Abstract: | We present a method for external camera calibration that is simple to use and o ers 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 simultaneously. The method is based on a virtual calibration object which is constructed over time by tracking an easily identi able object through three-dimensional space. This implies that no calibration object must be visible simultaneously in all cameras. |
