Abstract
Osnovni cilj ovog diplomskog rada bio je obraditi fotografije SfM metodom fotogrametrije prikupljane posljednjih nekoliko godina. Poanta je kroz rad prikazati i objasniti osnovne principe funkcioniranja SfM metode fotogrametrije kao i način funkcioniranja SfM algoritama. Također, u radu je objašnjena kompletna metodologija generiranja 3D oblaka točaka kao i koraci korištenja softverskih paketa Agisoft i CloudCompare. Opisana je oprema koja se koristi prilikom terenskih snimanja te situacije u kojima je snimanja najpoželjnije odrađivati. Ovaj rad daje odgovore na pitanja što je zapravo SfM fotogrametrija, na koji način ju je moguće koristiti te koja je primjena takve metode? Opisano je nekoliko primjera gdje se, za velike projekte, koristi SfM metoda fotogrametrije te koje su njene prednosti u odnosu na klasičnu fotogrametriju. Agisoft kao programski paket služi za generiranje 3D oblaka točaka iz fotografije te kreiranje 3D modela. Detaljno su opisani koraci od upoznavanja sa sučeljem i radnim okruženjem programa pa do generiranja 3D oblaka točaka, digitalnih elevacijskih modela (DEM) i ortomosaic fotografija, tj. orto-foto karata. Također, opisana je i procedura georeferenciranja kreiranih oblaka točaka kao jedan od bitnih faktora kada se radi o usporedbi istih. Istraživanje se odnosi na područje grada Brseča koji se nalazi u Kvarnerskom zaljevu, točnije, na žal Klančac u blizini spomenutog grada. Odabrano je ovo područje istraživanja iz razloga što su posebnost minijaturnih šljunčanih žala izražene morfološke promjene izazvane djelovanjem valova na obalu. Obilježavaju ih značajne oscilacije volumena i rotacije tijela žala, u slučaju kada su izložena djelovanju valova iz različitog smjera pa su, analogno tome, takva žala izuzetno povoljna za istraživanja. Kao rezultati prikazane su razlike u volumenima tijela žala, razlike u visinama za nekoliko uspoređenih oblaka točaka i razlike u poprečnim presjecima.
Abstract (english)
The main aim of this graduate thesis was to process the photos collected over the last few years with SfM method of photogrammetry. The point is to show and explain the basic principles of the function of the SfM photogrammetry as well as how the SfM algorithms works. In addition, a complete methodology for generating 3D point clouds as well as the steps of using software packages Agisoft and CloudCompare has been explained. The equipment used in field shooting and the situations where the shooting is most desirable is described too. This thesis gives answers to the questions of what SfM photogrammerty actually is, how it can be used and what is the application of such a method? Several examples are described where, for large projects, the SfM photogrammetry is used its advantages over the classical photogrammetry. Agisoft as a software package serves to generate 3D point clouds from photos and creating a 3D models. Detailed steps are taken to familiarize yourself with the interface and work environment of the softwer, and to generate 3D point clouds, digital elevation models (DEMs) and orthomosaic photographs, ie ortho-photo maps. Also, a georeferencing procedure for created point clouds is described as one of the essential factors when comparing it. The survey refers to the area of the town of Brseč, which is located in the Kvarner Bay, more precisely, on the beach of Klančac near the mentioned town. This area of research was selected becouse of the distinct feature of these gravel beaches is that the changes in beach morphology are caused by waves. This is demonstrated by the significant oscillation of beach volumes and beach rotation due to successive waves arriving from different directions, so, similarly, such a beaches are extremely favorable for research. The results show the differences in body volumes of the beach, cross sections, and difference in altitudes for several computed point clouds.
