Abstract
A system and method generates a broadcast image. The method includes receiving a first image captured by a first camera having a first configuration incorporating a first center of projection. The method includes determining a first mapping from a first image plane of the first camera onto a sphere. The method includes determining a second mapping from the sphere to a second image plane of a second virtual camera having a second configuration incorporating the first center of projection of the first configuration. The method includes generating a second image based upon the first image and a concatenation of the first and second mappings.
Claims20
A method, comprising:
- receiving a first image captured by a first camera having a first configuration incorporating a first center of projection;
- determining a first mapping from a first image plane of the first camera onto a sphere;
- determining a second mapping from the sphere to a second image plane of a second virtual camera having a second configuration incorporating the first center of projection of the first configuration;
- and
- generating a second image based upon the first image and a concatenation of the first and second mappings.
A device, comprising:
- a processor coupled to a memory, wherein the processor is programmed to generate a broadcast image by:
- receiving a first image captured by a first camera having a first configuration incorporating a first center of projection;
- determining a first mapping from a first image plane of the first camera onto a sphere;
- determining a second mapping from the sphere to a second image plane of a second virtual camera having a second configuration incorporating the first center of projection of the first configuration;
- and
- generating a second image based upon the first image and a concatenation of the first and second mappings.
A non-transitory computer readable storage medium including a set of instructions executable by a processor, the set of instructions operable to:
- receive a first image captured by a first camera having a first configuration incorporating a first center of projection;
- determine a first mapping from a first image plane of the first camera onto a sphere;
- determine a second mapping from the sphere to a second image plane of a second virtual camera having a second configuration incorporating the first center of projection of the first configuration;
- and
- generate a second image based upon the first image and a concatenation of the first and second mappings.
