Equatorial stitching of hemispherical images in a spherical image capture system
First Claim
1. A camera apparatus configured to stitch hyper-hemispherical images, the camera apparatus, comprising:
- a first camera that faces a first direction, the first camera configured to capture a first circular image corresponding to a first hyper-hemispherical field of view;
a second camera that faces a second direction, the second camera configured to capture a second circular image corresponding a second hyper-hemispherical field of view;
a processing apparatus; and
a non-transitory computer-readable apparatus comprising a storage medium having instructions for stitching the first and the second hyper-hemispherical fields of view to generate a rectangular projection of a spherical image, the instructions when executed by the processing apparatus, cause the processing apparatus to;
receive the first circular image corresponding to the first hyper-hemispherical field of view captured by the first camera facing the first direction and the second circular image corresponding to the second hyper-hemispherical field of view captured by the second camera facing the second direction;
project the first circular image to a first rectangular image via a map of an outer edge of the first circular image to a bottom edge of the first rectangular image and a map of a center point of the first circular image to a top edge of the first rectangular image;
project the second circular image to a second rectangular image via a map of an outer edge of the second circular image to a top edge of the second rectangular image and a map of a center point of the second circular image to a bottom edge of the second rectangular image; and
stitch the bottom edge of the first rectangular image with the top edge of the second rectangular image to generate the rectangular projection of the spherical image.

Abstract
Hyper-hemispherical images may be combined to generate a rectangular projection of a spherical image having an equatorial stitch line along of a line of lowest distortion in the two images. First and second circular images are received representing respective hyper-hemispherical fields of view. A video processing device may project each circular image to a respective rectangular image by mapping an outer edge of the circular image to a first edge of the rectangular image and mapping a center point of the circular image to a second edge of the first rectangular image. The rectangular images may be stitched together along the edges corresponding to the outer edge of the original circular image.
