magistrsko delo
Povzetek
V magistrskem delu je predstavljena nova metoda za določitev geometrije tirnic žerjavne proge, in
sicer na podlagi meritev s terestričnim laserskim skenerjem in z izdelanim računalniškim programom,
ki na osnovi oblaka točk tirnic določi horizontalni in vertikalni potek žerjavne proge. Metodo smo
testirali na žerjavnih progah hidroelektrarne Krško in termoelektrarne Brestanica, za kateri smo po
skeniranju iz oblaka točk ekstrahirali zgornjo in stransko notranjo ploskev glave tirnic. Posamezno
žerjavno progo smo razdelili na segmente, skozi katere smo izravnali ravnine in določili
karakteristične linije tirnic. Na osnovi profilov smo med karakterističnima točkama na istem profilu
določili položajne in višinske odmike tirnic, dejanski razpon in višinsko razliko med tirnicama
žerjavne proge in preverili, ali so izračunani parametri geometrije skladni s predpisi, ki jih določa
obravnavan standard. V nalogi smo tudi raziskali, kako se parametri geometrije tirnic, ki so določeni z
metodo terestričnega laserskega skeniranja, ujemajo s parametri, določenimi s klasično polarno
metodo detajlne izmere. Prav tako smo tudi testirali, kako na določitev parametrov vpliva dolžina
segmenta in gostota točk tirnic. Na osnovi ugotovitev, do katerih smo prišli med izdelavo naloge, smo
podali določene smernice za kakovostno določitev geometrije tirnic žerjavne proge s tehnologijo
terestričnega laserskega skeniranja.

Control measurements of crane rails using terrestrial laser scanning |
Sekundarni povzetek: |
The master's thesis presents a new method for crane rail geometry determination, i. e. based on
measurements obtained by using a terrestrial laser scanner and a dedicated computer programme
which, on the basis of the rail points cloud, determines the horizontal and vertical path of the crane
rail. The method was tested on the crane rails of Krško Hydroelectric Power Plant and Brestanica
Thermal Power Plant, where, after scanning the point cloud, the upper and the lateral internal surface
of railheads was derived. Each crane rail was divided into segments, through which the planes were
fitted and the characteristic rail lines were determined. Based on the profiles, positional and height rail
offsets were determined between the characteristic points on the same profile, as well as the actual
span and the height difference between the crane rails. Furthermore, it was verified whether the
calculated geometry parameters complied with the rules set by the standard in question. The thesis also
examined how the rail geometry parameters – as determined by the terrestrial laser scanning method –
correspond with the parameters determined by the classical polar method of surveying. Furthermore, it
was tested how the determination of patterns is influenced by the length of the segment as well as the
density of rail points. Based on the conclusions drawn during the elaboration of this thesis, certain
guidelines are given on how to ensure the quality of crane rail geometry determination using terrestrial
laser scanning technology. |
