Abstract
Kut sipanja predstavlja kut koji tvori materijal sa horizontalnom ravninom kada ga se sipa na gomilu. Ovdje je riječ o fizikalnom svojstvu osobito primjenjivom u tehničkim strukama, ali i šire. Naglasak je stavljen na pripremu i izvođenje laboratorijskih ispitivanja koja su za cilj imala utvrditi utjecaj promjene broja fotografija te položaja kamere na iznos kuta sipanja. Navedena ispitivanja vršena su metodom cilindra na realnoj hrpi materijala, a potom i na referentnom stošcu. Obzirom da je korištena metoda 3D modela za određivanje kuta sipanja, obrada digitalnih fotografija rađena je u Agisoft PhotoScan-u, a proračun kuta sipanja u Python-u. Rezultat ispitivanja pokazuje minimalan utjecaj promjene položaja kamere, dok je nešto veći utjecaj prisutan kod promjene broja fotografija na kut sipanja.
Abstract (english)
The angle of repose is the angle that forms the material with the horizontal plane when it is poured on the pile. This is a physical property particularly applicable in the technical professions, but also beyond. Emphasis was placed on the preparation and performance of laboratory tests aimed at determining the impact of changes in the number of photographs and the position of the camera on value of angle of repose. These tests were performed by the cylinder method on a real pile of material and then on a reference cone. Since the 3D model method was used to determine the angle of repose, the processing of digital photos was done in Agisoft PhotoScan and the calculation of the angle of repose in Python. The test result shows a minimal impact of changing the camera position, while a slightly greater impact is present when changing the number of photos on the angle of repose.
