Calibration of multi-Kinect and multi-camera setup for full 3D reconstruction

In this paper, a new calibration method is presented for multi-Kinect and multi-camera setup. This method is developed by considering that the depth measurement principle of the Kinect is triangulation. The depth values obtained from the Kinect are sometimes inaccurate because the manufacturer´s calibration between IR projector and IR camera becomes invalid by the tolerances in manufacturing, temperature variation and vibration during transportation. To improve the results from the previous calibration methods, an analytic approach is presented. Experiments show that the induced depth correction model is reasonable and the results from the proposed approach are better than those of the previous approaches.
