Angular resolution of terrestrial laser scanners

The Photogrammetric Record, 2006
AbstractKnowledge of a laser scanner's spatial resolution is necessary in order to prevent aliasing and estimate the level of detail that can be resolved from a scanned point cloud. Spatial resolution can be decoupled into range and angular components.

Uncertainty Assessment in Terrestrial Laser Scanner Measurements

Key Engineering Materials, 2014
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.

Automatic Deformation Acquisition Using Terrestrial Laser Scanner

Applied Mechanics and Materials, 2011
Deformation monitoring is typically undertaken using spare, point-wise geodetic surveying techniques, such as total station or GPS. Deformation monitoring using terrestrial laser scanning is gaining considerable attention mainly due to the high spatial resolution of the acquired data. It can provide dense 3D information of the surface of an object.

Simple Terrestrial Laser Scanner for Measuring Streambank Retreat

Journal of Hydraulic Engineering, 2016
AbstractHigh-resolution measurements of streambank retreat (SBR) rates are important for engineering applications, such as infrastructure planning and stream restoration. Conventional methods of measuring SBR, such as erosion pins or total stations, lack sufficient point density to accurately capture the spatial variability of bank retreat over an ...

Condition Assessment of Bridges Using Terrestrial Laser Scanners

Structures Congress 2015, 2015
Assessing the current condition of structures and infrastructure systems has long been critical to ensure their effectiveness and remaining life. Even though nondestructive evaluation technologies have improved significantly, visual inspection is still a main tool used to assess the condition of structures, especially bridges.

Terrestrial Laser Scanner Surveying in Coastal Settings

2014
Over the last decade, there has been a proliferation of commercially available tripod-mounted Terrestrial Laser Scanner (TLS) systems that use the phase difference or the time-of-flight of emitted pulses of light to rapidly acquire high-density topographic and surface reflectance data.
