Augmented Reality in Tracking the Surface Geometry Change of Cultural Heritage Objects

Augmented reality is a field of presenting and visualizing the real-world problem enhanced by computer-generated algorithms. The computer-generated perceptual information becomes a premier research topic to solve various 3D problems. In this present age, it is very important to digitize the process of work and store it to keep track of the changes over time. This work is focused on storing digital documentation of the restoration of cultural heritage objects concerning the parameter of occurrences of surface geometry change on the surface of the objects. The paper shows the application of structured light techniques to the analysis of a cultural heritage object during restoration. In order to detect and visualize changes a global geometry analysis was applied and presented the outcome through a global distance histogram. The study also includes the discussion of facing possible challenges during the development of the algorithms for the change analysis.
