V nalogi smo se posvetili izvajanju enkratnih kontrolnih meritev, kjer smo primerjali dejansko geometrijsko obliko izdelka z njegovim referenčnim modelom. Pri reševanju problema smo uporabili metodo laserskega skeniranja. Predpostavili smo, da je zahtevano natančnost rezultatov najlažje dobiti z uporabo funkcije skeniranja pri elektronskem tahimetru, ki je časovno najbolj potratna. Želeli smo raziskati uporabnost metode terestričnega laserskega skeniranja pri kontrolnih meritvah modela, v primerjavi s trenutno uporabljeno metodo. Ugotovili smo, da je bila naša predpostavka pravilna in je za izvedbo tovrstnih kontrolnih meritev res najprimernejša uporaba elektronskega tahimetra. Rezultati doseženi z laserskim skenerjem so slabši, v rezultatih se pojavijo tudi anomalije, ki v resnici na merskem objektu niso prisotne.

Abstract

In this paper we focused on one time control measurements where we compared the actual geometric shape of the product with its reference model. We used the method of laser scanning. We assumed that the required precision of the results is easiest to obtain using the electronic tacheometer and its function of scanning, but this method is the most time consuming. However, we wanted to investigate the functionality of the terrestrial laser scanning method in model control measurements compared to the currently used method. We found out that our assumption was correct and that the electronic tacheometer is indeed the most suitable for performing such control measurements. The results achieved with a laser scanner are worse and anomalies which are not really present on the measurement object also appear in the results.
