Abstract

Razvoj brezpilotnih letalnikov je spremenil potek dela na različnih področjih, posebej v geodeziji, v kateri bližnjeslikovno aerofotografiranje in aerolasersko skeniranje predstavljata nove, hitrejše in učinkovitejše načine zajema prostorskih podatkov. Ob tem je pomembno, da se uporabnik zaveda prednosti in slabosti omenjenih metod. Pri geodetskih nalogah lahko kombiniramo različne tehnike izmere, npr. poleg klasične terestrične izmere in metode izmere GNSS RTK uporabimo še podatke, pridobljene z brezpilotnim letalnikom in pri aerolaserskem skeniranju. V diplomski nalogi smo primerjali višinske razlike med tremi metodami izmere na treh različnih deloviščih. Med seboj smo primerjali višinska odstopanja klasične terestrične izmere, bližnjeslikovnega aerofotografiranja in aerolaserskega skeniranja. Koren srednjega kvadratnega pogreška višinskih razlik med terestrično metodo izmere in brezpilotnim letalnikom je na vseh treh deloviščih znašal povprečno 0,05 metra, medtem ko je med terestrično izmero in aerolaserskim skeniranjem znašal povprečno 0,16 metra.

Secondary title: Analysis of height differences between terrestrial geodetic survey, close-range aero photogrammetry and airborne laser scanning
Secondary abstract: Development of UAVs (ang. unmanned aerial vehicles) has changed everyday work routine in different professions, especially in geodesy, where close-range aero photogrammetry and airborne laser scanning (ALS) present new opportunities and methods in the meaning of faster and more efficient collection of spatial data. As with every technology, there are also some advantages and disadvatanges that users need to be acquainted with. It is important, that we combine different geodetic methods (classic geodetic survey, GNSS-RTK method, close-range aero photogrammetry, ALS) for best results. We have analysed height differences between three methods on three different worksites and compared results that were delivered from terrestrial geodetic survey, aero photogrammetric point cloud and ALS point cloud. RMSE of height differences between terrestrial geodetic survey and close-range aero photogrammetry was on average 0,05 m. Between terrestrial geodetic survey and airborne laser scanning was on average 0,16 m.
