In this paper we present new constraints for calibration of underwater stereo-camera-systems and 3D-reconstruction. These constraints are both intuitive and simple to realize. We show that additionally needed refractive parameters in such a system can be calibrated simultaneously. Our constraints partially build upon each other. A subset of them even enables the calibration from stereo-correspondences alone, making known calibration targets unnecessary.
