image completion for ball camera

A ball camera is a high tech ball equipped with cameras to obtain images from the ball’s point of view. To capture 360^◦ images with a minimum number of cameras, we embedded two ultra-wide-angle cameras in the ball. However, the two cameras were set diametri- cally opposite to each other; therefore, a blind spot was present, which could not be captured by the two cameras. Consequently, the obtained 360^◦ image had a discontinuous part. In this paper, we describe the design and implementation of the ball camera and propose a method for completing the blind spot using image com- pletion. We applied our method to the videos captured by the ball camera and proved this method successfully completes the blind spot and provides more real-life images.
