Multi-source 3D documentation improves monitoring and conservation of historical monuments, indicating a new paradigm for heritage preservation.

The aim is to evaluate the effectiveness of a multi-source workflow for documenting and diagnosing damage in historic buildings.
Used terrestrial laser scanning, UAV photogrammetry, and 3D camera scanning.
Employed coordinated acquisition and processing of data.
Conducted geometric consistency evaluations and distance measurements between data clouds.
Analyzed surface roughness, curvature, planarity, and linearity.
Implemented AI-assisted validation for degradation indicators.
Generated over 235 million points of data covering interior and exterior geometries.
Identified various types of damage, including cracks and plaster detachment.
Improved spatial completeness and anomaly detection using multiple sensors.
Established a reliable baseline for restoration interventions and long-term monitoring.

Oprea et al. (2026) studied this question.
