Abstract

Rekonstrukcija prostora iz niza slika problem je u računalnom vidu koji se bavi obnavljanjem trodimenzionalne (3D) strukture iz statične scene reprezentirane nizom dvodimenzionalnih (2D) slika. Metoda kojom se problem rješava je procjena gibanja kamere koja je snimila slike. Ona započinje ekstrakcijom značajki iz slika nakon čega se radi traženje podudaranja tih značajki na više slika. Zatim se radi procjena gibanja kamere pomoću podudaranja značajki. Minimizacijom reprojekcijske pogreške prilikom procjene gibanja i značajki dobiva se 3D struktura. Ovaj rad prezentira metodu rekonstrukcije strukture iz niza slika implementiranu pomoću MATLAB biblioteka i prikazuje njezinu funkcionalnost na prikupljenom nizu slika odabrane strukture.

Abstract (english)

Structure from motion is a problem in computer vision which tackles the reconstruction of a three-dimensional (3D) structure from a static scene represented by a series of two-dimensional (2D) images. The method used to solve the problem is to estimate the motion of the camera that captured the images. It starts with extracting the features from images, after which the extracted features are used for feature matching on multiple images. The camera motion estimation is done using feature matching. By minimizing the reprojection error when estimating motion and features, the 3D structure is obtained. This thesis presents a structure from motion method implemented using MATLAB libaries and displays its functionality on a collected series of images of a selected structure.
