This paper describes the preparation of documentation of a part of the cultural and historical heritage of Bosnia and Herzegovina, the famous chapel on the Orthodox cemetery ‘Holy Archangels George and Gabriel’ located in Sarajevo, by the method of UAV photogrammetry. Two aircrafts (semi-professional and amateur) DJI Phantom 4 Pro and DJI Mavic Pro were used, and 3D models were made based on the photos taken. The quality of chapel 3D models was evaluated by estimating the geometrical accuracy, with different aspects and combinations. The obtained absolute 3D accuracy of the high-resolution model is 14 mm, while the relative accuracy is 9 mm.

• Title: Ocena kakovosti 3D modela spomenika kulturnozgodovinske dediščine izdelanih na osnovi snemanja z različnimi nizkocenovnimi brezpilotnimi letalniki

Abstract

Delo opisuje pripravo dokumentacije dela kilturno zgodovinske dediščine Bosne in Hercegovine, to je znane kapele na pravoslavnem pokopališču "Sveti arhanđeli Georgije in Gavrilo" v Sarajevu z metodo UAV fotogrametrije. Uporablena sta bila dva letalnika (polprofesionalni in amaterski) DJI Phantom 4 Pro in DJI Mavic Pro. Na osnovi pridobljenih fotografij so bili izdelani 3D modeli snemanega objekta. Parametri kakovosti 3D modela kapele so pridobljeni na osnovi ocehne geometrijske točnosti iz različnih aspektov in kombinacij. Dobljena absolutna točnost modela visoke ločljivosti je 14 mm, relativna točnost pa 9 mm.
