Obdelava oblaka točk, pridobljenega s 3D laserskim skeniranjem, za modeliranje opreme prostora

Hartman, David (author), Kariž, Mirko (mentor)

Namen magistrskega dela je bil proučiti različne programske opreme za obdelavo oblakov točk, pridobljenih s 3D laserskim skeniranjem. Delo je nastalo v okviru dela v podjetja LES CAD d.o.o., ki se ukvarja z načrtovanjem notranje opreme in pri svojem delu uporablja modelirni program TopSolid. Naredili smo pregled naprav za lasersko skeniranje in preizkusili skener Leica RTC360 s skeniranjem pisarne. Za obdelavo oblaka točk smo preizkusili naslednje programe: MeshLab, CloudCompare, Revit, Rhino in AutoCAD. Cilj je bil iz oblaka točk pridobiti datoteko primerno za uvoz v program TopSolid in izdelati natančen 3D model prostora, ki omogoča nadaljnje modeliranje notranje opreme. S pravilno izbiro programske opreme in ustreznega postopka smo uspešno pridobili datoteko za uvoz v program za modeliranje in pripravili model objekta. Ugotovili smo, da se z izbiro ustrezne programske opreme in obdelave zmanjša velikost datoteke ter olajša nadaljnje modeliranje opreme v izbranem prostoru. Čas obdelave se sicer ne zmanjša, se pa s skeniranjem občutno zmanjša čas meritev na objektu. Za podjetje LES CAD d.o.o., ki se ukvarja z načrtovanjem notranje opreme, je najprimernejša obdelava oblaka točk v programu AutoCAD ter izdelava končnega modela v programu TopSolid. S to kombinacijo lahko pridobijo model prostora, ki zagotavlja dovolj visoko natančnost za nadaljnje delo.

• Title: Processing of a point cloud obtained by 3D laser scanning for modelling of interior equipment

Abstract

The aim of this work was to investigate different software for processing point clouds obtained by 3D laser scanning. The work was carried out within the company LES CAD d.o.o., which deals with interior design and uses the TopSolid modelling program for its work. During the research we obtained an overview of laser scanning devices and tested the Leica RTC360 scanner by scanning an office. We tested the following point cloud processing programs: MeshLab, CloudCompare, Revit, Rhino and AutoCAD. The goal was to obtain from the point cloud a file suitable for importing into TopSolid and to create an accurate 3D model of the room, which would allow further modelling of the interior in the selected room. With the right choice of software and the appropriate approach, we managed to obtain a file for importing into the modelling program and create a model of the room. We found that choosing the right software and procedure reduces the file size and facilitates further modelling of the furnishings in the selected room. The processing time is not reduced, but the time needed to measure the objects is significantly shorter when scanning is used. For LES CAD d.o.o., which deals with interior design, processing the point cloud in AutoCAD and creating the final model in TopSolid is the most suitable approach. In this way, a model of the space is obtained that provides sufficient accuracy for further work.
