Abstract

Skija se prvo postavlja na držače skije koji su montirani na donji dio konstrukcije stroja, nakon toga se cijela skija slika nizom slika. Svaka od niza slika se obrađuje naprednom metodom obrade slike dok se sve ogrebotine ne izluče od ostatka skije. Pomoću pronađenih ogrebotina na slici se računaju mjesta na koja je potrebno kapnuti plastiku kako bi se te ogrebotine pokrile. Uređaj koji kapa plastiku se dovodi u početni položaj te se nakon toga pozicionira na jedno po jedno mjesto dok ne popuni sve ogrebotine. Na kraju se opet vraća na početak kako bi se stroj mogao ponovo pokrenuti.

Abstract (english)

The ski is first placed on the ski holders mounted on the lower part of the machine construction, after which the whole ski is photographed in a series of images. Each of the images is processed with an advanced image processing method until all the scratches are segmented. With scratches found in the image, the places are determined where the melt plastics drops need to be deployed to cover those scratches. The melt plastics holder is brought to its initial position and then positioned in all detected places until all the scratches are filled. In the end, the machine is guided back to the start so that it can be restarted again.
