Cultural heritage represents the overall cultural legacy of people and is one of the most important historical sources from which new generations learn about their ancestors and their way of life. For this reason, the preservation of cultural assets is of immense importance, and, like everything else, with the development of technology, methods of collecting and preserving cultural heritage documentation are being improved. The primary goal of documenting the condition of cultural heritage objects is to store a model of the object which serves as the basis for all further research. Additionally, it is essential to have a recorded state of the object prior to any potential natural disasters or accidents which could partially or completely destroy the object. Historically, the preservation and documentation of cultural heritage have relied on traditional surveying methods which can be time consuming, resource intensive and constrained by their limitations in capturing intricate details. However, laser scanning devices have evolved significantly over the years and the ability to integrate them into accessible and versatile mobile devices has opened up new opportunities for numerous scientific disciplines, as well as cultural heritage documentation and preservation. The goal of this paper is to compare the results of measurements obtained from terrestrial laser scanner—TLS and an integrated scanner consisting of mobile phone and RTK antenna. Apart from the results of the observations, other factors that may influence the applicability of the method are also considered, such as observation time, the cost of necessary equipment, data processing and user’s ability to operate the device.
