摘要

The present principles relates to a method and device for encoding an input colored point cloud representing the geometry and colors of a 3D object. The method comprises: —selecting (100) at least one face (F_i,j) of at least one cube (C_j) of an octree-based structure of projection according to at least one orthogonal projection of the point cloud onto said at least one face; and —encoding (120, 130) a pair of one texture image (TI_i,j) and one depth (DI_i,j) image per selected face (F_i,j) of a cube (C_j) by orthogonally projecting the part of the point cloud included in said cube (C_j) onto said selected face (F_i,j).
