Abstract

Urban material discrimination and other infrastructure assessment can be difficult to perform remotely. Polarimetry has been shown to aid in discriminating between material classes, but only recently has been studied in the context of discrimination within classes of construction materials. We present new results focused on discriminating between nine concrete materials. The materials were illuminated at varied elevation angles at visible and near-infrared wavelengths and imaged from nadir. We show that analyses of multispectral polarimetric images can provide useful discrimination where multispectral images alone cannot.
