Publication number: 20250056049Abstract: A method for encapsulating point cloud data in a file compliant with the ISOBMFF standard. After having obtained point cloud data comprising 3D points, the obtained point cloud data being organized in at least one point cloud frame, at least two sub-frames of the at least one point cloud frame are determined, a timing information being associated with each of the at least two sub-frames, the timing information associated with one of the at least two sub-frames being different from the timing information associated with the other of the at least two sub-frames. Next, metadata describing the at least two sub-frames are generated, the generated metadata comprising or describing the timing information associated with each of the at least two sub-frames, and the obtained 3D points and the generated metadata are encapsulated in the file, each point cloud frame being encapsulated as one or more samples.Type: ApplicationFiled: December 15, 2022Publication date: February 13, 2025Inventors: Franck DENOUAL, Frédéric MAZE, Naël OUEDRAOGO, Hervé RUELLAN, Lionel TOCZE
