HARMONIC OSCILLATIONS MODELLING FOR THE PURPOSE OF CAMERA SYNCHRONIZATION
The goal of this paper to present a general method to synchronize cameras from the image modelled harmonic oscillations, which are in this work produced by a simple pendulum. The method essence is to recover from camera images a sine trajectory of a small ball, attached to 45cm string and suspended from a pivot so that it can swing freely. From this trajectory and given an equilibrium position of ball in space, for each camera a time is estimated needed to reach this equilibrium position from a neighboring frame during a ball swing. The difference in those times for two cameras yields a subframe time difference between cameras. The subframe time differences between cameras were computed using the proposed method and they were compared against the ground truth measurement values given by a camera manufacturer. Linear correlation coefficient is 0.996, while the mean absolute difference between two methods measurements is 3.5ms.
