Abstract
V diplomski nalogi ugotavljamo spremembe na površju preko izračuna prostornine med dvema ploskvama. To smo naredili na primeru melišča na Potoški planini, za katerega smo imeli na voljo oblaka točk skenirana z enoletnim zamikom. Ob tem nas je zanimala razlika pri izračunu prostornin brez in z uporabno postopka ploskovnega ujemanja, ki transformira oblak točk tako, da so razdalje med točkami v obravnavanih oblakih čim manjše. Izračune prostornin smo tako naredili z in brez uporabe ploskovnega ujemanja v državnem D96 koordinatnem sistemu in v lokalnem koordinatnem sistemu. Iz dobljenih rezultatov ne morem trditi, da je postopek ploskovnega ujemanja na našem primeru imel vpliv na izračunano prostornino, ob samem izrisu sprememb prostornin na terenu pa je vpliv opazen.

Title:
Using surface matching for assesment of surface changes on a scree
Abstract:
This graduation thesis's main goal is to assess surface changes, which is done with computing of volume between two surfaces. It was done on a practical example of a scree on Potoška planina, for which we had two sets of observations made with one year in between. Simultaneously we wanted to determine the difference in computed volume with and without using the process of surface matching, which transforms a point cloud so that the distances between point clouds are minimal. Calculation of volume was done in national D96 coordinate system and in a local coordinate system. After analyzing the results, it is difficult to claim, that surface matching had any influence on computed volume, but graphical representation of results shows a different picture.
