Terrestrial Laser Scanner (TLS) Equipment Calibration

This study's aim is to develop the measurement procedures to evaluate the quality of the observations made using TLS equipment. In addition, it seeks to estimate an uncertainty value allowing the users to know the reliability of the instrument measurements. The intention is to describe a working reproducible methodology without the need for a very complex infrastructure and based on ISO criteria.To achieve this, several TLS equipment based on different measurement principles were used. This study provides a good approach to the repeatability and reproducibility of the measurements to determine how the different measurements of the same measurand match.
