TubeMap: A Projection for Omnidirectional View Interpolation
Naoki Kawai, Takao Kondo, Mina Tanaka · 2020
We propose a projection for omnidirectional images called TubeMap which is efficient for omnidirectional view interpolation. This new projection keeps linearity on the captured scenes and covers almost every direction in a single region with no discontinuities by extending the projection planes of a cube map along the direction from one camera towards another. TubeMap makes it easy to construct correspondence between two omnidirectional images while eliminating distortion on interpolated views.
