V zadnjem obdobju se je pojavil trend naraščanja uporabe malih brezpilotnih letalnikov na različnih področjih civilne uporabe. Fotogrametrično snemanje z malimi brezpilotnimi letalniki omogoča pridobitev aeroposnetkov visoke prostorske ločljivosti za manjša območja, ki se lahko uporabijo za izdelavo fotogrametričnega oblaka točk in ortofota. V nalogi smo preizkusili uporabnost takšnega sistema za snemanje in izdelavo geodetskega načrta manjšega urbanega območja. Pri tem nas je predvsem zanimalo, katere detajle geodetskega načrta se iz tako pridobljenih podatkov lahko zajame, kje so prednosti in omejitve ter morebitne težave. Detajl smo zajemali iz fotogrametričnega oblaka točk s programom RiSCAN PRO v dveh korakih. V prvem koraku smo detajl zajeli zgolj iz fotogrametričnega oblaka točk, v drugem koraku pa smo si za interpretacijo vsebine pomagali z ortofotom. Naredili smo tudi primerjavo med zajetimi podatki iz fotogrametričnega oblaka in podatki terestričnega laserskega skeniranja. Po vseh korakih zajema smo izdelali geodetski načrt. Končne ugotovitve in oceno uporabnosti bližnjeslikovnih aeroposnetkov za izdelavo geodetskega načrta smo podali v zaključku.

• Title: Geodetic plan from close-range aerial images

Abstract

Over the last couple of years the usage of small UAV (unmanned aerial vehicles) in various fields of civilian use has grown extensively. Photogrammetric image acquisition with small unmanned aerial vehicles allows us to acquire high spatial resolution images of small areas, which can be used for the production of photogrammetric point clouds and orthophotos. In this graduation thesis we have examined the usefulness of a UAV system for data acquisition and the generation of a geodetic plan of a small urban area. We were focused to find out which details for the geodetic plan can be obtained from the data acquired by UAV, as well as to investigate the strengths, the limits and potential problems of the used method. The detail was acquired from the photogrammetric point cloud with the RiSCAN PRO software in two steps. In the first step, the detail was acquired only from the photogrammetric point cloud, in the second step, the orthophoto has been additionally used for interpretation of the contents. The comparison between the detail obtained from the photogrammetric point cloud and the data acquired by terrestrial laser scanning was done as well. After all these steps the geodetic plan was accomplished. Final observations and the evaluation of the usefulness of close-range aerial images for the generation of the geodetic plan are given in the conclusion.
