Determining Variance-Covariance Matrices for Terrestrial Laser Scans: A Case Study of the Arch Dam Keasurements acquired within different epochs serve as the basis for deformation analysis. The uncertainty information of these observations is generally established. When referring to surface-based deformation monitoring, terrestrial laser scanning (TLS) is intensively hyped up. Nevertheless, curren

Assessing the Temporal Stability of Terrestrial Laser Scanners During Long-Term Measurementsithin this field, often long-term measurements are acquired, for which the temporal stability of the laser scanner’s observations need to be assured or at least its magnitude and influence factors should be known. While these influence factors have been investigated for most of the geo-sensors takin

Quantification of Systematic Distance Deviations for Scanning Total Stations Using Robotic Applicatih-precision surveying tasks in the field of engineering geodesy. For the determination of these distance deviations, an approach is introduced, which is based on the absolute comparison between reference measurements and laser scans. However, the implementation of the developed method, which reveals

Testing Capabilities of Locata Positioning System for Displacement Measurementsn indoor environment in general. In 2003 Locata Corporation from Australia began with the development of a new, completely independent technology called Locata, which was designed to overcome the limitations of GNSS. The paper will display capabilities of Locata positioning system for determining si

A priori vs. In-situ Terrestrial Laser Scanner Calibration in the Context of the Instability of Calin task. Such approaches presume the stability of errors with time and external influences so that the calibration parameters are valid at future measurements. Alternatively, TLSs are calibrated in-situ during the measurement. Then, there is no need to assume the stability of the calibration paramete

Analysis of Warm-up Effect on Laser Tracker Measurement Performanceprecision is required in determining their shape and parameters. At present, coordinate measuring systems—laser trackers—are often used to determine the dimensions of these components, with precision up to tens of micrometers. If a measurement result with such high precision is requested, factors th
