Terrestrial laser scanner is a kind of fast, high‐precision data acquisition device, which had been more and more applied to the research areas of forest inventory. In this study, a kind of automated low‐cost terrestrial laser scanner was designed and implemented based on a two‐dimensional laser radar sensor SICK LMS‐511 and a stepper motor. The new scanner was named as BEE, which can scan the ...

Systematic trends are apparent when studying the self-calibration residuals of many modern static terrestrial laser scanners. Since the operation of terrestrial laser scanners is comparable to an efficient robotic total station, the sensor modelling parameters are developed in the spherical coordinate system where the raw observables of the scanner are range, horizontal angle, and vertical angl...

The paper presents the integration of a geometric model of fisheye lenses and a geometric terrestrial laser scanner model in a bundle block adjustment. The model allows for a full integration of hemi-spherical fisheye imagery into terrestrial laserscanner data processing schemes. Both the laserscanner and fisheye geometric model are extended by additional parameters to compensate for deviations...

Automatic registration, classification and segmentation of Terrestrial Laser Scanner (TLS) data are of great interest in Geoinformatics & Autonomous vehicle research. Along with dense and accurate 3D geometric data, laser scanners also collect return intensity information. Inclusion of this spectral information has potential to improve the working of the above mentioned processes. However, thes...

There are numerous imaging modalities for reconstructing 3D object space on the market. Among all the varieties, which include 3D TOF range cameras, structured light systems, and traditional photogrammetric systems, terrestrial laser scanners have gained the most attention and demand from the surveying and engineering discipline. This is probably because of the large field of view and rapid den...

Terrestrial laser scanners and digital cameras can be considered largely complementary in their properties. Several instruments combine a laser scanner and a camera, with the laserscanner providing geometry information and the camera supplying point of surface colour. These approaches of data fusion make sub-optimal use of the complementary properties of the two devices, as they assign a master...
