Cultural Heritage 3D digitization means the capture of highly detailed representations of cultural artifacts and sites. By employing advanced aerial and terrestrial photogrammetry techniques, 3D digitization enables the preservation and documentation of heritage in digital format.
Preservation. Cultural artifacts and sites are often delicate and susceptible to deterioration over time. 3D digitization allows for their preservation in a digital form, safeguarding them from physical damage or loss. These digital replicas can serve as references for future generations and help conserve cultural heritage. Keep in mind that digitization does not preserve the real-life asset or it’s historical value, only digital information about it’s shape and color. 3D digitization does not substitute conservation practices.
Documentation. 3D digitization provides a comprehensive and accurate documentation method. It captures intricate details, textures, and dimensions of artifacts and sites that may not be possible with traditional 2D documentation. This detailed documentation is valuable for researchers, archaeologists, and historians, as it offers a precise record of cultural heritage. The wide range of deliverables that can be generated makes this method a main tool in any documentation process for Cultural Heritage, regardless of the type of the subject.
Access and Exploration. Digitized artifacts and sites can be accessed and explored remotely, transcending geographical barriers. Through interactive 3D viewers, individuals can examine cultural heritage from any location, gaining a deeper understanding of historical artifacts and sites. This accessibility broadens the reach of cultural heritage and promotes education and appreciation among a wider audience.
Research and Analysis. 3D digitization allows for in-depth analysis and research. Scholars and experts can examine artifacts and sites virtually, studying them from different angles, making measurements, and conducting virtual tests. This facilitates further research, promotes scientific analysis, and contributes to a more comprehensive understanding of cultural heritage.
Accuracy: Aerial and terrestrial photogrammetry techniques provide a high level of accuracy in capturing the geometry, dimensions, and surface details of artifacts and sites. By combining multiple overlapping images, photogrammetry creates a comprehensive and precise 3D representation of the surface.
Detail Preservation: Aerial photogrammetry captures large-scale environments, such as archaeological sites, with accurate spatial information (2-3 cm accuracy). Terrestrial photogrammetry focuses on smaller-scale objects, preserving fine details of artifacts (up to 0.01 mm accuracy). Together, they ensure that both macro and micro-level details are accurately captured.
Integration with Other Technologies: Photogrammetry can be combined with other technologies such as laser scanning or drone imaging to enhance the accuracy and level of detail in the captured data. This integration provides a more comprehensive dataset for analysis and visualization.
Cost-effective: Compared to other scanning technologies, aerial and terrestrial photogrammetry are often more cost-effective. They utilize standard cameras and equipment, making it accessible and affordable for cultural heritage projects with limited budgets.
