This thesis explores the development and application of 3D technologies in the conservation and restoration of cultural heritage, tracing the evolution of photogrammetry from its early beginnings in the 19th century to modern digital innovations. The study begins with a review of the historical methods that shaped photogrammetry, including the pioneering works of Aimé Laussedat, who is often regarded as the "father of photogrammetry," and Albrecht Meydenbauer, who made significant contributions to the development of this discipline through the use of photography for precise measurement and documentation of architectural monuments. The thesis then focuses on the application of contemporary 3D technologies in conservation and restoration processes, with an emphasis on the digital documentation of historical coins and polychrome sculptures. By using software tools such as Polycam and Agisoft Metashape, precise digital models of these artifacts were created. These models not only allow for detailed analysis and preservation but also serve as the basis for the production of replicas through 3D printing and other advanced technologies. Digital models enable restorers to accurately reproduce damaged or lost parts, maintaining the original structure and appearance of the artifacts. In a comparative analysis, the thesis evaluates the performance of Polycam and Agisoft Metashape software in photogrammetric tasks. Polycam has proven to be an extremely useful tool for the initial approach to photogrammetry, especially for users with no prior experience. Its ease of use and fast data processing make it ideal for educational purposes, serving as a starting point for students or enthusiasts who do not have access to powerful computer hardware. On the other hand, Agisoft Metashape offers more advanced features and greater precision, making it more suitable for complex projects where a high level of detail and accuracy is required. The conclusion and discussion of the paper highlight the importance of integrating modern 3D technologies into the processes of cultural heritage preservation.
