1. A multi-view image decoding method, the method comprising:
obtaining, from a bitstream, three-dimensional geometry information indicating a three-dimensional space of a multi-view image, view independent component information indicating a view independent component, which is uniformly applied to every view, and view dependent component information indicating a view dependent component, which is differently applied according to views;
determining the view dependent component for a texture map of a current view from the view dependent component information;
generating the texture map of the current view from the view independent component of the view independent component information and the determined view dependent component for the current view; and
reconstructing a current view image according to the texture map of the current view and the three-dimensional space that is constructed according to the three-dimensional geometry information,
wherein the three-dimensional space is defined by a triangular mesh structure in the unit of voxels, the triangular mesh structure for each voxel set as one among a plurality of pre-determined triangular mesh structure pattern candidates,
wherein the three-dimensional geometry information is index information for indicating the triangular mesh structure for each voxel from among the plurality of pre-determined triangular mesh structure pattern candidates, and
at least some of the plurality of pre-determined triangular mesh structure pattern candidates are defined at least based on preset UV locations.
