Image sensing for Agricultural, Cultural Heritage and NDT applications

Image sensing for Agricultural, Cultural Heritage and NDT applications

Description of the activity

The research activity is aimed at developing new analysis and diagnostic methodologies mainly based on the use of imaging technologies. In the activity using cameras and instruments of the Thermography and Infrared Imaging Laboratory of the ISASI-CNR, operating in the infrared regions: NIR, SWIR, MWIR and LWIR, are developed Image Sensing systems that allow a non-invasive analysis useful for applications in the fields of precision agriculture, cultural heritage and non-destructive diagnostics (NDT). The analysis is performed both with a passive approach, monitoring the sample in the conditions of natural light to which it is normally subject, and with different active approaches (Lock-in, PT, PCT, etc.), studying its behaviour before, during and after being stimulated with sources (coherent and non-coherent) in the spectral regions ranging from UV to NIR. The information achieved from this type of investigation allows both to implement new analysis systems based on the images useful for monitoring the structural properties of the sample, and to study its functional response to different light stimuli, contributing to the scientific understanding of the mechanisms governing such responses. Part of the research activity concerns the development of ad-hoc operational protocols and the realization of home-made analysis procedures through the use of MATLAB constructs or the C ++ language.
