Abstract
Disclosed herein is a method of generating images for a multi-projection theater and a method of generating projection images for a multi-projection theater, wherein a source image is mapped to a sphere, virtual planes according to the structure of a multi-projection theater are generated, and the source image on the sphere is projected on the virtual planes. The method may include mapping a source image to a sphere, generating a virtual plane according to the structure of a theater, and projecting the image on the sphere on the virtual plane.

A method of generating an image, the method performed by an image management apparatus having a controller, a communication unit, an image generation unit, and a database unit, the method comprising:
- mapping, by the image generation unit, a source image to a sphere;
- generating, by the image generation unit, a plurality of virtual planes according to a structure of a theater, the theater comprising a plurality of projection surfaces;
- projecting, by the image generation unit, the mapped source image on the plurality of the virtual planes;
- generating, by the image generation unit, a plurality of projection images to be projected on the plurality of the projection surfaces based on the projected mapped image on the plurality of the virtual planes;
- and
- sending, by the controller, the plurality of projection images to the theater through the communication unit,
- wherein the plurality of the virtual planes is generated based on a structural data of the theater stored in the database unit,
- wherein the source image comprises a plurality of pixels represented on a planar coordinate system using a horizontal angle value and a vertical angle value as parameters, and
- wherein each pixel of the plurality of pixels is mapped to a location corresponding to its horizontal angle value and vertical angle value around a center of the sphere.
A non-transitory computer readable recording medium recording a computer program for causing a computer to execute a method for generating an image, the computer having a controller, a communication unit, an image generation unit, and a database unit, the method comprising:
- mapping, by the image generation unit, a source image to a sphere;
- generating, by the image generation unit, a plurality of virtual planes according to a structure of a theater, the theater comprising a plurality of projection surfaces;
- projecting, by the image generation unit, the mapped source image on the plurality of the virtual planes;
- generating, by the image generation unit, a plurality of projection images to be projected on the plurality of the projection surfaces based on the projected mapped image on the plurality of the virtual planes;
- and
- sending, by the controller, the plurality of projection images to the theater through the communication unit,
- wherein the plurality of the virtual planes is generated based on a structural data of the theater stored in the database unit,
- wherein the source image comprises a plurality of pixels represented on a planar coordinate system using a horizontal angle value and a vertical angle value as parameters, and
- wherein each pixel of the plurality of pixels is mapped to a location corresponding to its horizontal angle value and vertical angle value around a center of the sphere.
