Özet:

Modeling objects with different size and geometry and extracting metric information of this object is more difficult than ordered geometric structures. Especially, analyses and measurements to be made on similar structures cannot be accurate and precise with conventional methods such as minarets, domes, columns, mausoleums, and statues that have a conical, spherical, or cylindrical shape. Three-dimensional (3D) scanning technologies such as Terrestrial Laser Scanners (TLS) are important tool for modeling to complex structures Clearly, 3D scanners are more suitable than conventional methods for measuring objects with disordered and complex surfaces. It is one of the best methods for applications with similar complex structures. However, the biggest disadvantage of ground-based scans such as TLS are that the data of the upper facades of the building cannot be collected due to the scanning location. The collection of data on the upper facades of the buildings with carrier platforms such as Unmanned Aerial Vehicles (UAV) that make it possible to take images from the air contribute to overcoming this problem. In this study, the data of the columns with complex structures in the archaeological site of Soli-Pompeipolis were collected and modeled using TLS and UAV photogrammetry methods. For modeling, a hybrid method was used by combining the data obtained by TLS and UAV photogrammetry methods. As a result of the study, 0.21 and 2.3 cm precise were obtained for point clouds produced by TLS and UAV photogrammetry, respectively. By combining the point clouds obtained from both data collection methods, 1.7 cm precise was calculated.
