Abstract

Klifovi u mekim stijenama vrlo su dinamičan okoliš koji se neprestano erodira i mijenja
te je zbog sve većeg iskorištavanja u turističke i graditeljske svrhe važno pratiti eroziju klifova
i uočiti moguće zone hazarda. S razvitkom tehnologije pojavile su se nove metode u izradi
modela pri čemu se olakšavaju brojne analize klifova, a jedna od njih izrada je 3D modela
metodom digitalne fotogrametrije. Metodom SfM-MVS fotogrametrije moguće je stvoriti
digitalne modele reljefa klifa te utvrditi geomorfološke promjene na njima.
U ovom radu prikazana je izrada 3D modela klifa na Duilovu koji je nastao u mekim
stijenama, konkretnije u flišu. Predstavljeni su najbitniji koraci za izradu takve vrste modela te
su objašnjeni najčešći problemi koji se mogu pojaviti pri izradi. Završni rezultat modeliranja
klifa na Duilovu u ovom seminarskom radu je digitalni površinski model (DSM).

Abstract (english)

Cliffs developed in soft rocks are a very dynamic environment that is constantly eroding
and changing. Due to the increased use of cliffs for tourist and construction purposes, it is
important to monitor erosional processes of cliffs and identify possible hazard zones. The rapid
development of technology resulted in the emergence of new methods for modeling purposes,
facilitating thus a various analysis of cliff processes. One of them is creating 3D models by
digital photogrammetry. Using the SfM-MVS photogrammetry, it is possible to create digital
models of cliffs and determine geomorphological changes in them.
This paper is presenting the creation of a 3D model of a cliff in Duilovo which was made
in soft rocks, more specifically in flysch. The most important steps for creating this type of
model are presented, and the most common problems that may appear during the process are
explained. The final result of cliff modeling in this paper is the digital surface model (DSM).
