  We propose an easy-to-use non-overlapping camera calibration method. First,
successive images are fed to a PoseNet-based network to obtain ego-motion of
cameras between frames. Next, the pose between cameras are estimated. Instead
of using a batch method, we propose an on-line method of the inter-camera pose
estimation. Furthermore, we implement the entire procedure on a computation
graph. Experiments with simulations and the KITTI dataset show the proposed
method to be effective in simulation.
