The use of multi-camera systems in target tracking applications demands to know positions and orientations of each one of the cameras in a global coordinate system. In this work is described the development and implementation of an extrinsic calibration method for multi-camera systems. A theoretical analysis of each stage of the process is shown, pointing out methods and tools. Furthermore, a new calibration pattern is proposed. The validation is performed with simple experiments and in a real deployment of IP cameras.
