Comparison of forest attributes derived from two terrestrial lidar systems. [PDF]
, 2013 Terrestrial lidar (TLS) is an emerging technology for deriving forest attributes, including conventional inventory and canopy characterizations. However, little is known about the influence of scanner specifications on derived forest parameters.

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.

Terrestrial laser scanning in forest ecology: Expanding the horizon [PDF]
Remote Sensing of Environment, 2020 Terrestrial laser scanning (TLS) was introduced for basic forest measurements, such as tree height and diameter, in the early 2000s. Recent advances in sensor and algorithm development have allowed us to assess in situ 3D forest structure explicitly and revolutionised the way we monitor and quantify ecosystem structure and function. Here, we provide an

3D modelling of cultural heritage objects using video technology [PDF]
Biuletyn Wojskowej Akademii Technicznej, 2014 In the paper, the process of creating 3D models of St. Anne’s Church’s facades is described. Some examples of architectural structures inside of St. Anne’s Church’s are presented. Video data were acquired with the fixed focal length lens f = 16 mm.

QUALITY ASSESSMENT AND COMPARISON OF SMARTPHONE AND LEICA C10 LASER SCANNER BASED POINT CLOUDS [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2016 3D urban models are valuable for urban map generation, environment monitoring, safety planning and educational purposes. For 3D measurement of urban structures, generally airborne laser scanning sensors or multi-view satellite images are used as a data ...

Terrestrial Laser Scanning for Plot-Scale Forest Measurement [PDF]
Current Forestry Reports, 2015 Abstract Plot-scale measurements have been the foundation for forest surveys and reporting for over 200 years. Through recent integration with airborne and satellite remote sensing, manual measurements of vegetation structure at the plot scale are now the basis for landscape, continental and international mapping of our forest resources.

Radiometric correction of laser scanning intensity data applied for terrestrial laser scanning
ISPRS Journal of Photogrammetry and Remote Sensing, 2021 Abstract Alongside spatial information, an intensity scalar is also measured by LiDAR (Light Detection And Ranging) sensor systems. It corresponds to the amplitude of the backscattered laser beam after reflection on the scanned surface. This information isn’t directly usable due to dependencies of geometrical parameters occurring during the scanning ...

International Journal of Applied Earth Observations and Geoinformation, 2021 The development of devices capable of generating three-dimensional (3D) point clouds of the forest is flourishing in recent years. It is possible to generate relatively dense and accurate 3D data not only by terrestrial laser scanning but also mobile ...
