3results about How to "Improve sending efficiency" patented technology

The application discloses a point cloud information processing method, device and equipment and a storage medium, and comprises the following steps: acquiring current point cloud frame data, wherein the current point cloud frame data comprises three-dimensional coordinate information of a plurality of point clouds; performing two-dimensional space mapping processing on the three-dimensional coordinate information of the plurality of point clouds to obtain a current depth image corresponding to the current point cloud frame data; comparing the current depth image with a previous depth image to obtain a frame difference image, wherein the previous depth image is a depth image corresponding to previous point cloud frame data adjacent to the current point cloud frame data; determining a target sending image from the current depth image and the frame difference image with smaller data quantity; and sending the target sending image to an image rendering module. The application can effectively reduce the data quantity of point cloud data, facilitate the storage and sending of point cloud data, and ensure real-time transmission of point cloud data.

The present disclosure relates to a data sending method and device, electronic equipment and storage medium. The method comprises: in the scenario of uplink resource allocation exception, selecting a plurality of target subcarriers from a plurality of alternative subcarriers, the alternative subcarriers being subcarriers available for sending data, the number of the plurality of target subcarriers being less than the number of the plurality of alternative subcarriers; and sending data based on the plurality of target subcarriers. In the method, each target subcarrier has more power to support data sending, reducing the decoding failure of the network device, reducing the bit error rate, improving the data sending efficiency, avoiding the problems of resource waste and data flow interruption, and improving the user experience.
