Abstract
U prvom dijelu rada je predložen automatizirani optički sustav kontrole dimenzija O-prstena. Opisane su mjerene veličine O-prstena, te komponente, kalibracija i postavljanje optičkog sustava. Predstavljena je i programska podrška mjernog sustava, izrađena pomoću programskog jezika Python i programskih paketa otvorenog koda. Prikazan je način korištenja grafičkog sučelja programskog rješenja i pojašnjeni su algoritmi kalibracije, mjerenja i predobrade digitalnih slika. U drugom dijelu rada je prikazan postupak mjerenja O-prstena mikrometarskim vijkom, te pomoću optičkog mjernog sustava. Sposobnost oba sustava je analizirana primjenom Six Sigma metodologije. Ispitana je osjetljivost optičkog mjernog sustava na kvalitetu kalibracije. Automatizirani i ručni mjerni sustav su uspoređeni pomoću statističkih pokazatelja ponovljivosti i obnovljivosti, te intraklasnog koeficijenta korelacije. Na kraju su predložene mjere povećanja kvalitete optičkog mjernog sustava.
Abstract (english)
In the first section of the thesis, an automated visual inspection system for O-ring measurement is proposed. Measured O-ring features are also defined. Optical system components, calibration and setup are described. Measurement system software solution, developed using the Python programming language and the open-source software, is also introduced. Instructions for using software solution graphical interface are composed, and the algorithms for calibration, measurement and digital image preprocessing are defined. The second part of thesis presents methods for measuring the O-ring using micrometer and the optical measurement system. The capability of each system is analyzed using the Six Sigma methodology. Optical measurement system sensitivity to the calibration is examined. Automated and manual measurement systems were compared by means of repeatability and reproducibility and intraclass correlation coefficient. Finally, the measures to increase the quality of the optical measurement system are proposed.
