Ocena uporabnosti tehnologije Apple Iphone Lidar za izmero dreves na vzorčnih ploskvah gozdne inventure [Elektronski vir] : diplomsko delo - univerzitetni študij - 1. stopnja = Usability of Apple iPhone lidar technology for surveying trees in forest inventory sample plots : B. Sc. Thesis - academic study programmesKrižaj, JakaLasersko skeniranje gozda s terena je koristna tehnologija za dopolnitev in overitev informacij, pridobljenih s terenskim zajemom podatkov v okviru klasične gozdne inventure. Lidarski skenerji te ... vrste so zaenkrat še dragi in zahtevajo usposobljene uporabnike. Zato je v diplomski nalogi preizkušena uporabnost komercialne tehnologije Apple iPhone lidar, in sicer za pridobivanje dveh poglavitnih informacij o drevesih na vzorčnih ploskvah gozdne inventure; to sta prsni premer drevesa in oddaljenost drevesa od središča ploskve. Na štirih trajnih krožnih raziskovalnih ploskvah na Rožniku so bili izmerjeni referenčni podatki najprej s klasičnimi metodami (merski trak za prsni premer in Vertex Laser Geo za merjenje azimutov ter razdalj za lokacijo drevesa), nato pa še z lidar-opremljeno Apple iPhone 13 Pro Max napravo. Podatki so bili obdelani z odprtokodnima programoma CloudCompare in R. Ugotovljeno je bilo, da so vrednosti prsnega premera, pridobljenega iz podatkov laserskega skeniranja, v povprečju precenjene za 1,49 cm (RMSE = 2,68 cm), napaka pa je značilno večja pri tanjših drevesih. Horizontalne razdalje so bile večinoma podcenjene, v povprečju za 7,1 cm (RMSE = 24,7 cm). Napaka v horizontalni razdalji z naraščajočim časom skeniranja narašča, medtem ko trajanje skeniranja ne vpliva na vrednosti prsnih premerov.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [J.
