STEM MODELING FROM TERRESTRIAL LASER SCANNING USING THE BLOCK MINIMUM APPROACH

open access: yesRevista Brasileira de Cartografia, 2015
Terrestrial laser scanner is widely used in forestry surveys to map and estimate tree dimensions. The main problem is still how to reconstruct the tree geometry from the laser scanner point cloud.

THE EFFECT OF OBJECT SURFACE COLORS ON TERRESTRIAL LASER SCANNERS

open access: yesInternational Journal of Engineering and Geosciences, 2017
The terrestrial laser scanning systems are a relatively new measurement technology. Along with technological advances, these systems are gaining popularity and have been increasingly used in many different fields. With terrestrial laser scanning technology, three- dimensional (3D) information and images of objects can be obtained more practical, easy ...

Dual-Antenna Terrestrial Laser Scanner Georeferencing Using Auxiliary Photogrammetric Observations

open access: yesRemote Sensing, 2015
Terrestrial laser scanning typically requires the use of artificial targets for registration and georeferencing the data. This equipment can be burdensome to transport and set up, representing expense in both time and labor. Environmental factors such as

Radiometric Calibration of Terrestrial Laser Scanners with External Reference Targets

open access: yesRemote Sensing, 2009
The intensity data produced by terrestrial laser scanners has become a topic of increasing interest in the remote sensing community. We present a case study of radiometric calibration for two phase-shift continuous wave (CW) terrestrial scanners and discuss some major issues in correcting and applying the intensity data, and a practical calibration ...

Intensity Data Correction for the Distance Effect in Terrestrial Laser Scanners

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2016
Terrestrial laser scanning systems deliver geographic coordinates and backscattered intensity values, which are acknowledged as significant observations that can be used in a wide range of applications. However, the direct use of these original intensity data is not recommended because they are influenced by multiple variables, especially distance and ...

Registration of Point-Clouds from Terrestrial and Portable Laser Scanners

open access: yesInternational Journal of Automation Technology, 2016
We proposed a registration method for aligning short-range point-clouds captured using a portable laser scanner (PLS) to a large-scale point-cloud captured using a terrestrial laser scanner (TLS). As a PLS covers a very limited region, it often fails to provide sufficient features for registration.
