Abstract:3D rekonstrukcija je več koračni postopek gradnje globinskih modelov iz 2D slik. V diplomskem delu smo predstavili postopek pridobivanja globinskih modelov iz zaporedja več slik. Podrobno smo analizirali fazo projekcijske rekonstrukcije, ki je ena izmed ključnih faz za natančno 3D rekonstrukcijo točk v prostoru. Preučili smo različne metode za izračun projekcijske matrike, in sicer faktorizacijsko metodo, metodo s temeljno matriko in metodo s kalibracijskimi podatki. Predstavili smo sistem, kjer smo omenjene metode implementirali in jih glede na izpeljan evalvacijski kriterij primerjali. Rezultati so pokazali, da je metoda s temeljno matriko najuspešnejša.

Title:COMPARISON OF 3D-RECONSTRUCTION METHODS
Abstract:3D-reconstruction is a multi-step method for constructing depth (3D) models from 2D images. In our diploma work, we presented a procedure for acquiring 3D models from a sequence of multiple images. We analyzed in detail a phase for projection reconstruction, which is one of the key steps for accurate 3D-reconstruction of points in space. We studied different methods for projection matrix calculation, namely the factorization method, method with fundamental matrix, and method with calibration data. We presented a system where these methods were implemented and compared according to an evaluation criterion. Results pointed out that the method with fundamental matrix is the most successful.
Keywords:3D-reconstruction, computer vision, fundamental matrix, calibration, multiple view geometry, corresponding points
