Abstract

Ker je na trgu vedno večja ponudba daljinsko vodenih letalnikov RTF, se pogosto postavljata vprašanji, kateri so sposobni zajetja dovolj točnih podatkov za uporabo pri načrtovanju v določenem prostoru in kakšne razlike v kakovosti zajetih podatkov lahko pričakujemo med različnimi modeli. V diplomskem delu se osredotočamo na primerjavo točnosti zajetih podatkov dveh daljinsko vodenih letalnikov, in sicer DJI Mavic Air 2 in DJI Phantom 4 Pro. Meritve na terenu smo opravili na območju zemeljskega plazu Slano Blato, nad Lokavcem pri Ajdovščini. Podatke smo z obema letalnikoma pridobili s treh višin, in sicer s 60, 90 in 120 m. Med seboj primerjamo daljinsko vodena letalnika glede na ravninsko in višinsko točnost zajetih podatkov. Ugotovimo, da so posnetki ortofoto in digitalni modeli površja, pridobljeni s Phantom 4 Pro, višje ločljivosti kot tisti, pridobljeni z Mavic Air 2. Povprečne vrednosti RMSE so pri posnetkih Phantom 4 Pro manjše, saj so znašale manj kot 1 cm. Vrednosti RMSE pri Mavic Air 2 so znašale od 0,032 m do 0,040 m. Oba letalnika sta s tem dosegala nekaj centimetrsko točnost, kljub večji položajni točnosti Phantom 4 Pro. Napake zajema po koordinatnih oseh primerjamo z dvosmerno analizo variance ANOVA, kjer ugotovimo, da obstajajo med daljinsko vodenima letalnikoma statistično značilne razlike. Te se kažejo v ravninski in višinski točnosti, kjer se Phantom 4 Pro izkaže za bolj točno alternativo.

Secondary title: Positional accuracy of photogrammetric products of various remotely controlled aircrafts RTF
Secondary abstract: As there is a growing supply of remotely piloted aircraft RTF on the market, it is often asked which are capable of capturing sufficiently accurate data for use in the design of a particular space and what differences in the quality of the data covered can be expected between different models. The thesis focuses on comparing the accuracy of the data captured by two remotely piloted aircraft, namely DJI Mavic Air 2 and DJI Phantom 4 Pro. Field measurements were made in the area of the Slano Blato landslide, above Lokavec near Ajdovščina. Data was obtained from three altitudes with both aircraft, from 60, 90 and 120 m. We compare remotely piloted aircraft according to the plane and altitude accuracy of the data captured. We find out that the orthophoto imagery and digital surface models obtained by the Phantom 4 Pro are higher in resolution than those obtained by Mavic Air 2. Average RMSE values are lower for Phantom 4 Pro recordings, at less than 1 cm. RMSE values for Mavic Air 2 ranged from 0,032 m to 0,040 m. Both aircraft achieved a few centimetres of accuracy, despite the greater positional accuracy of the Phantom 4 Pro. The errors are compared by coordinate axes with a two-way analysis of the variance ANOVA , where statistically significant differences are found between remotely piloted aircraft. These are shown in plane and altitude accuracy, where the Phantom 4 Pro proves to be a more accurate alternative.
