    摘要： An image processing method includes a transmitting terminal receiving a feedback message sent by a receiving terminal. The feedback message indicates a reception state of a received image frame sent by the transmitting terminal and received by the receiving terminal before the receiving terminal sends the feedback message. The method further includes acquiring a target image frame, encoding the target image frame according to a preset error correction mechanism to generate encoding data of the target image frame in response to the feedback message indicating a reception error, and sending the encoding data of the target image frame to the receiving terminal.

    摘要： The systems and methods are provided to provide communication coverage to an unmanned aerial vehicle. A proposed flight path of a UAV may be collected, and a communication signal distribution, such as a cellular signal distribution, along the proposed flight of the UAV may be determined. At positions having low or no communication signal, relays may be provided to improve a quality of the communication signal. The relay may be a ground device or an aerial vehicle. A stable and continuous communication between the UAV and user terminals during the entire flight path of UAV may be provided, and a coverage of cellular signal may be expanded.
