Environmental influences on the stability of a permanently installed laser scanner

The advancement of permanently measuring laser scanners has opened up a wide range of new applications, but also led to the need for more advanced approaches on error quantification and correction. Time-dependent and systematic error influences may only become visible in data of quasi-permanent measurements. During a scan experiment in...

Error budget of terrestrial laserscanning: Influence of the intensity remission on the scan quality

Terrestrial laser scanning (TLS) is a surveying technology to measure distances to surfaces in the spherical surrounding of the scanner instrument. In contrast to pulse, i.e. time of flight scanners, phase based scanners emit a modulated wave signal that allows for determining the object distance from the returned phase pattern. Because of their...
