Abstract

Systems, methods, and non-transitory computer-readable media can obtain a spherical media content item that captures at least one scene from a plurality of different positions. A three-dimensional shape having a plurality of faces is determined, each face being associated with a respective set of original boundaries. A respective set of expanded boundaries for one or more of the plurality of faces is determined. Respective portions of the spherical media content item are mapped to each of the one or more faces, wherein a first portion of the spherical media content item is mapped to a first face having a set of expanded boundaries.

First claim

What is claimed is:

1. A computer-implemented method comprising:
obtaining, by a computing system, a spherical media content item that captures at least one scene from a plurality of different positions;
determining, by the computing system, a three-dimensional object having a plurality of faces, each face being associated with a respective set of original boundaries;
determining, by the computing system, a respective set of expanded boundaries for one or more of the plurality of faces, wherein a set of expanded boundaries corresponding to at least a first face are determined based at least in part on an adjusted mapping angle; and
mapping, by the computing system, respective portions of the spherical media content item to each of the one or more faces, wherein a first portion of the spherical media content item is projected onto the first face at the adjusted mapping angle.

2. The computer-implemented method of claim 1 , the method further comprising:
determining, by the computing system, a mapping angle for projecting the first portion of the spherical media content item to the first face of the three-dimensional object based at least in part on a set of original boundaries corresponding to the first face; and
adjusting, by the computing system, the mapping angle, wherein the first portion of the spherical media content item is projected onto the first face at the adjusted mapping angle.

3. The computer-implemented method of claim 2 , wherein the adjusted mapping angle is greater than the mapping angle.

4. The computer-implemented method of claim 1 , wherein mapping respective portions of the spherical media content item to each of the one or more faces further comprises:
causing, by the computing system, a second portion of the spherical media content item to be projected to a second face of the three-dimensional object, the second face having a set of expanded boundaries, wherein the second face is adjacent to the first face, and wherein the projected first portion and the projected second portion overlap at least partially.

5. The computer-implemented method of claim 1 , wherein the three-dimensional object is a cube, and wherein a respective portion of the spherical media content item is mapped to each face of the cube.

6. The computer-implemented method of claim 5 , wherein a top view portion of the spherical media content item is mapped to a top view square in the cube, a left view portion of the spherical media content item is mapped to a left view square in the cube, a right view portion of the spherical media content item is mapped to a right view square in the cube, a front view portion of the spherical media content item is mapped to a front view square in the cube, a back view portion of the spherical media content item is mapped to a back view square in the cube, and a bottom view portion of the spherical media content item is mapped to a bottom view square in the cube.

7. The computer-implemented method of claim 1 , the method further comprising:
applying, by the computing system, an image obscuring process to at least a portion of the first face.

8. The computer-implemented method of claim 7 , wherein applying the image obscuring process further comprises:
applying, by the computing system, a low-pass filter to the portion of the first face.

9. The computer-implemented method of claim 7 , wherein applying the image obscuring process further comprises:
applying, by the computing system, a blur to the portion of the first face.

10. A system comprising:
at least one processor; and
a memory storing instructions that, when executed by the at least one processor, cause the system to perform:
obtaining a spherical media content item that captures at least one scene from a plurality of different positions;
determining a three-dimensional object having a plurality of faces, each face being associated with a respective set of original boundaries;
determining a respective set of expanded boundaries for one or more of the plurality of faces, wherein a set of expanded boundaries corresponding to at least a first face are determined based at least in part on an adjusted mapping angle; and
mapping respective portions of the spherical media content item to each of the one or more faces, wherein a first portion of the spherical media content item is projected onto the first face at the adjusted mapping angle.

11. The system claim 10 , wherein the system further performs:
determining a mapping angle for projecting the first portion of the spherical media content item to the first face of the three-dimensional object based at least in part on a set of original boundaries corresponding to the first face; and
adjusting the mapping angle, wherein the first portion of the spherical media content item is projected onto the first face at the adjusted mapping angle.

12. The system claim 11 , wherein the adjusted mapping angle is greater than the mapping angle.

13. The system claim 10 , wherein mapping respective portions of the spherical media content item to each of the one or more faces further causes the system to perform:
causing a second portion of the spherical media content item to be projected to a second face of the three-dimensional object, the second face having a set of expanded boundaries, wherein the second face is adjacent to the first face, and wherein the projected first portion and the projected second portion overlap at least partially.

14. A non-transitory computer-readable storage medium including instructions that, when executed by at least one processor of a computing system, cause the computing system to perform a method comprising:
obtaining a spherical media content item that captures at least one scene from a plurality of different positions;
determining a three-dimensional object having a plurality of faces, each face being associated with a respective set of original boundaries;
determining a respective set of expanded boundaries for one or more of the plurality of faces, wherein a set of expanded boundaries corresponding to at least a first face are determined based at least in part on an adjusted mapping angle; and
mapping respective portions of the spherical media content item to each of the one or more faces, wherein a first portion of the spherical media content item is projected onto the first face at the adjusted mapping angle.

15. The non-transitory computer-readable storage medium of claim 14 , wherein the system further performs:
determining a mapping angle for projecting the first portion of the spherical media content item to the first face of the three-dimensional object based at least in part on a set of original boundaries corresponding to the first face; and
adjusting the mapping angle, wherein the first portion of the spherical media content item is projected onto the first face at the adjusted mapping angle.

16. The non-transitory computer-readable storage medium of claim 15 , wherein the adjusted mapping angle is greater than the mapping angle.

17. The non-transitory computer-readable storage medium of claim 14 , wherein mapping respective portions of the spherical media content item to each of the one or more faces further causes the system to perform:
causing a second portion of the spherical media content item to be projected to a second face of the three-dimensional object, the second face having a set of expanded boundaries, wherein the second face is adjacent to the first face, and wherein the projected first portion and the projected second portion overlap at least partially.
