20.500.12556/RUL-165853 Determination of chimney non-verticality from TLS data using RANSAC method The continuous monitoring of tall industrial buildings is necessary to ensure safe operation. Withtechnological advances interrestrial laser scanning and other non-contact measurement methods, the methods and techniques for assessing the stability of tall industrial chimneys are evolving. This paper presents a method for determining the non-verticality and straightness of chimneys that offers significant advantages over existing methods. Narrow bands of scanned point clouds are processed at selected height intervals. Using the RANSAC method, points that do not belong to the chimney shell are filtered and the centre of the circle or ellipse is adjusted using the least squares method. The proposed method enables the efficient filtering of point clouds due to frequent obstructions on the chimney shell, the determination of the regularity of the chimney shell shape, a mathematical analysis of the chimney axis curvature, and an intuitive graphical representation of chimney non-verticality. The comparison of the results with other studies confirms the efficiency of the method. chimney terrestrial laser scanning non-verticality RANSAC least squares method deformations dimnik terestrično lasersko skeniranje nevertikalnost RANSAC metoda najmanjših kvadratov deformacije true false true Angleški jezik Slovenski jezik Članek v reviji 2024-12-12 12:12:03 2024-12-12 12:12:08 2024-12-13 03:57:45 0000-00-00 00:00:00 2024 0 0 19 str. iss. 23, art. 16234541 Vol. 16 2024 0000-00-00 PostprintKoncna Objavljeno NiDoloceno 0000-00-00 0000-00-00 2024-12-04 528.7:624 2072-4292 10.3390/rs16234541 218414339 remotesensing-16-04541_(1)_(1).pdf remotesensing-16-04541_(1)_(1).pdf 1 EB761A90589F3D3AD1E63CEA344D50E5 a5a1821da47deedebefedfd53ff54e04e254fa46d30796d0af815addacde747f 8cfd39bc-b879-11ef-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=197114 https://www.mdpi.com/2072-4292/16/23/4541 1 6d8b6996-b879-11ef-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=197113 Fakulteta za gradbeništvo in geodezijo 0 0 0
