Dynamically tangible cultural heritage monitoring from web video sources

Climate change is serious problem, which can negatively affect the tangible cultural heritage. An actively solution to this problem is the long-term continuous monitoring of the cultural heritage, which is impossible in many cases. In this work we propose a methodology based on web video sources for generating high fidelity 3D meshes and estimating geometrically changes, which can indicate possible damaged areas. The ancient theatre of Epidaurus was selected for demonstrating the methodology and by using two YouTube video sources, high fidelity meshes were generated and compared by using free and open-source software. This work concludes on that tangible cultural heritage monitoring is possible by using web video sources.
