Abstract: Disclosed herein are an apparatus for estimating a camera pose using multi-view images of a 2D array structure and a method using the same. The method performed by the apparatus includes acquiring multi-view images from a 2D array camera system, forming a 2D image link structure corresponding to the multi-view images in consideration of the geometric structure of the camera system, estimating an initial camera pose based on an adjacent image extracted from the 2D image link structure and a pair of corresponding feature points, and estimating a final camera pose by reconstructing a 3D structure based on the initial camera pose and performing correction so as to minimize a reprojection error of the reconstructed 3D structure.

Abstract: Provided is a system and method for transmitting and receiving 3D video based on digital broadcasting. The system includes: an encoder for generating 2D ES and 3D supplementary ES by encoding 2D video and 3D supplementary data; a packetizer for generating 2D video PES and 3D supplementary PES by packetizing the 2D video ES and the 3D supplementary ES; a PSI generator for generating a PSI; a TS generator for generating 2D video TS and 3D supplementary TS for the 2D video PES and the 3D supplementary PES; a multiplexer for multiplexing the transport streams to transmit the 2D video TS as a normal stream and transmit the 3D supplementary TS, the PSI TS and 3D video synch data TS as robust stream; and a modulator for modulating the multiplexed TS according to a DTV specification and transmitting the modulated TS.
