Determining the kinematic parameters of moving test objects via the results of video recording

Resumo

Algorithms for processing results of high-speed video recording of the processes of interaction between test objects and barriers are presented. The algorithms make it possible to determine the position of the test object relative to a barrier, as well as the kinematic parameters (the velocity and acceleration) of the points of the test object before, during, and after interaction with the barrier at initial test object collision velocities of up to 120 m/s. The efficiency of the developed algorithms is confirmed by the good coincidence of the results of videogram processing with the results of acceleration measurements by piezoelectric accelerometers.
