Virtual sensors to support the monitoring of cultural heritage damage

The present work is part of a wider research activity carried on within the Italian National Project named SIINDA. It shows how physical atmosphere parameters like temperature, humidity, wind direction, can be indirectly estimated in specific points of the monument, if one, or more than one, ambient air monitoring station is present in the neighborhood of the monument itself. We use a connectionist system trained to map the parameters measured by such stations with the parameters measured by the set of installed sensors. The obtained results look like very good and we received the approving by cultural heritage experts who evaluated such a methodology to effective by support monitoring in the field of the conservation state of monuments.
