摘要：
This method for encoding a point cloud comprises:
- segmenting (2) the point cloud into first plane-like patches;
- projecting (10) the first plane-like patches to projected planes using inverse projection parameters;
- encoding (12) the projected planes;
- determining (18) sparse points in the point cloud; and
- encoding (20) the sparse points using an octree-decomposition.
