Uporaba fotogrametričnega oblaka točk za izračun količine okroglega lesa na tovornjakih : magistrsko delo : magistrski študij - 2. stopnja = Using a photogrammetric point cloud to calculate the volume of roundwood on trucks : M. Sc. Thesis : Master Study ProgrammesAndrejčič, AnejV juniju 2018 smo izvedli raziskavo o uporabi fotogrametrije za izračun volumna lesa na tovornjakih. Raziskava je bila izvedena na območju GGE Javorje. Po poseku smo sortimente izmerili in jih ... razdelili v tri debelinske razrede. V raziskavo so bili vključeni le sortimenti s premerom nad 10 cm in dolžino 8,25 m. Vsak debelinski razred smo postopoma nalagali na tovornjak in vmes izvajali snemanja (skupno 30 posnetkov) z brezpilotnim letalnikom. Dobljene posnetke smo nato obdelali s programom Pix4D in programom Microsoft Excel. Za izračun volumna iz 3D modela lesa smo uporabili metodo triangulacije. Med izračunanim volumnom iz 3D modela lesa in izmerjenim volumnom lesa so nastajala odstopanja od -1,07 m3 do 0,55 m3. V debelinskem razredu A je znašal povprečni faktor zlaganja 0,54 % 0,04, pri debelinskem razredu B in C pa 0,54 % 0,02. Pri polnem tovornjaku je bil največji faktor zlaganja v debelinskem razredu B (0,59), sledi debelinski razred A (0,58) in debelinski razred C (0,57). Glede na dobljene rezultate menimo, da bi prilagojeno metodo brez težav uporabljali tudi v praksi.Type of material - master's thesis ; adult, seriousPublication and manufacture - Ljubljana : [A.
