US 2018/0025467 A1 · MAPPING OF SPHERICAL IMAGE DATA INTO RECTANGULAR FACES FOR TRANSPORT AND DECODING ACROSS NETWORKS

Abstract

A system receives an encoded image representative of the 2D projection of a cubic image, the encoded image generated from two overlapping hemispherical images separated along a longitudinal plane of a sphere. The system decodes the encoded image to produce a decoded 2D projection of the cubic image, and perform a stitching operation to portions of the decoded 2D projection representative of overlapping portions of the hemispherical images to produce stitched overlapping portions. The system combine the stitched overlapping portions with portions of the decoded 2D projection representative of the non-overlapping portions of the hemispherical images to produce a stitched 2D projection of the cubic image, and encode the stitched 2D projection of the cubic image to produce an encoded cubic projection of the stitched hemispherical images.

A method for stitching overlapping portions of a 2D projection of a cubic representation of a spherical field of view (FOV) comprising:

receiving an encoded image representative of the 2D projection of a cubic image, the encoded image generated from two overlapping hemispherical images separated along a longitudinal plane of a sphere;
decoding the encoded image to produce a decoded 2D projection of the cubic image;
performing a stitching operation to portions of the decoded 2D projection representative of overlapping portions of the hemispherical images to produce stitched overlapping portions;
combining the stitched overlapping portions with portions of the decoded 2D projection representative of the non-overlapping portions of the hemispherical images to produce a stitched 2D projection of the cubic image;
and
encoding the stitched 2D projection of the cubic image to produce an encoded cubic projection of the stitched hemispherical images.
