  • Patent number: 11908152
    Abstract: The present invention belongs to the field of image processing and computer vision, and discloses an acceleration method of depth estimation for multiband stereo cameras. In the process of depth estimation, during binocular stereo matching in each band, through compression of matched images, on one hand, disparity equipotential errors caused by binocular image correction can be offset to make the matching more accurate, and on the other hand, calculation overhead is reduced. In addition, before cost aggregation, cost diagrams are transversely compressed and sparsely matched, thereby reducing the calculation overhead again. Disparity diagrams obtained under different modes are fused to obtain all-weather, more complete and more accurate depth information.

  • Publication number: 20230413238
    Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for determining shared resources associated with one or more user equipments (UEs) for sidelink communications, including control resources and data resources. A first UE may transmit a sidelink request to reserve a subset of data resources to a second UE, and may monitor for one or more sidelink responses indicating a positive sidelink response to the sidelink request, a negative sidelink response to the sidelink request, or both. The second UE may transmit a positive sidelink response if it is available for a data transmission. A third UE may transmit a negative sidelink response if it objects to the data transmission. The first UE may determine, based on monitoring for the one or more sidelink responses, whether to transmit a sidelink confirmation indicating a reservation of the subset of the data resources to the second UE.
