of the floor and the surrounding architecture, starting from the laser scanner data. This laser scanner data was acquired by the project coordination group on-site, in the midst of the pandemic (led by architect Osama Hamdan).

“The system we designed consists of a special trolley on which we engineered an articulated lighting and acquisition system, with controlled intensity and coloring.

This was integrated with a topographic survey for processing and verifying the final result, a digital image, an orthophoto, with very high resolution, metrically reliable and precise, of the entire floor of the Church of the Holy Sepulchre,” said Prof. Luigi Fregonese from the Department of Architecture, Construction Engineering and Built Environment at the Politecnico di Milano.
