Abstract

The purpose of this work is to defi ne a methodology for the use of video sequences as a source of metric data to obtain three-dimensional models in a reliable and fast way, as well as a virtual environment for the representation, fruition and communication of the fi lmed architectures. An important investigation topic will be the analysis of the metric data provided by the use of informatic tools. For this intent verifi cations will be based on two key features: data’s accuracy and their precision. In the fi rst case the compliance to the real metric measurements will be checked by comparing our data with those provided by other techniques already verifi ed and consolidated while, in the second case, the scattering of the achieved results will be verifi ed by repeating several times the algorithm. The experiment will be held using software and optical instruments selected in order to obtain a good balance between costs and quality. This methodology makes it possible to work virtually on an urban context or a specifi c architectural structure. Thanks to many possible simulations, it may be useful in various fi elds of application such as survey and restoration, monitoring, remote fruition, virtual reconstruction and simulation of possible interventions. The fast data acquisition end the easy further processing make this technology easily and effi ciently applied on various cultural heritage such as architecture, archaeology and urban contexts. The output of this workfl ow leads to a better communication with the fi nal user providing enhanced immersive experience and easier comprehension then traditional static images (rendering, 2d elaborations, photo-manipulation etc.) adding an important feature: motion. Therefore it is also intended as a valid tool for users who are not very familiar or specialized in this field.
