Summary
| Description |
English: This is from an experiment I made for my thesis in the field of nonlinear elasticity. It is a thin wooden beam fixed on one end. Force is applied trough a rubber band on the other end. The amount of force is determined from its current length and a separate stiffness experiment. The curves were extracted from several pictures using openCV machine vision library and afterwards approximated by parametric 8-degree polynomials in x and y directions. Software was scripted in Python2 and image processing was done in Gimp. Slovenščina: Na sliki je del poskusa, izvedenega v okviru moje magistrske naloge s podrocja nelinearne elastičnosti. Tanek lesen nosilec je na enem koncu konzolno vpet. Na drugem koncu se preko elastike vanj vnaša silo. Velikost slednje je določena iz njene trenutne dolžine uporabljajoč rezultate predhodnjega eksperimenta - določitve togosti. Krivulje iz nabora slik so pridobljene s pomočjo knjižnjice OpenCV za strojni vid ter naknadno aproksimirane s parametričnima polinomoma osme stopnje v smereh x in y. Programi so napisani v jeziku Python, obdelava slik pa izvedena s programom Gimp. |
