20.500.12556/RUL-128430 New target for accurate terrestrial laser scanning and unmanned aerial vehicle point cloud registration The main goal of our research was to design and implement an innovative target that would be suitable for accurately registering point clouds produced from unmanned aerial vehicle (UAV) images and terrestrial laser scans. Our new target is composed of three perpendicular planes that combine the properties of plane and volume targets. The new target enables the precise determination of reference target points in aerial and terrestrial point clouds. Different types of commonly used plane and volume targets as well as the new target were placed in an established test area in order to evaluate their performance. The targets were scanned from multiple scanner stations and surveyed with an unmanned aerial vehicle DJI Phantom 4 PRO at three different altitudes (20, 40, and 75 m). The reference data were measured with a Leica Nova MS50 MultiStation. Several registrations were performed, each time with a different target. The quality of these registrations was assessed on the check points. The results showed that the new target yielded the best results in all cases, which confirmed our initial expectations. The proposed new target is innovative and not difficult to create and use. artificial target terrestrial laser scanning SfM photogrammetry registration registration quality umetna tarča terestrično lasersko skeniranje SfM-fotogrametrija registracija kakovost registracije true false true Angleški jezik Slovenski jezik Članek v reviji 2021-07-13 14:11:29 2021-07-13 14:11:35 2022-09-07 04:15:08 0000-00-00 00:00:00 2019 0 0 29 str. iss. 14, art. 3179 Vol. 19 2019 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 528(045) 1424-8220 10.3390/s19143179 8860513 RAZ_Urbancic_Tilen_2019.pdf RAZ_Urbancic_Tilen_2019.pdf 1 5D61520E18A4CFE936E0A2EB38338AC6 4d5cbd089f68dbc2ef029bc4709ec934749f347c7c0d97c0203c5e1c1330a614 924718a9-e3d3-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=145170 https://www.mdpi.com/1424-8220/19/14/3179 1 533d9156-e3d3-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=145169 Fakulteta za gradbeništvo in geodezijo 0 0 0
