For high accuracy requirements, the scanners become the main sensor group because of their geometric precision and reliability. To guarantee reliable survey results, specific calibration procedures have to be applied, which can be divided into the scanner sensor calibration as step 1, and the ...
Monitoring by means of surveying methods consists of taking repetitive geodetic measurements of the grid of measurement points that have been previously stabilised in the studied area. It is important to choose the location of measurement points – they should be located in areas where activity ...
Cultural heritage recording and engineering surveying are prime applications for terrestrial laser scanners (TLSs) because of the high spatial resolution, ... DD Lichti,SJ Gordon,T Tipdecho - 《Journal of Surveying Engineering》 被引量: 299发表: 2005年 Terrestrial laser scanner to detect landslide...
In order to validate the accuracy of the terrestrial laser scanners used in the surveying projects, laboratory measurements were carried out. To investigate the root-mean-square error (RMSE) of the laser scanner ranging, the deformation of a steel plate was measured. The displacements were also m...
Today, laser scanners are widely used in the field of architectural, archaeological, and environmental surveying (Figure 2, Figure 3, Figure 4, Figure 5, Figure 6). With its automated data capture capabilities, it is bringing new perspectives and can satisfy most requirements of those types of...
Laser scanners operate in either (i) stationary mode or (ii) mobile mode. In stationary mode, laser scanners are typically installed on a tripod, while in mobile mode, laser scanners can be handheld, vehicle-mounted, robot-mounted, or aircraft-mounted. Laser scanning photogrammetry is an ...
These are 10, of the many, reasons to consider laser scanners for a forensic application: 1) Easy to use: Many manufacturers are moving toward a simpler interface making operation of the scanner more like a digital camera than a complicated survey instrument. 2) Portability: Laser scanners are...
39% of the discomfort/injury cases were caused by cosmetic treatments, 26% were caused due to laser pointers, and 34% were caused by "other" which included surveying tools, entertainment lasers, materials processing, and scanners.The study analyzed published eye injury case reports since 1999, ...

topography (Earth)/ terrestrial laser scannerslarge complex landformsTerrestrial laser scanners (TLS) allow large and complex landforms to be rapidly surveyed at previously unattainable point densities. Many change detection methods have been employed to make use of these rich data sets, including cloud...
