The application of Artificial Intelligence (AI) in Cultural Heritage surveying has gained notable interest, particularly in enhancing the classification and segmentation of 3D point clouds. Recent research focuses on automating processes to manage surveying data and integrating it into the BIM environment. The present research proposes a semi-automated AI-based pipeline to semantically classify architectural features in 3D point clouds and match them with an existing BIM library. The case study examines the school and theatre of the Crespi d’Adda industrial village, a UNESCO Cultural Heritage site. Data includes a 3D point cloud generated via terrestrial photogrammetry, with windows selected as the feature to model in the BIM library. The methodology encompasses three phases: (i) creating a Crespi d’Adda window dataset aligning with BIM library parameters; (ii) applying Machine Learning classifiers for semantic categorization; and (iii) using prediction algorithms to recognize windows in the point cloud, matching them to the BIM library, and calculating accuracy. This research bridges architectural representation and data mining, streamlining BIM reconstruction. Anticipated results include automated detection and labeling of elements with accurate placement in the BIM environment, enhancing efficiency and interdisciplinary integration.
AI for Archaeological Heritage Applications
Lo studio propone una metodologia basata sull’integrazione di algoritmi di intelligenza artificiale e algoritmi generativi per supportare la ricostruzione di manufatti archeologici frammentari. Attraverso tecniche di image generation (GAN, Transformer), semantic segmentation e modelli computazionali parametrici, il sistema consente di analizzare frammenti, riconoscerne l’appartenenza tipologica e generare ipotesi ricostruttive tridimensionali. L’approccio viene validato tramite un workflow iterativo che combina dataset visivi, classificazione geometrica e ottimizzazione tramite algoritmi genetici, con verifica finale da parte di esperti.
