Capturing the Past: Photogrammetry for Safeguarding Sudanese Cultural Heritage Digitally

Abstract

Cultural heritage is a valuable asset for any country, and it is crucial to protect, restore, and preserve it because it is threatened by both nature and human actions. Preservation methods have always been a significant concern, and traditional methods of documentation, such as 2D drawings, pictures, and conventional 3D modelling systems, have proven to be inefficient in terms of cost, time, effort, and quality. However, with advancements in technology and digital transformation, more effective techniques have been developed. One such technique is photogrammetry, which has proven to be a convenient way to digitize cultural heritage. For countries such as Sudan, where rich inheritance is in inevitable danger of ongoing armed conflicts, it is important to preserve this cultural heritage. This paper studies the feasibility of using photogrammetry as a digitalization technique to preserve Sudan’s cultural heritage by reviewing previous experiences and conducting two case studies that investigate the applicability of the technique to non-experts, along with its potential and limitations. Selected objects were digitized using close-range photogrammetry with a low budget and simple equipment. The final outcome was promising, particularly for small and medium-sized objects. Finally, a list of recommendations is provided to facilitate the digitalization of Sudanese cultural heritage to preserve it.
