Abstract

Este método de codificación de datos tridimensionales: divide (S2631) una pluralidad de puntos tridimensionales incluidos en datos tridimensionales en una pluralidad de subgrupos de puntos tridimensionales que incluyen un primer subgrupo de puntos tridimensionales y un segundo subgrupo de puntos tridimensionales; adjunta (S2632) la primera información espacial del primer subgrupo de puntos tridimensionales a un encabezado del primer subgrupo de puntos tridimensionales, y adjunta la segunda información espacial del segundo subgrupo de puntos tridimensionales a un encabezado del segundo subgrupo de puntos tridimensionales; y luego codifica (S2633) el primer subgrupo de puntos tridimensionales y el segundo subgrupo de puntos tridimensionales de manera que los mismos puedan ser decodificados independientemente.
