Abstract

Ovim diplomskim radom istraživana je mogućnost korištenja bespilotne letjelice DJI Mavic 3 Enterprise opremljene kamerom DJI Mavic 3E Wide pri izmjeri normalnih poprečnih profila šumske ceste nizinskog reljefnog područja koja se provodila u UŠP Bjelovar, šumariji Vrbovec, gospodarskoj jedinici „Česma“ u usporedbi sa referentnom metodom terenske izmjere koju je predstavljala upotreba totalne stanice. Ujedno se testirao utjecaj dubine stagnirajuće vode u odvodnim jarcima te visine vegetacije sa pokosa nasipa na točnost očitanih podataka sa digitalnih modela terena (zimski i proljetni aspekt) dobivenih temeljem aerofotografija prikupljenih bespilotnom letjelicom, odnosno analizirano je dolazi li do statistički značajne razlike u očitanim x, y, i z koordinatama točaka (validacijskih i terenskih) sa DMR-ova u odnosu na prikupljene x, y, i z koordinate točaka (validacijskih i terenskih) referentnom metodom terenske izmjere uz utvrđivanje uzroka pogreške. Rezultati rada doprinijet će boljem razumijevanju mogućnosti korištenja bespilotnih letjelica pri provođenju ovakve vrste terenskih istraživanja a definiranje uzroka zamijećenih razlika u očitanim/prikupljenim podacima zasigurno će biti od pomoći pri odabiru prikladne metode terenske izmjere poprečnih profila šumskih cesta nizinskoga reljefnog područja.

Abstract (english)

The purpose of the thesis was to investigate the possibility of using the DJI Mavic 3 Enterprise unmanned aerial vehicle equipped with the DJI Mavic 3E Wide camera in forest road normal cross section profile survey in the lowland forest area. The research was conducted in the UŠP Bjelovar, forestry office Vrbovec, management unit "Česma". UAV data was compared to the field survey reference method, recorded by total station. At the same time, stagnant water depth in the ditches and the vegetation height on the embankment slope influence on the (accuracy) precision of the digital terrain models (winter and spring aspect) generated on the basis of aerial photographs collected by an unmanned aerial vehicle was tested, that is, analyzed whether there is a statistically significant difference in the x, y, and z coordinates of points (validation and field) from DTMs in relation to the recorded x, y, and z coordinates of points (validation and field) using the reference method of field measurement todetermine the cause of the error. The results of the thesis will contribute to a better understanding of the possibilities of using unmanned aerial vehicles for conducting this type of field research, while defining the causes of observed differences in the read/collected data will certainly be helpful for choosing a suitable field measurement method of cross section profiles of forest roads in a lowland area.
