Terrestrial laser scanning specifications

open access: yes, 2012
In recent years, the use of terrestrial laser scanners (TLS) has spread rapidly throughout the world, undoubtedly due to their survey speed and automation, but probably also for their novelty value. The technology has certainly influenced the improvement of previous well-known techniques (for instance, close-range photogrammetry), with the development ...

Terrestrial Laser Scanning Systems

2020
Laser scanning has become a part of the surveying practice during the last three decades of the development of scanning systems. Laser scanning technology is one of the most effective methods of spatial data acquisition and creation of 3D models in the present days.

Landslide site reconstruction with terrestrial laser scanning

2010 18th International Conference on Geoinformatics, 2010
The study of a landside site involves many aspects of data collection and data analysis activities. Among the data to be collected are the site location, the landside orientation, the soil profile, and the vegetation cover. Although these data (such as the topography and the distribution of trees) are 3-dimensional in nature, they are usually collected

Basics of Terrestrial Laser Scanning

2019
This chapter introduces the basic concepts of the automatic 3D surveying by means of laser scanning techniques, a methodology developed less than 20 years ago (see, e.g., Boehler et al. 2002) thanks to the technological improvement of the topographical instrumentations, in particular in the movement and in the electronical components.

Terrestrial Laser Scanning

2011
Since the early 2000s terrestrial laser scanning has evolved from a research and development (R&D) topic to a geo-data technology, which is commercially offered by a multitude of land surveying companies and other service providers all over the world. The technology is primarily used for the rapid acquisition of three-dimensional (3D) information of a ...

Target identification in terrestrial laser scanning

Survey Review, 2014
AbstractTarget identification is an important process in terrestrial laser scanner (TLS) measurements; however, due to strong competition between manufacturers, the design of laser scanners is kept secret and is usually strengthened by accompanying proprietary software. Moreover, the target identification algorithms (i.e.

Automatic Stem Mapping Using Single-Scan Terrestrial Laser Scanning

IEEE Transactions on Geoscience and Remote Sensing, 2012
The demand for detailed ground reference data in quantitative forest inventories is growing rapidly, e.g., to improve the calibration of the developed models of airborne-laser-scanning-based inventories. The application of terrestrial laser scanning (TLS) in the forest has shown great potential for improving the accuracy and efficiency of field data ...

Mesoscale Terrestrial Laser Scanning of Fluvial Gravel Surfaces

IEEE Geoscience and Remote Sensing Letters, 2011
Terrestrial laser scanning (TLS) point cloud data were gathered in the field of exposed gravel surfaces for sampling sites with a spatial extent of 6m × 6m. We propose in this letter a novel two-stage mean-based filter scheme for processing the point cloud to generate the digital surface model (DSM) at a resolution of 1 cm.
