Abstract
(EN)
Disclosed are a point cloud encoding/decoding method and an encoder/decoder, which relate to the technical field of encoding and decoding, and facilitate an improvement in coding and decoding performance. A point cloud decoding method (comprising a point cloud encoding method or a point cloud decoding method) comprises: setting a value of a pixel of a preset target position in a boundary pixel block to be processed in a filled occupation map of a point cloud to be decoded as zero, so as to obtain a pixel block that is set as zero; and reconstructing the point cloud to be decoded according to the processed occupation map, wherein the processed occupation map comprises the pixel block that is set as zero.

L'invention concerne un procédé de codage/décodage de nuage de points et un codeur/décodeur, qui se rapportent au domaine technique du codage et du décodage et facilitent une amélioration des performances de codage et de décodage. Un procédé de décodage de nuage de points (comprenant un procédé de codage de nuage de points ou un procédé de décodage de nuage de points) consiste à : définir comme zéro une valeur d'un pixel d'une position cible prédéfinie dans un bloc de pixels de frontière à traiter dans une carte d'occupation remplie d'un nuage de points à décoder, de façon à obtenir un bloc de pixels qui est défini comme zéro; et reconstruire le nuage de points à décoder en fonction de la carte d'occupation traitée, la carte d'occupation traitée comprenant le bloc de pixels qui est défini comme zéro.
