  • Publication number: 20250056049
    Abstract: 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.

  • Publication number: 20240357012
    Abstract: According to some embodiments, there is provided a Collective Perception Message, CPM, characterizing a plurality of Vulnerable Road Users based on a plurality of received VAMs, thereby allowing an ITS station to efficiently aggregate VAM messages from VRUs and retransmit information about the VRUs to other ITS stations. Consequently, the security is improved as some ITS stations may not be able to detect or identify VRU stations by themselves but thanks to the CPM, these stations can still be informed of the VRUs. According to other aspects, congestion is avoided while maintaining safety vis-à-vis VRUs thanks to the use of a different transmission scheme when the VRU is already characterized in a CPM sent to the ITS stations. Also, a receiving station can evaluate whether the content of a CPM can be trusted or not. Safety is thus improved. This is achieved thanks to the CPM that references a certificate.
