Full-waveform terrestrial laser scanner, amplitude, wetnessAbstrakt
Full-waveform terrestrial laser scanning is a recent technology which is able to digitize and record the complete waveform of the backscattered echo. It gives additional information about the structure and physical backscattering properties of the illuminated surface (reflectance and geometry). Some authors focus on the data quality of a terrestrial laser scanner. Most of them are interested in the geometrical accuracy of the scanner (errors of instrumental axis, range accuracy using target, etc.). In this paper, the influence of different materials on the recorded measurements of a full-waveform terrestrial laser scanner (FW - TLS) VZ – 400 was studied. The measurements were focused on the materials used at buildings facades (wood, concrete and plaster), different coloured sheets and several minerals.
