Abstract

A multisensor approach seems to be the most suitable solution for complex environment modeling. In this paper such an approach was exploited to generate a model, capable of covering different interesting aspects of the church of San Francesco al Prato, in Perugia (Italy). It is one of the main churches of the city, reconstructed around the middle of XVIII century over a previous church, and enriched in the centuries with masterpieces by such artists as Perugino or Raffaello. Unfortunately, due to some earthquakes its structure suffered several major lesions, as for example the loss of the roof, and the recent decision to restore it led to the need for an accurate survey. The procedures adopted for documenting this building and some preliminary results are described here. Due to its interesting aspects, the work was concentrated on the transept-apse complex, characterized by a complex spatiality, different building materials, a marked architectural decay, and a geological instability of the underlying ground that produced cracks and lesion all over the structure. Topographic and digital photogrammetric tecniques have been employed in order to obtain complete and accurate data; 3D laser scanner has been employed only on the transept. The model has been obtained from the merge of the different acquisition. The documentation of such a complex architectural space was planned according to progressive levels of critical synthesis; the surveying approach described here followed the same logic and allowed us to obtain a three-dimensional model of the structure under investigation, by adapting the space resolution to the complexity of the surface or to the historical and artistic interest. Such tradeoff involved also the optimization of fundamental resources such as acquisition time or computer memory space, that have to be carefully taken into account in order to make any high complexity surveying project feasible.
