The present application provides a point cloud encoding and decoding method and apparatus, a device, and a storage medium. The method comprises: in octree-based point cloud decoding, when decoding a current node of an N-1 layer in the octree, first determining a first parameter corresponding to the current node, the first parameter being used for determining whether at least one non-zero sub-node of the current node comprises a repeated point, wherein the current node is a non-zero node of the N-1 layer in the octree of the point cloud and N is the total number of layers of the octree, and then, based on the first parameter, performing geometric decoding on the current node. For example, when it is determined on the basis of the first parameter that an ith non-zero sub-node of the current node does not comprise a repeated point, then skipping the decoding of the repeated point information of the ith non-zero sub-node, thereby reducing point cloud decoding complexity, saving decoding time, and improving decoding efficiency.
