Documentation of the Hall of Ancestors at Vranov nad Dyjí Chateau

Vranov nad Dyjí Chateau lies about 110 kilometres from Vienna on the southern border of the Czech Republic and is one of the most valuable buildings of the Central European baroque. It was created during the reconstruction of a royal castle that was first mentioned in 1100.

The chateau is in the western region of Podyjí National Park and is classified as a national cultural monument. The Hall of Ancestors is the largest hall of the chateau and is open to visitors.

The goal of documentation was to inspect the current state of paintings and test new methods of documentation that have been developed by the Dronument project.

This solution is intended to be used as a tool for historians and restorers working in large historical buildings to provide access to areas that are difficult to reach by humans. In these locations, it is impossible to have large scaffolding up for extended periods of time due to regular services, however such a setup is necessary for studying the long-term influence of restoration works. For example, some parts of the churches being inspected could not even be reached by workers for decades.

The system provides local 3-D position and attitude information without access to GNSS and is able to cope with bad lighting conditions with the use of a laser inertial sensory setup. This technology makes deployment possible indoors at great heights, as is characteristic of many historical monuments.
