Abstract:
This method for encoding a 3D point cloud comprises: —segmenting the point cloud into first patches (2); —determining inverse projection parameters of the patches (4); —projecting the first patches to planes using the inverse projection parameters (10); —encoding the planes (12); —determining sparse points in the point cloud not belonging to any patch (HC, 18); and—encoding the sparse points using an octree-decomposition (20).
