Claim One:
1. A method for mapping spherical images to a 2D projection of a cubic representation of a spherical field of view (FOV) comprising: capturing a first hemispherical image and a second hemispherical image, each of the first hemispherical image and the second hemispherical image including an overlap portion, the overlap portions capturing a same field of view, the first and second hemispherical images collectively comprising a spherical FOV and separated along a longitudinal plane; mapping a modified first hemispherical image to a first portion of the 2D projection of a cubic image, the modified first hemispherical image including a non-overlap portion of the first hemispherical image, wherein the mapping of the modified first hemispherical image to the first portion of the 2D projection comprises: warping the modified first hemispherical image into a first square image; extracting a first central portion from the first square image, the first central portion being a square image; dividing a remainder of the first square image into four remaining portions of the first square image, the four remaining portions of the first square image having equal size; mapping the first central portion to a first face of the 2D projection of the cubic image; and mapping each of the four remaining portions of the first square image to one half of each of a set of four faces of the 2D projection of the cubic image, the set of four faces of the 2D projection of the cubic image including a second, third, fourth, and fifth face of the 2D projection of the cubic image; mapping a modified second hemispherical image to a second portion of the 2D projection of the cubic image, the modified second hemispherical image including a non-overlap portion of the second hemispherical image; mapping the overlap portions of the first hemispherical image and the second hemispherical image to the 2D projection of the cubic image; and encoding the 2D projection of the cubic image to generate an encoded image representative of the spherical FOV.
