A comparative analysis between personal and terrestrial laser scanning for the documentation of heritage sites

Anotace: This paper presents a comparative analysis of mobile and terrestrial laser scanning techniques in the 3D surveying of Bashtova castle in Albania, showcasing the integration's efficacy in capturing a comprehensive and accurate representation of this historical structure. Personal laser scanning (PLS), characterized by its mobility and ability to capture data while in motion, offers advantages in terms of efficiency and coverage of large areas. Conversely, terrestrial laser scanning (TLS), with its stationary setup and high precision, excels in capturing detailed information and intricate architectural features. Thanks to the research on the case study of the Bastova Castle in the article, it can be stated that the integration of data from PLS and TLS is seamless with the help of modern software while respecting the basic photogrammetric-geodetic rules and demonstrates the possibility of creating a complex 3D model, usable for further analyses for architects and conservation professionals, as well as for restorers and civil engineers. Research has shown that the difference between point clouds from PLS and TLS is within one centimeter.
