3D Scanning and Visualization of Large Monuments of Timurid Architecture in Central Asia -- A Methodical Approach

The development of information technology (IT) now allows for rapid, semi-automatic digitization of cultural heritage objects, both typical museum exhibits and architectural monuments. However, the same IT development makes it possible to disseminate the results of digitization, i.e., to reach a wide audience. This article presents the methodology of 3D scanning and processing of the acquired data on the surface condition of large architectural objects to develop their models and make various variants of their visualization. The developed methodology was divided into many stages and steps. It provides methods, techniques, and recommendations on how to solve specific problems that interfere with the process of data acquisition under typical conditions of continuous access to the objects by tourists and the impossibility of turning the object off from the visitors. The methodology prepared was used and tested during field trips to Kazakhstan and Uzbekistan in 2018--2019 to prepare digital visualizations of objects belonging to the group of monuments called Timurid architecture. Preparation and in situ verification of 3D data acquisition procedures under different traditions, cultures, religions, customs, administrative procedures, time constraints, technical resources, and climatic conditions is of great importance for effectively equipping research expeditions dealing with the digitization of architecture in different areas of the world.
