METHODS AND APPARATUSES FOR DETERMINING POSITIONS OF MULTI-DIRECTIONAL IMAGE CAPTURE APPARATUSES
First Claim
1. A method comprising:
- performing image re-projection on a plurality of first images of a scene to generate a plurality of re-projected second images of the scene, wherein each first image of the scene is captured by a respective camera of a first multi-directional image capture apparatus and each second image of the scene is associated with a respective virtual camera;
processing the plurality of re-projected second images based on a previously generated virtual three dimensional model of the scene to generate respective positions of the virtual cameras associated with the second images; and
determining a position of the first multi-directional image capture apparatus based on one or more of the generated respective positions of the virtual cameras.

Abstract
A method comprising performing image re-projection on each of a plurality of first images of a scene, thereby to generate a plurality of re-projected second images of the scene, wherein each first image of the scene is captured by a respective camera of a first multi-directional image capture apparatus and each second image of the scene is associated with a respective virtual camera; processing the plurality of second images based on a previously generated virtual three dimensional model of the scene, thereby to generate respective positions of the virtual cameras associated with the second images; and determining a position of the first multi-directional image capture apparatus based on one or more of the generated positions of the virtual cameras.

10. Apparatus comprising:
-
at least one processor; and at least one memory including computer program code, which when executed by the at least one processor, causes the apparatus to; perform image re-projection on a plurality of first images of a scene to generate a plurality of re-projected second images of the scene, wherein each first image of the scene is captured by a respective camera of a first multi-directional image capture apparatus and each second image of the scene is associated with a respective virtual camera; process the plurality of re-projected second images based on a previously generated virtual three dimensional model of the scene to generate respective positions of the virtual cameras associated with the second images; and determine a position of the first multi-directional image capture apparatus based on one or more of the generated respective positions of the virtual cameras. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19)

20. A computer-readable medium having computer-readable code stored thereon, the computer readable code, when executed by at least one processor, causes an apparatus to:
-
performing image re-projection on a plurality of first images of a scene to generate a plurality of re-projected second images of the scene, wherein each first image of the scene is captured by a respective camera of a first multi-directional image capture apparatus and each second image of the scene is associated with a respective virtual camera; processing the plurality of re-projected second images based on a previously generated virtual three dimensional model of the scene to generate respective positions of the virtual cameras associated with the second images; and determining a position of the first multi-directional image capture apparatus based on one or more of the generated respective positions of the virtual cameras.
