20.500.12556/RUL-160891 Flat specimen shape recognition based on full-field optical measurements and registration using mapping error minimization method Prepoznava oblike planih preizkušancev z uporabo optičnih metod merjenja celotnih polj deformacij in poravnava oblike z uporabo minimizacije odstopanja preslikave In the paper, an alignment methodology of finite element and full-field measurement data of planar specimens is presented. The alignment procedure represents an essential part of modern material response characterisation using heterogeneous strain-field specimens. The methodology addresses both the specimen recognition from a measurement`s image and the alignment procedure and is designed to be applied on a single measurement system. This is essential for its practical application because both processes, shape recognition and alignment, must be performed only after the specimen is fully prepared for the digital image correlation (DIC) measurements (white background and black speckles) and placed into a testing machine. The specimen can be observed with a single camera or with a multicamera system. The robustness of the alignment method is presented on a treatment of a specimen with a metamaterial-like structure and compared with the well-known iterative closest point (ICP) algorithm. The performance of the methodology is also demonstrated on a real DIC application. full-field measurements digital image correlation specimen shape recognition surface registration iterative closest point meritve polja deformacij korelacija digitalnih slik prepoznava oblike preizkušanca poravnava oblik inverzna identifikacija heterogeno polje deformacij true false true Angleški jezik Slovenski jezik Članek v reviji 2024-09-05 09:33:56 2024-09-05 09:33:58 2025-08-08 13:33:30 0000-00-00 00:00:00 2021 0 0 Str. 203-213, SI 29 no. 5 Vol. 67 May 2021 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 539.37:004.932(045) 0039-2480 10.5545/sv-jme.2021.7111 65014787 Macek,_Urevc,_Halilovic_-_Flat_Specimen_Shape_Recognition_Based_on_Full-Field__Optical_Measurements_and_Registration_Using__Mapping_Error_Minimization_Method.pdf Macek,_Urevc,_Halilovic_-_Flat_Specimen_Shape_Recognition_Based_on_Full-Field__Optical_Measurements_and_Registration_Using__Mapping_Error_Minimization_Method.pdf 1 EDF9A43232B43AAF1610C1ECEC030B07 b56a6a754729be49200442d96e38a88c60b90a0d9b4ee00084739e1773c2992f 99680184-6b59-11ef-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=189698 https://www.sv-jme.eu/sl/article/alignment-of-modelling-and-full-field-measurement-data-for-material-characterisation-of-planar-specimens/ 1 37505dba-6b59-11ef-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=189697 Fakulteta za strojništvo Strojniški vestnik 0 0 0
