FIELD: information technology.
SUBSTANCE: invention relates to the field of encoding a point cloud. The first signal information is received from an encoded bit stream for a point cloud, which includes a set of points in a three-dimensional (3D) space. The first signal information indicates information about splitting the point cloud. The second signal information is determined based on the first signal information indicating the first value. The second signal information indicates a mode of splitting the set of points in the three-dimensional space. Next, the mode of splitting the set of points in the three-dimensional space is determined based on the second signal information. After that, the point cloud is restored based on the splitting mode.
EFFECT: provision of a possibility of compression of a point cloud without losses.
