1. A point cloud encoding processing method, comprising:
determining sparsity level information of a target point cloud; and
in a case that the sparsity level information indicates the target point cloud being a sparse point cloud and a node to be encoded corresponding to the target point cloud satisfies an isolated point encoding condition, enabling an isolated point encoding mode;
wherein the determining sparsity level information of a target point cloud comprises:
determining the sparsity level information of the target point cloud based on a target volume corresponding to the target point cloud and the number of target points contained in the target point cloud;
wherein the determining the sparsity level information of the target point cloud based on a target volume corresponding to the target point cloud and the number of target points contained in the target point cloud comprises:
dividing the target volume by the number of target points to obtain a first value; and
determining the sparsity level information of the target point cloud based on a relationship between the first value and a predetermined threshold.
