In its theoretical part the basic principle of digital image correlation and description of modification of correlation system Q-450 Dantec Dynamics for the purposes of SIMO (Single Input / Multiple Output) assumption of modal parameters is introduced. The practical part - analysis of reliability of program Modan3D, developed for modal parameters estimation - was realized on a simple steel specimen in laboratory conditions. The obtained outputs are present in a form of graphs and tables.
