Kurzfassung englisch:
In June 2010, the Dwelling Unit 7 of the Terrace House 2 in Ephesus, Turkey, was scanned from 172 scanning positions covering the object completely. Altogether, approximately 10 billion laser scanning points and a set of control points were acquired. In order to enable a global registration of the given datasets, we applied a robust 3D filtering method on the individual scans to reduce the amount data. After the registration, the points were merged to one point cloud by means of the same 3D filtering process. The main task of the project was the determination of 2D floor plans and sections and the generation of scaled projections of numerous walls for further archaeological interpretation. For this, we applied manual as well as automated methods. Within this contribution, we discuss the differences in quality and quantity of the two approaches. Special focus is drawn on the qualitative benefit of manual methods with respect to the quantitative benefit of the automated processing methods. While the manual analysis is based on commercial software tools, the automated processing is realized by innovative methods for data selection, projection and filtering in order to achieve the expected results. Additionally, hybrid approaches aiming at introducing as much automation as possible to support the manual work while ensuring high qualitative results are discussed. The conclusion of this contribution is that if large scale documentation of archaeological sites is to be performed, automated data processing is preferred over manual documentation for economic reasons, as long as certain restrictions on the achievable quality are acceptable. Automated processing serves as a reliable foundation for subsequent large scale interpretation of archaeological sites and higher repetition rates.
