Method and apparatus for receiving multiview camera parameters for stereoscopic image, and method and apparatus for transmitting multiview camera parameters for stereoscopic image

摘要

Provided is a method of receiving multiview camera parameters for a stereoscopic image. The method includes: extracting multiview camera parameter information for a predetermined data section from a received stereoscopic image data stream; extracting matrix information including at least one of translation matrix information and rotation matrix information for the predetermined data section from the multiview camera parameter information; and restoring coordinate systems of multiview cameras by using the extracted matrix information.

1. A method of reconstructing a stereoscopic image from a stereoscopic image bitstream in which stereoscopic image data is inserted, the method comprising:
parsing the stereoscopic image bitstream and reading a camera parameter regarding a frame section comprising at least one frame of the stereoscopic image from the stereoscopic image bitstream; extracting camera parameter insertion information indicating whether the camera parameter for a base view camera and an additional view camera which obtain the stereoscopic image is inserted in the stereoscopic image bitstream, from the camera parameter; extracting translation information regarding a relative distance from the base view camera to the additional view camera from the camera parameter, based on the camera parameter insertion information; discovering whether the base view camera and the additional view camera are arranged in cross arrangement, and extracting rotation information regarding a relative rotation angle from the base view camera to the additional view camera from the camera parameter, based on the camera parameter insertion information and the arrangement of the base view camera and the additional view camera; and reconstructing the stereoscopic image using the stereoscopic image data extracted from the stereoscopic image bitstream, and wherein the camera parameter is used to display the reconstructed stereoscopic image in three-dimensional display mode, wherein the relative distance is a translation value from an origin of a coordinate system of the base view camera to an origin of a coordinate system of the additional view camera, and wherein the relative rotation angle is an angle value from a coordinate axis of the coordinate system of the base view camera to a corresponding coordinate axis of the coordinate system of the additional view camera.
