3D Modeling and Digital Documentation of Heritage Architecture for Preservation and Restoration
Year: 2025
Type: article
Abstract: The preservation of heritage structures requires accurate documentation methods capable of capturing complex architectural geometries. This study presents a comprehensive digital workflow that integrates Terrestrial Laser Scanning (TLS) with CAD modeling to document and analyze the Baron Empain Palace in Cairo—an Indo-European landmark known for its intricate ornamentation. Traditional survey techniques often fall short in representing such complexity. To address this, high-resolution TLS data were acquired using the Z+F Imager 5006i, yielding over 159 million points, which were then processed through a structured pipeline involving noise filtering, mesh optimization, and CAD-based dimensional analysis. Using Geomagic Studio 12, the Mesh Doctor module repaired over 5 million mesh triangles, enabling the creation of a continuous polygonal model without compromising surface detail. A representative architectural column was selected to demonstrate the method’s effectiveness in preserving ornamental features. The workflow emphasized organic surface reconstruction over parametric modeling to maintain the structure’s historical authenticity. Key outputs included precise dimensional measurements, surface area, and volume calculations, which support applications such as material estimation, load distribution analysis, and restoration planning. The final digital model serves not only as a structural analysis tool but also as a long-term preservation asset. This research establishes a scalable, replicable workflow tailored to complex heritage sites, bridging technical precision with conservation needs. By advancing digital heritage documentation through accessible and high-fidelity modeling, the study contributes to sustainable cultural preservation and broader engagement through education and virtual access.
