Uncertainty Assessment in Terrestrial Laser Scanner Measurements

Abstract. The essential purpose of this study is to develop the measurement procedures in order toevaluate the quality of the observations carried out using Terrestrial Laser Scanner (TLS) equipment.It tries, in addition, to estimate an uncertainty value that allows the users to know the reliability of theinstrument measurements. The fundamental idea of this paper is to show the metrological control'sneed, and the quality of measure's evaluation for TLS equipment and to describe a working methodology,able to be reproducible, without the essential need of having a very complex infrastructure.
