Namen naloge je preveriti uporabnost aerofotografij, zajetih z daljinsko vodenega zrakoplova, za čim hitrejšo izdelavo načrtov prometnih nesreč. Časovno zamudno ročno merjenje razdalj za izdelavo načrta prometne nesreče je namreč eden od glavnih razlogov za daljše zastoje prometa. Predpostavljamo, da bi policisti z uporabo malega zrakoplova nalogo lahko opravili hitreje in z ustrezno kakovostjo. Simulirali smo prizorišče prometne nesreče, ki smo ga z upoštevanjem fotogrametričnih pravil na več različnih načinov fotografirali z zrakoplova. S klasičnimi geodetskimi meritvami smo izmerili oslonilne in kontrolne točke. Fotografije smo orientirali na različne načine, izdelali gost oblak točk in ortofoto območja nesreče, ki se lahko uporabi za izdelavo načrta prometne nesreče. Preverili smo natančnost izdelanih ortofotov, tako da smo izračunali relativno odstopanje med razdaljami na ortofotih in izmerjenimi razdaljami z geodetskim instrumentom. Ves čas izvedbe naloge smo izvajali različne analize vplivov kontrolnih razdalj in načinov aerofotografiranj na kakovost ortofota, kjer smo preverjali določene poenostavitve, ki smo jih uvedli, da bi kolikor se le da skrajšali čas zajema podatkov. Poiskali smo metodo, ki bi omogočala hitrejši način zajema podatkov, vendar tako, da bo kakovost končnega izdelka še vedno ustrezna.

• Title: Mapping of traffic accidents from photography taken by a remotely piloted aircraft system : master thesis

Abstract

The purpose of the thesis is to verify the usefulness of aerial photography from an unmanned aerial vehicle for faster production of traffic accidents plans. Time-consuming field measurement of data for the creation of a traffic accident plan is one of the main reasons for the long-term traffic jams. We assume that the police could use a small unmanned aerial vehicle to perform the task faster and with a proper quality. At a suitable location we simulated a traffic accident that was photographed in several different ways from the aircraft by taking into account photogrammetric rules. With classic geodetic measurements, we measured reference and control points. With appropriate software, we oriented our photos, made a dense cloud of points and an orthophoto of the accident area, which serve to create a vector plan. We verified the accuracy of orthophotos with a relative error, which was calculated between the distances determined on the ortophoto and on the field, with the surveying instruments. Throughout the execution of the thesis, we carried out various analyses of the impacts of control distances and ways of aerial photography on the quality of the orthophoto, where we checked the effect of shortening the time of data capturing. We found a method that will enable the fastest way of capturing data, but so that the quality of the finished product is still appropriate.
