Title: METHOD AND APPARATUSES FOR DETERMINING POSITIONS OF MULTI-DIRECTIONAL IMAGE CAPTURE APPARATUSES
Abstract:
This specification describes a method comprising performing image re-projection on each of a plurality of first images (21 ), wherein each first image is captured by a camera (11) of a respective one of a plurality of multi-directional image capture apparatuses (10), thereby to generate a plurality of re- projected second images (22) which are each associated with a respective virtual camera, processing the plurality of second images to generate respective positions of the virtual cameras associated with the second images, and based on the generated positions of the virtual cameras, determining a position of each of the plurality of multi-directional image capture apparatuses.
