ACQUISITION, MODELING AND GIS INTEGRATION OF A 3D MODEL OF THE FRAME OF XVI TH CENTURY HISTORIC BUILDING

The aim of the project described in this paper was to define a three level frame survey mode of an old building: the so called “Andlau’s Seigneury”, Alsace, France. Two different techniques were compared for the data acquisition: 3D TLS and point extraction and classical surveying with a total station. According to them, different modeling processes were also defined for the creation of a 3D virtual model of the frame. The data were structured and the model was created to be used for an interactive animation in a museum. The different steps of the project can be described as follow: 1/ definition of a identification system of the frame beams and understanding of the frame structure, 2/ comparison and adaptation of two data acquisition methods to the particular context, 3/ design of a GIS model including complementary information like photographs, size, specific attributes. The final modeled frame was then integrated in the 3D model of the entire building. RESUME :
