    Abstract: Disclosed are a method for generating point cloud data, an electronic device and a storage medium. The method includes: acquiring a set of real point clouds for a target object based on a LiDAR; performing image acquisition on the target object, and generating a set of pseudo point clouds based on an acquired image; and generating the set of target point clouds for model training by fusing the set of real point clouds and the set of pseudo point clouds.

    Abstract: The present disclosure provides a method and apparatus for training a reference frame screening model, a method and apparatus for screening a reference frame, an electronic device, a storage medium, and a computer program product, relates to the field of artificial intelligence. An implementation scheme is: acquiring a training sample set, where training samples in the training sample set include a sequence of video frames and labels corresponding to video frames in the sequence of video frames, and the labels are used to represent whether the video frames corresponding to the labels are reference frames of other video frames in the sequence of video frames; and training, using a machine learning method, using the sequence of video frames as input, using the labels corresponding to the input sequence of video frames as desired output, to obtain a reference frame screening model.

    Abstract: A method and apparatus for prompting navigation information. The method includes: acquiring, when a user is in an underground vehicle area, traffic behavior statuses of an underground vehicle at stops on a preset navigation route; determining, in response to the traffic behavior status of each stop of adjacent stops on the navigation route being consistent with a first preset traffic behavior status, a base station corresponding to a latter stop in the adjacent stops as a reference station; determining a location of a preset stop on the navigation route, based on a location of the reference station and locations of base stations provided at the stops; and outputting, in response to the traffic behavior status of the underground vehicle at the preset stop being consistent with a second preset traffic behavior status, prompt information for getting off.

    Abstract: A data transmission method and apparatus, an electronic device, a computer readable storage medium, and a computer program product are provided. The method includes: receiving to-be-transmitted data currently transmitted from a data source node; determining an average receiving interval and an average transmitting interval based on a historical data receiving interval and a historical data transmitting interval; determining the splitting transmission number based on the average receiving interval and the average transmitting interval; obtaining a plurality of data fragments based on a data size of the to-be-transmitted data and the splitting transmission number; and sequentially and uniformly transmitting the data fragments to a next-level node within a subsequent period with a duration being the average receiving interval.

    Abstract: A method for redirecting an edge node for a client includes: determining a peak bandwidth of a target region based on peak bandwidths of edge nodes in the target region, in which there are at least two edge nodes in the target region; determining a bandwidth ratio of each edge node based on the peak bandwidth of the target region and peak bandwidth of each edge node; obtaining a hash value of a data request address of a client request data by calculating the data request address using a preset algorithm; and determining one target edge node as an edge node of the client request data from the edge nodes of the target region based on the hash value and the bandwidth ratio of each edge node.
