Zusammenfassung:There is provided a scalable point cloud encoding/decoding method and apparatus. The scalable point cloud decoding method comprises: acquiring an encoded texture image, an encoded geometry image, encoded occupancy map information, and encoded auxiliary patch-info information from a bitstream; acquiring a decoded texture image for each partition using the encoded texture image; reconstructing a geometry image of at least one item selected from among the encoded geometry image, the encoded occupancy map information, and the encoded auxiliary catch-info information; and reconstructing a point cloud using the texture images for the respective partitions and the geometry image.
