MUMBAI, India, May 30 -- Intellectual Property India has published a patent application (202517045319 A) filed by Beijing Xiaomi Mobile Software Co. Ltd., Beijing, on May 10, for 'method for encoding and decoding a 3d point cloud encoder decoder.'
Inventor(s) include Gao Shuo.
The application for the patent was published on May 30, under issue no. 22/2025.
According to the abstract released by the Intellectual Property India: "Method for decoding from a bitstream the geometry of a 3D point cloud preferably implemented in a decoder including: receiving and decoding a bitstream wherein the bitstream contains octree information including information about octree structure of the volume of the point cloud and vertex information including information about vertex presence and position of a vertex on edges of cuboids of leaf nodes of the octree structure; determining triangles by connecting the vertices of one cuboid relating to a leaf node of the octree structure; voxelization of the triangles to de termine points of the point cloud characterized in that the method further comprising: wherein determining whether an additional information contained in the bitstream meets a pre defined condition wherein the additional information is determined based on a dense degree of the point cloud preferably evaluated by a sampling distance dsampl of the point cloud; when the pre defined condition is met at least one triangle is extended along at least one side for voxelization based on a the sampling distance dsampl of the point cloud."
The patent application was internationally filed on Oct. 17, 2022, under International application No.PCT/CN2022/125769.
