Built-Heritage Multi-temporal Monitoring through Photogrammetry and 2D/3D Change Detection Algorithms

ABSTRACT

Cultural heritage assets are continuously exposed to risks and hazards. With the main aim to assess deterioration and improve conservation methods, the scientific community has proposed a variety of tools for the early identification of changes in heritage. Multidisciplinary approaches are common in heritage monitoring and conservation. This paper investigates the potential of change detection algorithms developed in remote sensing, and here applied at the monumental scale instead of the geo-spatial one. A monitoring methodology which integrates photogrammetry, 2D/3D change detection, and data interpretation is described and tested on the façade of the church of Stavros tou Missiricou (church of the Cross within the walls) in Nicosia, Cyprus.
