Abstract
Un método de codificación de datos tridimensionales incluye: La codificación de un primer indicador que indica si un nodo que tiene un nodo padre diferente de un nodo padre de un nodo actual debe ser referido en la codificación del nodo actual incluido en una estructura de árbol N-ari de puntos tridimensionales incluidos en los datos tridimensionales, siendo N un número entero mayor o igual a 2 (S3661); seleccionando una tabla de codificación de N tablas de codificación según los estados de ocupación de los nodos vecinos del nodo actual, y realizando la codificación aritmética de la información del nodo actual usando la tabla de codificación seleccionada, cuando el primer indicador indica que se debe hacer referencia al nodo (SÍ en S3662) (S3663); y seleccionar una tabla de codificación de las tablas de codificación M según los estados de ocupación de los nodos vecinos del nodo actual, y realizar la codificación aritmética de la información del nodo actual usando la tabla de codificación seleccionada, cuando el primer indicador indica que no se debe hacer referencia al nodo (NO en S3662), siendo M un número entero diferente de N (S3664).
