The multi sensor system carried is composed of three cameras: i) multispectral camera with 9 sensors that, using band-pass filters, acquire at 8 bands of the electromagnetic spectrum (plus RGB), comparable to the VIS-NIR bands acquired by the Worldview2 satellite; ii) radiometric thermocamera with the following characteristics: Frequency 30Hz, 640 640 x 512 resolution, Optic (13mm; 19mm); iii) multispectral camera acquiring at 4 bands, plus RGB at in the visible spectrum. The cameras i) and ii) are mounted on a drone DJI MATRICE 600 PRO, whereas the camera iii) is installed on Parrot AG Disco Pro (fixed wings).
Potential Results
This system allows to obtain high resolution RGB orthophotos, terrain models and multispectral maps that facilitate the identification of proxy indicators of archaeological interest. In particular the digital models allow to recognize microtopographic details of archaeological interest related to the presence of buried and shallow structures archaeological interest. The images acquired at red and NIR bands emphasize crop-marks and humidity variations of archaeological interest. Radiometric thermal camera can be useful in detecting archaeological features produced by contrast in thermal inertia and evapotranspiration stress of vegetation.
