In this paper, we propose a method to achieve positions and poses of multiple cameras and temporal synchronization among them by using blinking calibration patterns. In the proposed method, calibration patterns are shown on tablet PCs or monitors, and are observed by multiple cameras. By observing several frames from the cameras, we can obtain the camera positions, poses and frame correspondences among cameras. The proposed calibration patterns are based on pseudo random volumes (PRV), a 3D extension of pseudo random sequences. Using PRV, we can achieve the proposed method. We believe our method is useful not only for multiple camera systems but also for AR applications for multiple users.
