We present a camera calibration system that is simple to use and offers generality in the positioning of the cameras. This makes it very suitable for the calibration of mobile, synchronized camera setups. We use a camera graph to perform global registration which helps lifting restrictions on the camera setup imposed by other calibration methods. A further advantage is, that all information is taken into account at the same time. The method is based on a virtual calibration object which is constructed over time. This implies that no calibration object must be visible simultaneously in all cameras. Keywords External Camera Calibration, Registration, Multi-Video System, Graphs
