Architectural Historical 4D Documentation of the Old-Segeberg Town House by Photogrammetry,Terrestrial Laser Scanning and Historical Analysis

摘要

Education for the own present and future can be made by the examination of history. The architectural historical documentation of the Old-Segeberg town house shows one approx. 500 years civil housing tradition in a replica of an approx. 475 years old house, both being essentials parts of the 800-year history of the city Segeberg. This historic town house is one of the oldest secular buildings in Schleswig-Holstein (Germany) and has substantial value for the city's own history. In 2011 the building was geometrically recorded in detail, internally and externally, with modern 3D data acquisition methods such as digital architectural photogrammetry, panorama photography and terrestrial laser scanning. From the recorded geo-data a 3D CAD model was generated, which shows both the interior and the external area of the town house. On the basis of historical analysis six construction phases of the building have been historically proven and in CAD modelled. These epochs document the different additions and renovations in the CAD model, which were carried out over the centuries. Now these different construction phases of the building can be viewed and analysed in 4D using a specific free viewer. Additionally, a virtual tour was generated from the panorama photographs, which permits a simple and detailed visualisation of the building from the inside and outside for all interested users on the Internet. The 3D model of the current building was photo-realistically textured, including the neighbouring houses and the environment using CINEMA 4D, with the result that video sequences and an interactive visualisation have been generated. The multimedia representation of the building offers both interested visitors and expert professionals an exciting time-historical view of the town house both in the museum and over the Internet.
