Exploitation of hyperspectral data for infrastructures status assessment: Preliminary results of the istimes test bed

The paper presents the preliminary results of the experimental campaign conducted within the FP7 ISTIMES project. In particular the present paper deals with the exploitation of the ground based hyperspectral potentialities for detecting the conservation status of infrastructures, such as reinforced cement structures, roads, buildings, and architectural heritage. To exploit the effectiveness of hyperspectral technology, in situ measurements were carried out at the Montagnole (French Alpes) test site using the HySpex hyperspectral scanner (VNIR-SWIR) on a reinforced concrete beam solicited with different loading factors just to force the formation of a clear cracking structure within the concrete beam. The preliminary results obtained by the application of standard processing techniques, such as RX, MNF and change detection methods showed that suitable information are obtainable by processing hyperspectral data.
