Comparative Analysis of Terrestrial Semi-automatic and Automatic Photogrammetry in 3D Modeling Process

Photogrammetry is a method of producing models of three-dimensional spatial structures based on two-dimensional photos, using a diverse range of software packages. It is currently being used for making and recording 3D models of structures and spatial entities of cultural architectural heritage. In this study, using a comparative method, the terrestrial semi-automatic digital photogrammetric method is analysed, as well as the terrestrial automatic method of photogrammetry. Both methods are presented in the case study of 3D models of the remains of the Nis Palace with an Octagon dating back to the Roman period and located on the town's fields.
