Abstract
Cilj magistrskega dela je bil razvoj sistema za 3-dimenzionalno rekonstrukcijo predmetov iz slik. Osredotočili smo se na pasivne metode računalniškega vida in izbrali metodi Stereo vid ter Prostorsko klesanje. Pri uporabi obeh metod morajo biti poznane lege kamere iz katerih so bile slike zajete. Za določitev lege kamere smo uporabili informacijo pridobljeno z detekcijo referenčnega objekta - lista formata A4. Razvili smo sistem, ki uporabnika vodi pri zajemanju slik s pametno mobilno napravo osnovano na platformi Android, nato pa iz zajetih slik zgradi 3D model predmeta v procesnem delu implementiranem v razvojnem okolju Matlab. Tako dobljene 3D modele smo primerjali z referenčnimi, pri čemer smo predlagali ter razvili evalvacijsko metodologijo in napake podrobno preučili ter rezultate ovrednotili. Predstavili smo tudi kvalitativne rezultate na katerih smo izpostavili prednosti in omejitve izbranih metod.

Title:Development of a system for 3D reconstruction of objects using passive computer vision methods
Abstract:
The main goal of the master thesis is to develop a system for reconstruction of 3D objects from colour images. The main focus is on passive computer vision methods from which we select two, i.e., Stereo vision and Space carving. Both methods require information about camera poses. The camera pose for a given image is estimated from the information obtained by detecting a reference object, i.e., a standard A4 paper sheet. We develop an Android based mobile application to guide a user during image capturing process and a Matlab based system for 3D object reconstruction from captured images. The reconstructed 3D models of objects where compared to reference 3D models. Using an evaluation metodology we propose, we evaluated the implemented methods and analysed the results. We also present qualitative results and highlight strengths and shortcomings of the two selected passive computer vision methods for 3D reconstruction.

Keywords:stereo vision, space carving, 3D model, 3D reconstruction, computer science, computer and information science, master's degree
