Outline of Final Research Achievements

In this study, a methodology for 3D measurement and visualization of aurora were proposed. To analyze auroras, two fish-eye cameras were set in Poker Flat Research Range, Alaska, USA. The feature points were detected from a pair of images captured by fish-eye cameras, the three-dimensional points were triangulated, and 3D aurora shapes were visualized in 3D space.
