Abstract:Cilj diplomskega dela je rekonstruirati 3D model objekta (v našem primeru cerkve) s pomočjo točk, pridobljenih z laserskim prebirnikom LiDAR (ang. Light Detection and Ranging). V prvem delu diplomske naloge predstavimo tehnologijo LiDAR ter opišemo datotečni format LAS, ki predstavlja standardni zapis podatkov LiDAR. V drugem podamo več tehnik geometrijskega modeliranja, pri čemer podrobneje predstavimo najpogosteje uporabljene gradnike in funkcijonalnosti. V tem delu se osredotočimo na programsko okolje Cinema 4D, ki smo ga uporabili za izdelavo našega modela. Podamo tudi krajši opis jezika VRML (ang. Virtual Reality Modelling Language), ki omogoča ustrezno predstavitev končnega modela na svetovnem spletu. Pred zaključnim delom povzamemo najpomembnejše ugotovitve pri izdelavi diplomskega dela in končni model vizualno predstavimo. V zaključnem delu uporabljeni postopek za izdelavo 3D modela še kritično ocenimo in predstavimo tako pozitivne kot tudi negativne lastnosti uporabe takšne metode.

Title:OBJECT RECONSTRUCTION FROM LiDAR POINTS
Abstract:The aim of this diploma thesis is to construct a 3D model of a geometric object (in our case a church) using points gathered by a laser scanner LiDAR. The first part of the thesis deals with LiDAR technology, which is breifly considered. The second part describes basic geometric modelling techniques, focusing on the most frequently used functions. This part includes Cinema 4D graphic package, which was used to create our model. A short description of VRML modelling language follows, which enables representation of created model on the internet. The most important findings of this thesis are summarized before the last part. In the conclusion we evaluate the procedure of making 3D model using LiDAR data points.
Keywords:LiDAR, 3D scanning, geometric modelling, Cinema 4D, VRML
