Three-dimensional analysis of the aurora is significant because the shape of aurora depends on solar wind which influences electric equipment such as satellites. Our research group set two fish-eye cameras in Alaska, U.S.A and reconstructed the Aurora's shape from a pair of stereo images [Fujii <i>et al</i>. 2014]. However, the method using the(More)
Three-dimensional analysis of the aurora which is an atmospheric phenomenon is significant because the shape of aurora reflects the electromagnetic relationship between the Earth and the Sun, which can influence electric equipments such as satellites. To analyze a number of auroras, our research group set two fish-eye cameras in Poker Flat Research Range(More)
—Three-dimensional measurement of aurora, including its altitude is so difficult that it has not been done before. In this paper, we propose to observe aurora using a fish-eye stereo camera system which can acquire a panoramic view of the sky in a single shot. Stereo observation needs the information of posture of each camera constructing a stereo system.(More)
Auroral microphysics still remains partly unexplored. Cutting-edge ground-based optical observations using scientific complementary metal-oxide semiconductor (sCMOS) cameras recently enabled us to observe the fine-scale morphology of bright aurora at magnetic zenith for a variety of rapidly varying features for long uninterrupted periods. We report two(More)
In this paper, we proposed a novel method to measure and visualize 3D shape of aurora accurately. The proposed method considers not only information of aurora images taken by stereo camera system but also constraints based on the mechanism and physical knowledge of aurora generation. The corresponding points between a pair of stereo images were detected for(More)
