Abstract
Abstract. The aim of this contribution is an analysis of related technologies for data capturing for creating a digital twin of selected construction. As a case project a baroque church was selected. Four technologies were used for object modelling: TLS (terrestrial laser scanning), digital close-range photogrammetry SfM (structure from motion) as a terrestrial and aerial (drone) technology, and PLS (personal mobile laser scanner). It was possible to combine data from drone and terrestrial photogrammetry, the model was compared to TLS and proved to be sufficiently accurate. The data from the PLS were more complex (inside and outside) but did not contain higher parts of the building. However, it suitably complemented the entire interior. The complex model can be made as joined model from all devices and it is suitable for export to virtual reality (VR).
