摘要:Final aim of SIINDA research project is the development of an integrated system, composed by interagents hardware and software components, oriented to support the expert in the analysis and diagnosis of the conservation state of a monument. The complex phenomenon of degradation is studied considering the monument-environment system which is investigated by a "knowledge through images" approach. Therefore, more than one visualization technique of physical-chemical data on the three-dimensional reconstruction of surface monument is available. The three-dimensional model of the study case is, also, the interaction metaphor through which the user can select images and analyse the result of their processing. In fact the user is requested to interact in order to associate colorimetric properties of image regions to degradation typologies. Then extracted decay area are projected as visual effects on the three-dimensional model itself. Since all the acquired and processed data are collected in appropriate relational databases, the conservation state analysis is concluded by a user designed evaluation report which can be automatically produced. In this way, it is possible to obtain relevant information about both extension of different degradation typologies and eventual dangerous attainment of environmental threshold values. Among other, characterizing methodological choices to mention are: the development of innovative techniques for surface reconstruction, colour image correction and processing which allow objective and accurate analysis of degradation as preliminary step of a monitoring process, a multiscale and multidimensional approach for dealing and representing geometrical data and the realization of assistance tools for data acquisition and process
