  • Publication number: 20240147202
    Abstract: A transmitter generates a V2X message, where the V2X message includes reference object indication information and position indication information, the reference object indication information indicates at least one reference object, and the position indication information indicates a position of a target object relative to the at least one reference object; the transmitter sends the V2X message to a receiver; and the receiver determines target position information of the target object based on the reference object indication information and the position indication information. In the foregoing process, the transmitter transfers relative position information relative to the reference object to the receiver by using the V2X message, and does not need to perform deflection. In addition, the V2X message indicates a reference object on which position information is based.

  • Publication number: 20240041947
    Abstract: A relay directional molecular communication method based on multiple attractants is applied in a field of molecular communication to address the inefficiency of existing technologies. The method for relay nodes is used by fixing three types of attractants, and the relay nodes only release one of the three types of attractants. By using relative priority between two attractants, nanomachines can quickly find a target. Compared with existing multi-attractant multi-relay algorithms, the method does not require many types of attractant resources due to the three types of attractants, saves a variety of the attractant resources, and still achieves an effect greater than three hop relays. It is realized that when a number of the relay nodes is certain, not only the type of attractants used can be reduced, but also the efficiency of finding the target can be maintained.

  • Patent number: 11893799
    Abstract: Technologies and techniques for vehicle perception. Contours are extracted from image data, and a first and second contour of a current image and next image are determined along a plurality of image row boundaries, wherein the contours includes a plurality of contour points linked to each other via respective edges. An image velocity vector is applied to project each of the plurality of first contour points to the next image, wherein at least some of the projected first contour points are not located on an image row boundary. The projected contour points are processed to determine projected edges forming a projected link between each projected contour point. The projected contour points are moved along the projected link to align each of the moved projected contour points to a respective image boundary. Each of the moved projected contour points are then linked to each of the second contour points.
