INFLUENCES OF RANGE AND INCIDENCE ANGLE ON MEASUREMENTS OF A FULL-WAVEFORM TERRESTRIAL LASER SCANNER VZ - 400

Abstract

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. Some of them are interested in the influence of the materials on the measurements of a full-waveform terrestrial laser scanner. Most of them are interested in the geometrical accuracy of the scanner (errors of instrumental axis, range accuracy using target, etc.). The aim of this article is to find out the influences of target geometry on the measurement of the full waveform terrestrial laser scanner VZ – 400. The emphasis was put on the influence of range to target and incidence angle.
