The use of modern photogrammetric techniques in the inventory of historical monuments - focus on the Potocki Palace in Krzeszowice

Abstract

The study presents advanced measurement methods used in the inventory of historic buildings, focused on the Potocki Palace in Krzeszowice. The paper focuses on two main measurement methods that allowed comprehensive and accurate documentation to be obtained. The first technique was terrestrial laser scanning, using specialised laser scanners to collect data. In order to reproduce the actual colours and texture of the object under study, the scanning method was supported by photogrammetry. The second method was low-ceiling photogrammetry, which provided even more accurate data about the Palace. Data processing resulted in a three-dimensional (3D) solid, consisting of a multi-million-point cloud. This was followed by a vectorisation process, which made it possible to obtain a full-dimensional representation of the studied object. The results allowed a detailed analysis of the Potocki Palace, including the identification of damage and changes occurring over the years. This documentation provides a solid basis for future conservation, modernisation and research work related to the building. The paper also points out the potential possibilities of using modern technologies to visualize inventoried objects. The technique of Virtual Reality (VR) and showing the object in 3D, which has been popular so far, has recently found even wider possibilities giving input to the construction of so-called Augmented Reality (AR).
