Abstract

V delu opisujemo potek modeliranja kapele samostana Jurklošter na osnovi laserskega oblaka točk. Opisali smo postopek pridobitve podatkov, začetno obdelavo (registracija in georeferenciranje) in pripravo za uvoz v AutoCAD z vtičnikom UNDET. Predstavili smo postopek modeliranja z vključeno razlago modeliranja detajlov (okno v gotskem slogu, obokan strop) in možnih problemov skupaj s podanimi rešitvami. Raziskali smo možnost vključevanja trikotniških mrež v 3D model in ocenili primernost vtičnikove vgrajene funkcije za grajenje trikotniških mrež. Modeliranje je bilo uspešno izvedeno v celoti; zajeli smo vse pomembne detajle objekta in v model uspešno integrirali trikotniške mreže. Vzpostavili smo delovni proces za integracijo mrežnih ploskovnih modelov v programa AutoCAD in SketchUp. Primerjali smo prednosti in slabosti oblakov točk, pridobljenih s terestričnim laserskim skenerjem Leica BLK360 in tahimetrom Leica MS50. Ugotovili smo, da je 3D modeliranje v izbrani programski rešitvi precej zamudno in težko za učenje, v kolikor uporabnik nima predhodnih izkušenj s 3D modeliranjem v okolju AutoCAD.

Secondary title: ǂThe ǂ3D modeling of Jurklošter charterhouse chapel from terrestrial laser scanning point cloud
Secondary abstract: This thesis describes a workflow for point cloud 3D modeling of a chapel in Jurklošter charterhouse. Data acquisition, along with preliminary processing is described (point cloud registration and georeferencing), as well as data preparation for import to AutoCAD with installed UNDET plugin. Modeling workflow is presented, focusing on detailed explanation of complex details modeling, such as gothic window and vaulted ceiling. An option of creating and implementing meshes is explored. Modeling of the chapel has been successfully performed, as the model contains all important features and successful mesh integration. A workflow for integrating mesh surface model into the AutoCAS and SketchUp programs has been developed. Advantages and disadvantages of point clouds, acquired with Leica BLK360 and Leica MS50, have been analysed. 3D modeling from point cloud with chosen software has proved to be time consuming and hard to learn, especially if a person who is working on these tasks has no previous experience with 3D modeling in AutoCAD software.
