Abstract

This contribution deals with the possibility of using high-speed digital image correlation system in motion analysis. In the first part the principle and methodology of high-speed measurements is briefly introduced. The paper also describes the analysis by which the minimal sampling frequency of cameras necessary for registration of increasing velocity of the investigated object was determined. In the second part of the contribution the motion of a simple pendulum is described analytically. In the third part the experimental motion analysis of a simple pendulum was performed using high-speed digital image correlation system Q-450 Dantec Dynamics, by which its behavior was investigated and finally, the obtained results were verified using numerical simulation in Matlab/Simulink.
