The invention discloses a
point cloud attribute encoding method, a decoding method, encoding equipment and decoding equipment. The
point cloud attribute encoding method and decoding method comprise the following steps of: selecting the first K points of the
current point as neighbor points according to the Morton sequence, calculating the distance between each point in the
point cloud and the
centroid coordinates of the neighbor points, comparing the distance with a
distance threshold, and determining the attribute prediction value of the
current point according to the relationship between thedistance and the
distance threshold; and finally, performing attribute encoding according to the attribute prediction value or determining an attribute value of the
current point according to the attribute prediction value of the current point and a point cloud attribute code
stream. According to the point cloud attribute encoding method and decoding method provided by the invention, the utilization of the correlation between the geometric information and the attribute information of the point cloud can be improved, so that the encoding and decoding performance of the point cloud attribute isimproved.
