Terestrično lasersko skeniranje, je novejša tehnologija, ki se v geodeziji vedno več uporablja. Zmožnosti tehnologije za uporabo v geodeziji niso dovolj dobro poznane. Zato smo to tehnologijo primerjali z preverjeno tehnologijo klasične tahimetrične geodetske izmere. Testno polje je bila geodetska mreža za opazovanje stabilnosti gradbene jame Bavarski dvor. Mreža opazovalnih točk je bila izmerjena s preciznim tahimetrom in terstričnim laserskim skenerjem. Koordinate diskretno merjenih točk klasične mreže smo pridobili z ločeno izravnavo horizontalne in višinske mreže. Koordinate točk izmerjene z laserskim skenerjem so bile podane v koordinatnem sistemu skenerja, zato smo jih, da smo lahko izvedli primerjavo, morali transformirati v lokalni sistem terestrične mreže gradbene jame.

• Title: Comparison of TPS and TLS measurements of geodetic net Bavarski dvor

Abstract

Terrestrial laser scanning is a new technology which is in recent times more commonly used in geodesy. The possibilities of this technology in geodesy are therefore not yet widely known. That is why we compared this technology with the verified technology of a classical geodetic terrestrial survey. The test field was the geodetic grid for the observation of the stability of the construction pit in Bavarski dvor. The grid of measurement points was measured with a precise total station and a terrestrial laser scanner. The coordinates of discreetly measured points were gathered with a separate adjustment of the horizontal and vertical grid. The coordinates of points that were measured with the laser scanner were only available in the coordinate system of the scanner. To be able to compare the results, they first had to be transformed into a local system of a terrestrial grid of the construction pit.
