METHOD AND DEVICE FOR PROCESSING A GEOMETRY IMAGE OF A 3D SCENE

Provided are a method for processing a geometry image, which is generated from a message related to a 3D scene, and has a plurality of charts to respectively display a part of the 3D scene, and an apparatus thereof. According to the present invention, the method comprises the steps of: calculating a reference direction (21) from a mesh coordinate related to a current pixel (203), and a mesh coordinate related to a first pixel (213), wherein the first pixel (213) corresponds to a boundary pixel of a first chart positioned along a determined direction (20) having the current pixel (203) as an origin; comparing the reference direction (21) with a set (22, 23, 24, 25, 26) of candidate directions, wherein each of the candidate directions is calculated from at least one among the mesh coordinate related to the current pixel (203), and an indirect mesh coordinate related to one adjacent pixel (222 or 226, 212 or 214) of the first pixel (213), and the indirect mesh coordinate corresponds to the mesh coordinate of the boundary pixel of a second chart corresponding to the adjacent pixel of the first pixel; and selecting the boundary pixel of the second chart depending on a comparison result.
