Abstract

Magistrsko delo "Analiza vpliva prostorske ločljivosti oblakov točk na izračun prostornin" zajema filtriranje oblakov točk bližnjeslikovnega zajema in izračun prostornin deponiranega gradbenega materiala. V delu so predstavljeni fotogrametrični oblaki točk kot izvorni podatki. Opisan je postopek pridobivanja teh oblakov in njihova uporabnost. Opisana so testna območja in uporabljena programska oprema za izvedbo postopkov filtriranja in izračuna prostornin. Predstavljeni so izvedeni postopki izreza testnih območij, filtriranja oblakov točk, interpolacije ploskev ter izračuna prostornin. V zaključku magistrskega dela so predstavljeni in analizirani rezultati. Podane so ugotovitve glede vpliva avtomatskih in ročnih postopkov na izračun prostornin, glede učinkovitosti posamezne programske opreme pri filtriranju oblakov točk in glede vpliva prostorske ločljivosti oblakov točk na izračunano prostornino. Ugotovitve lahko koristijo prihodnjim uporabnikom programske opreme ali fotogrametričnih oblakov točk.

Secondary title:	Impact analysis of the point clouds spatial resolution on the calculated volumes
Secondary abstract:	The Master thesis covers point clouds filtering for close-range capture and calculations of the volume of deposited building material. The paper presents photogrammetric point clouds as data sources. Moreover, it describes the method of obtaining these clouds and their applicability. The test area and software used for implementation of filtering and calculation of volumes are defined in the paper. Carried out operations of clipped test areas, filtering point clouds, interpolations of the surface and calculations of volumes are described. Results of the research are identified and analysed. Conclusions on the impact of automated and manual procedures to calculate volumes are given in the paper, together with conclusions on the effectiveness of individual software for filtering of point clouds, as well as conclusions on the impact of spatial resolution point clouds on the calculated volume. Those conclusions may be useful for future software or photogrammetric point clouds users.
