Abstract

U ovom radu daje se definicija dubinske mape i objašnjava se koja je njezina uloga u stvaranju 3D slika. Opisuju se načini stvaranja dubinske mape. Automatko generiranje dubinske mape objašnjeno je na primjeru programa DMAG (Depth map automatic generator) koji se temelji na stereo podudaranju varijacijskih metoda u kontekstu optičkog toka stereo para slika. Samostalna izrada dubinske mape objašnjena je korištenjem programa GIMP (GNU image manipulation program). Kao referentna slika za izradu 3D slika koristila se lijeva slika stereo para slika koja prikazuje bicikle. 3D slike se stvaraju pomoću programa Bas-relief Demo i uspoređuju se rezultati za različite dubinske mape. Rezultati se također uspoređuju s 3D slikom dobivenom direktno iz stereo para slika bicikala.

Abstract (english)

This paper gives a definition of a depth map and explains what its role is in creating 3D images. It is described how a depth map can be created. The automatic generation of a depth map is explained on the example of the DMAG (Depth map automatic generator) program, which is based on stereo matching of variation methods in the context of the optical flow of stereo pair images. Manual creation of the depth map is explained using the GIMP (GNU image manipulation program). The left image of a stereo pair images, which shows bicycles, is used as a reference image for creating 3D images. 3D images are created using the Bas-relief Demo program and the results for different depth maps are compared. The results are also compared with a 3D image obtained directly from stereo pair of bicycle images.
