Abstract

The proposed contribution illustrates the case study of a close-range aerial photogrammetric survey on portions of the roofs of the University of Pavia historic complex. The research activities were carried out for semi-automatic generation of systems for recognition and monitoring of technological elements. The procedure involved the semi-automatic segmentation of the mesh using feature-region extraction algorithms, starting from SfM mesh models optimised in polygonal edge detail. The pipeline was evaluated from the architectural scale (recognition of chimney pots or skylights) to the scale of technological details (recognition of the roof tiles).
