無人飛行船に搭載された2台の全方位カメラを用いた不可視領域のない全天球HDRビデオの生成(<特集>実世界イメージング)

抄録

This paper describes a method for acquiring full spherical videos without missing areas using a pair of omnidirectional cameras mounted on the top and bottom of an unmanned airship. Omnidirectional videos are captured as multi-exposure images with various shutter speeds to realize high dynamic range (HDR) imaging. The generated videos are intended to be used for telepresence, augmented telepresence, and image-based lighting. In experiments, full spherical HDR videos are generated from image sequences captured from the sky of our campus.
