| Summary: | In this paper, a Cultural Heritage survey, performed by employing and integrating different type of acquisition technologies (imagebased
and active sensor based) is presented. The aim of the survey is to create a 3D multiscale database, therefore, different
restitution scales, from the architectural-urban one to a detail one are taken in consideration. This research is part of a project
financed by the Unesco for the study of historical gardens located in Mantua and Sabbioneta, and in particular for the <i>Palazzo Te</i>
renaissance gardens in Mantua, which are reported in this paper. First of all, a general survey of the area has been realized by
employing the classical aerial photogrammetry in order to provide the actual arboreal and urban furniture conditions of the gardens
(1:500 scale). Next, a detailed photogrammetric survey of the Esedra courtyard in <i>Palazzo Te</i> has been performed by using a UAV
system. At the end, laser scanning and traditional topography have been used for the terrestrial detailed acquisition of gardens and
architectural façades (1:50–1:20 scale). The aim of this research is to create a suitable graphical documentation support for the study
of the structure of the gardens, to analyze how they have been modified over the years and as an effective support for eventual future
re-design. Moreover, the research has involved a certain number of botanic and archeological investigations, which have been duly
acquired and modeled with image based systems.<br><br>
Starting from the acquired datasets with their acquisition scales, a series of comparative analysis have been performed, especially for
those areas in which all the systems have been employed. The comparisons have been extracted by analyzing point cloud models
obtained by using a topographical network.<br><br>
As a result, the multi-range approach efficiency, obtained by employing the actual available technologies have been illustrated in the
present work. |
