Student thesis: Master's Thesis


Terrestrial Laser Scanning (TLS) intensity data can be regarded as the relative reflectance of the surface material TLS intensity is a function of the angle of incidence of the laser beam the range distance between the laser and the surface and the surface type The Bidirectional Reflectance Distribution Function (BRDF) was used to describe the relation between the angle of incidence and TLS intensity Five remote sensing semi-empirical BRDF models including Rahman–Pinty–Verstraete (RPV) model and four kernel-driven models derived from Ross (1981) were evaluated using twelve flat sample materials The goodness of fit of the BRDF models to the TLS intensity are evaluated based on visual examination of the fitted trend and their corresponding coefficients of determination The results show that the Rossthin-Roujean model and RPV model are the most suitable for TLS data
