IMPACT OF THE METHOD OF REGISTERING TERRESTRIAL LASER SCANNING DATA ON THE QUALITY OF DOCUMENTING CULTURAL HERITAGE STRUCTURES

摘要

When documenting historical structures and objects, especially delicate artefacts such as pieces of sacred art, only techniques that allow remote, non-contact methods that enable the most precise measurements should be used to obtain data. TLS can be considered as such a technique however in order to obtain complete information for the entire structure, there is usually a need to acquire data from more than one measuring station. In this case, the most important and essential step of processing TLS data is the registration of scans. The paper contains a description of research and analyses concerning the registration of point clouds using three methods: manual, automatic and a combination of the two. The research was carried on measurement data from a historical synagogue. The structure was divided into three parts - three scans. The accuracy with which these scans were registered was assessed and a 3D model of the interior was created.
